P 86: encoder adjustment (only for synchronous motors, MFC 21-xx, MFC 31-xx) As the incremental encoder (absolute sine-cosine-encoder) on the synchronous machine not only determines the speed (impulses per motor revolution) but also the absolute location of the rotor, an additional encoder adjustment must be carried out after replacement of the incremental encoder. The encoder does not have to be aligned manually. It is sufficient when it is mounted in a fixed position. After carrying out the encoder adjustment (aligning the rotor), the calibration takes place by saving in the EEPROM of the encoder. The data is retained even after the supply voltage is switched off. Preparation: •
Set up load compensation in the elevator system. If there is no load compensation, the encoder could be incorrectly adjusted.
•
Set the elevator system to electrical recall
•

Warning P 92: discharge DC circui Before working on the frequency inverters or motor connections, the DC circuit must be discharged in the interests of safety (see part 1). This function parameter displays the intermediate circuit voltage in Volts. Simultaneously pressing the ”+” and ”-” buttons starts a function that activates the chopper resistor in cycles and thus discharges the DC circuit capacitor. The discharge operation can be accelerated if the P/W button is pressed at the same time. Discharging the DC circuit only works if the signal ”QSP” = 0, i.e. the mains contactor has de-energised and the brake resistor is not defective. On installations where the contactors are not positioned between the mains and frequency inverter rather between the motor and frequency inverter, the power supply must be switched off before discharging the DC circuit. However, the control voltage must remain on until the DC circuit has been discharged. P 96: number of encoder marks The selection of the number of encoder marks is made here. The number of marks of the deployed encoder can be read off in the vicinity of the encoder on the motor casing. If unknown, the number of encoder marks can be determined as described in parameter P 105.

B) Work on the frequency inverter To work on the frequency inverter (except for setting up procedures using the operating keyboard) or the motor, the following measures are required: •
shut down
•
secure against reactivation
•
determine that there is no voltage
C) Determining there is no voltage Particular attention is to be paid to the fact that even after the mains voltage has been switched off there can still be electrical energy in the device (capacitor charge). This applies in particular in the case of a defective device. For this reason, a check for residual voltage must be carried out before starting any work on the frequency inverter. To check for residual voltage, a suitable multimeter (at least 800 V direct current) can be used to directly measure the intermediate circuit voltage at terminal block X1, terminals 22 and 23. •

Commissioning - Notes on operation
Note Set the measuring instrument to the direct current range (DC)! Work on an opened device with applied intermediate circuit voltage (approx. 700 V DC) is only to be performed in exceptional cases and only with the greatest caution. Here, particular attention is to be paid to the fact that the intermediate circuit voltage has a fixed potential relationship to the mains voltage and to the protective earth.
2.2
Notes on operation
Note The frequency inverters contain components that are subject to electrostatic risks. Before performing service work on the frequency inverters (e.g. replacement of printed circuit boards), the service personnel must eliminate static charges by touching an earthed metallic surface.
Warning In the event of incorrect assignment of the frequency inverter to the motor, the frequency inverter or the motor can be damaged. Frequently cyclical switching on and off of the frequency inverter can lead to an overload of the internal charging resistors. This is to avoided by allowing the corresponding breaks.
2.3

Notes: before switching on for the first time
•
Check the wiring to the frequency inverter and to the motor (including incremental encoder)
•
Check the electromagnetic compatibility of the earthing of the cable screens
•
Check of the correct protective earthing of all assemblies (frequency inverter, motor, housing and brake resistor)
•
Check of the mains voltage
•

Check of the functional capability of the drives
Specify the inspection speed vi in upward or downward direction. The drive must move in the corresponding direction with the desired inspection speed. If the drive moves at the right speed but in the wrong direction, use parameter P 3 "direction of rotation" to invert the direction. If the drive is not smooth or does not move at the right speed, a) for asynchronous motors use parameter P 4 "control direction" to invert the control direction. b) for synchronous motors perform an encoder adjustment (see P 86). If the inspection speed is not reached despite changing the control direction, check whether the incremental encoder is correctly inserted and/or the number of encoder marks is correct, see chapter 1.4.2 , page 1-28.
2.7
Optimisation of the drive A) Speed controller The parameters P 5 "speed controller P gain" (default value 8) and P 6 "speed controller I gain" (default value 50 ms) are available to optimise the speed actual value running characteristic curve. Perform this optimisation step by step. If necessary, set the ”I gain” right down to ”0” and the ”P gain” until the drive runs without any tendency to rock. Note It should be borne in mind that with the ”I gain" setting equal to "0” a sustained deviation in the actual speed occurs depending on the load direction, i.e. under certain circumstances the drive cannot accelerate in the load direction or even drifts in the wrong direction. The ”P gain” should have a safety clearance to the above tendency to rock (approx. factor 2 smaller). For normal operation, an ”I gain” not equal to ”0” is to be set again.

ThyssenKrupp Aufzugswerke Operating Manual Commissioning - Optimisation of the drive
Experience has shown that the given default values (P = 8 and I = 50 ms for asynchronous and P = 2 and I = 70 ms for synchronous) already result in very good travel quality. To assess the running characteristic curve, a recorder can be connected to MP 42A or MP 43A of the TMI printed circuit board. The common reference point is MP 26 or the housing of the frequency inverter. The selection of the measurement signals available at these display outputs is made using the parameters P 10 or P 11, see chapter 1 Parameters, page 1-1. Example: with the value "0" in P 10, the speed actual value with prefix is displayed at MP 42A. For minimizing reverse rotation on opening the brake at start, a higher P proportion (P 205) and a "faster" J proportion (P 206) can be specified. B) Run at rated speed To optimise the rated travel, the acceleration and acceleration change (jerk) can be changed with the parameters P 19 and P 20. Note Important here is that, in accordance with the selected acceleration, a minimum jerk is to be set (see chapter 2.8.2 Diagram for determining the minimum jerkpage 2-8), as otherwise there is no range of constant acceleration.
Important here is that the floor-to-floor distance is greater than the total of the acceleration and deceleration distance from rated speed (see chapter 2.8.3 Diagram for determining the minimum permitted floor-to-floor distances, page 2-9). In the case of floor-to-floor runs, this achieves the rated speed. C) Short run A short run is when the floor-to-floor distance is less than the total of the acceleration and deceleration distance from rated speed, but greater than the deceleration distance from rated speed. In the case of floor-to-floor runs, this does not achieve the rated speed. Procedure for activation of the short run (see chapter 3 Short run device, page 3-1).

If the load measurement device LMS 1 is used, the optimal initial torque can be specified. If there is no load measurement, the start can also be optimised for a certain load state.

Short run device
3.1
General A short run is when the floor-to-floor distance is shorter than the total of the acceleration and deceleration distance for rated speed. In the case of these runs, this does not achieve the rated speed. To reach the stop, the elevator would have to move at levelling speed for a longer period of time. The built-in short run device detects this state and automatically extends the acceleration phase of the run. This means that no creepage or only very short creepage occurs (switching delay or rope slip). Note For the short run device to function properly, the elevator specifications must be correctly set. These are: •
P 13
gear ratio
•
P 14
diameter of traction sheave
•
P 15
suspension
•
P 19
jerk
•
P 20
acceleration
•
P 23
speed v0
•
P 25
speed vN
These parameters are used to calculate the deceleration distance from vN and display it in parameter P 111. For each normal run (vN is reached), the deceleration distance is measured and displayed in P 112. This measured distance, however, is not taken into account in the short run computing. A special form of the short run is the short run with "sharper rounding" (see figure 3 3). This is the case when the deceleration point is reached during the upper rounding of the acceleration phase. If the deceleration takes place with the set jerk, the deceleration distance is too great. The landing is overrun. To avoid this, the elevator is run with a "sharper rounding", i.e. with greater jerk.

P 39: correction of short run distance In the event of excessive switch delay times of the control system or rope slip, it can be necessary to correct the levelling distance for a short run. If higher values are entered, the creep distance to the landing gets longer; with lower values, the creep distance gets shorter. Values from -40.0 cm to +40.0 cm are possible. Normal run vN

Modernisation
4.1
General This frequency inverter (MFC 20 or MFC 30) can also be used in the case of modernisation of elevator systems with non-ThyssenKrupp motors. These motors can be single-speed or pole changing. Vector regulation is also used here. The maximum recommended speed is 1.6 m/s. The rest of this description provides the necessary information for the modernisation.
4.2
Modernisation with encoder mounting on motor shaft The regulation of "traditional" elevator motors with a frequency inverter provides the following advantages: •
Energy reduction by up to 50% (this is not a promised value, as the energy reduction depends on many influences, e.g. the type of installation, amount of runs, etc.).
•
No 300-Hz ripple as in the case of operation with 3-phase AC controller
•
No modulation noise in the motor as in the case of frequency inverters with lower clock frequency.
To ensure that configuration for the modernisation is as easy as possible, the following specifications have been made: •
Operation of single-speed or pole changing motors as well as frequency inverter motors or standard motors is possible
•
Motors should have class of insulation F; a converter output choke is used to reduce the coil stress
•
The flywheel mass should be reduced to a maximum of 1/3 of the original value or removed completely. If the flywheel mass cannot be reduced, for example in the case of external-rotor motors, the acceleration value of the installation is to be selected in such a way that the maximum output current of the converter is adequate.
•
If possible, the encoder must be torsion-proof and mounted on the centre of the motor shaft. The encoder must deliver push-pull TTL signals with 5 V supply voltage. The assembly is to be designed, e.g., in the same way as the Wachendorff pulse generators with part number 00 990 14 030.
•
The minimum landing-to-landing distance is control-dependent; with an "internal" converter running characteristic curve, the minimum landing-to-landing distances apply, see chapter 2.8.3, Diagram for determining the minimum permitted floor-to-floor distances, page 2-9.

Settings for motor adaptation To set the frequency inverter for an unknown motor, a corresponding procedure is required; under certain circumstances, an iterative process is necessary. The starting point for this is the type plate data. Here, it should be borne in mind that this is no always complete or, in the case of old elevator motors, it does not represent the rated operating point for the frequency inverter, as the ratio of maximum current to rated current was limited to certain values. This normally leads to excessively high no-load current for the frequency inverter. The table at the end of this chapter provides an aid to orientation. To enable the following parameters, "non-ThyssenKrupp motor" must be selected in P 40. a) Run automatic current controller optimisation (auto tuning P 80). b) The parameters P 60 (“motor rated frequency”), P 61 (“motor rated voltage”), P 62 (“motor rated speed”), P 63 (“rated motor current”) and P 64 (“motor cos (phi)”) are used to calculate the values for P 65 (“rotor time constant TR”) and P 66 (“no-load current Id”). Typically, the values for P 65 are between 40 ms and 400 ms; the values for P 66 are typically between 6 Aeff and 30 Aeff (depending on the motor output).

d) These default settings provide a certain basic setting for the motor. The elevator is to be balanced out, where possible, so that only the no-load current flows (load current < 5% of the maximum current) at constant speed (e.g. electrical recall). If this is the case, a travel at rated speed should be carried out. Here, a tolerance band fault can occur on acceleration; if necessary, disable this monitoring or otherwise set a lower acceleration value. The actual motor voltage value appears in the top right of parameter P 68 (and also P 67). This value should be around 270 to 300 V at rated travel. If this is not the case, the motor voltage can be reduced by lowering the value of P 68 (no-load current Id) (usually, the motor voltage that sets in with the no-load current from the type data will be too high). The motor voltage should be around 270 to 300 V in UP and DOWN direction. If there is not sufficient torque for the acceleration phase, the rotor time constant TR in P 67 must be increased or reduced. Here, the value can be changed in steps of 25%. e) The elevator is now to be operated with the elevator car empty, followed by a motor run under load in the DOWN direction and a braking run in the UP direction. In the DOWN direction, the motor voltage should rise by approximately the slip value of the motor, i.e. approx. 30 V to 50 V; in the UP direction, the motor voltage should fall by a lower value (approx. 10 V to 30 V). If this is not the case, the value of the rotor time constant TR in P 67 must be changed in steps of 25%. This setting should be made with the motor warm (not with a very cold or very hot motor). f) The setting of the speed controller is also to be checked: The I proportion of the speed controller is to be set to 0 and the P proportion is to be increased until rocking or humming of the motor occurs. The P proportion is then to be cut by half. The I proportion is to be selected in the range from approx. 10 ms to 100 ms, depending on the overshoot in the running characteristic curve. The pre-control of the speed controller with the help of the acceleration pre-control (P 21 and P 22) additionally improves the travel quality. The running performance is to be tested with no load, half load and full load.

Installation The RS485 interface of the converter must be connected to the control system. Connector X90 is to be used, with the assignment 1=signal B, 2=signal A, 3=reference earth RS485. It is recommended to use a twisted, shielded line. Where possible, the control cabinet of the control system should be plane-connected, e.g. connected by a copper band with the housing of the converter. In this case, it is recommended to apply the screening of the DCP connection to both sides of the housing. On MFC 20 devices, the converter must be notified when the travel contactors have energised. Unfortunately, the contactor acknowledgement is not integrated in the DCP telegram traffic. For this reason, the signal must be wired in the same way as for conventional activation (input QSP1, terminal X1-10b). On MFC 30... devices, the travel contactors and contactor acknowledgements are already integrated. So that the elevator control system can perform its monitoring tasks in accordance with EN81, the relay output ("contactor control" terminal X1-4a, 5a) is available.

Note Special runs according to the DCP03 specification are also possible in the DCP4 operation mode, which is why values must also be entered for the other speeds (bit G5, G4, G0).
The nomenclature for the individual speeds has developed at the various manufacturers of elevator components independently, which means there are differences. This has resulted in a considerable risk of confusion. MFC frequency converter DCP03 / 04 documentation Kollmorgen No.

DCP04 parameters
Limit values designated with "auto" are fixed automatically by the program depending on other parameter entries. P 72 enables a certain partial distance to be run at constant speed on each run. Consequently, a lower speed is run on short runs. This slightly reduces the energy consumption and wear. The downside is that the running time increases slightly. A maximum of 1/3 of the run distance is run at constant speed, even if a longer distance is entered here. On long run distances, this setting has no effect, as a partial distance at constant speed occurs anyway. P 73 enables forcing a defined distance at creeping speed on approaching a landing instead of the direct approach. As long as the exact transformation ratios are unknown on commissioning, it is recommended to enter a higher value here. This distance already contains the deceleration distance from V0 creeping speed to zero. If zero mm is entered here, the smallest possible is set automatically. If the elevator has a tendency to run too far at the destination landing, a greater value must be entered here. P 74 see 5.1.5 Stopping accuracy with DCP04 operation, page 5-4.

DCP interface - Preface
P 75 stop position controller gain The running characteristic curve is calculated from the set parameters for speed, acceleration and jerk during almost the entire run distance and passed onto the speed controller. During the last millimetres before reaching the stop position, this strategy changes. A position controller uses the distance to the exact stop position to determine the reference values for the speed controller in such a way that the elevator comes to a standstill at virtually exactly the position specified by the DCP control system. The gain of this controller is set using P75. If an unpleasant jerk is noticeable on stopping, first set the creep distance (P 73) to a higher value, e.g. 50…100mm. Then P75 can be set in such a way that stopping is soft and pleasant. Once a setting has been found that leads to both good stopping accuracy and soft stopping, P 73 can be reset to a low value. 5.1.4
Safety function TIMEOUT control If no valid DCP telegram arrives at the converter for longer than 150 ms, the converter executes an emergency stop if the elevator is currently running. The event and fault stack of the converter then contains the entry: "DCP fault" and the number of DCP telegrams with incorrect checksum received since switching on. Furthermore, the corresponding status of the operating hour meter appears for each stack entry. Emergency stop means: block impulses, open travel contactors and close mechanical brake.
5.1.5
Stopping accuracy with DCP04 operation With DCP04 operation, particular care is required when entering the gear ratio, suspension ratio and diameter of traction sheave. Even minor inaccuracies in the diameter of traction sheave lead to inadequate stopping accuracy. The running speed on the display of the control system compared with the display of the converter, parameter P 101 "actual speed" must match during the run. If the exact diameter of traction sheave is unknown, the converter offers a mathematically determined diameter after each run on P 74 "traction sheave calculated". This is calculated from the travel information of the control system and the encoder information of the drive. However, the calculation result is falsified by rope slip and rounding errors. In order to obtain a meaningful result, a number of runs must be executed over a number of floors. The might be that P 74 shows zero mm if runs from or to the lowest landing are executed. Then, simply execute runs between two other landings and then read off P 74. If the same or almost the same value has been read a number of times on P 74, this can then be entered at P 14 "traction sheave". As a general principle, the drive tends to run too fast and too far if the input value at P 14 "traction sheave" is too low. If the input value is too high, the drive tends towards a slow approach path and slow running speed.
