3.4 Test Modes The SM150 supports several “Test Modes”” for checking essential converter functions. To analyze particular properties of the system (Infeed, Motor Module) a number of “Identification modes” are available. Following of the available “Test modes” are commonly required and applied: - Auxiliary Fan - GSV (IGCT-Test) - Crowbar thyristor - Pre-charging - Pre-charging i and Line Breaker - Line Breaker (Main CB) - Cooling System - Main Fan - Redundant Main Fan Most of the Test Modes are selected by parameter p6650 of object “Infeed” (of drive device Infeed). In the fault-free state of the Infeed the preselected test mode is activated by whatever input is assigned to p6651. In standard programming, input p6651 is wired to SIMOTION DCC.

Follow the steps suggested below to find out which i chart, block and input within the DCC-programming you have to use to start the “test mode” via DCC. To find the block of a chart which generates a signal fed to a BiCo-input, the I/O-variable and its assigned periphery address have to be identified first: - signal source to start the “test mode”:

A_INFMV_OM_G2 : r2095.1

- related to process data word PZD . . . . . / Bit . . . . . of object . . . . . . . . . . . . . . . . . . . . - identified by periphery address . . . . . . . . . . . . . . . . . . . . - related to I/O-variable . . . . . . . . . . . . . . . . . . . . . . . . . . . To locate chart and block to which this variable is connected, open any DCC-chart, select menu “Chart Reference Data” and a open the listing of “Cross Reference Chart Elements  Address”. Search for the variable in question and double click on it; the chart page showing this variable and its wiring to a DCC-block is opened automatically. Note down which chart, which block and which input you have to use to start a “test mode” via DCC: chart / page . . . . . . . . . . . / . . . . . . . . . .

3.5 Test Mode “Auxiliary Fan” Select test mode “Auxiliary Fan” and trigger the test via the assigned DCC-chart: the “Auxiliary Fan” installed in the SM150-rack is switched on and runs while the test mode is active. As an alternative to DCC the e test mode can be activated by any other input source belonging to the same drive device (Infeed) as well, i.e. by a digital input of a TMxx or via input simulation to a digital input of a TMxx. Refer to the wiring scheme of the terminal interface assigned to components =.2HC-A11 (DI/O 12) and =.2HD-A51 (DI/O 23) and assign a suitable input via the respective binector as input source: p6651_Infeed f = .... ................................... Activate test mode “auxiliary fan” by connecting the two measuring leads as substitute for a switch. Finally trigger the test mode also by simulating this digital input.

3.7 Test Mode “Line Breaker” (without medium voltage ! ) As this test will actuate the Line Breaker you have to make sure that NO VOLTAGE will be switched to the Infeed. Verify that the Line Breaker is withdrawn and in test-position before triggering test mode “Line Breaker”. At the training rack, switch o off the mcb to the left of contactor “TC-K41”; this condition simulates “Line Breaker in test position”. Parameters p6677 to p6680 have to be set in accordance with the Line Breaker used (commonly found Line Br eakers require a setting i as shown); parameters for the monitoring times can be set only after evaluation of switching operations (for an overview of Line Breaker configuration possibilities refer to “List Manual, page 9800”). Both, the control signals to the Line Breaker and t he feedback signals from the Line Breaker are directly wired to the CX32; verify that the wiring matches with the given reference (slide on ne xt page). The time properties of the Line Breaker will be identified by evaluating the status information of the terminals for the control and the feedback signals.

(NOTE: if the Line Breaker doesn’t close, check the information on the f ollowing page.) From the recording, read the delay time (“close” command to feedback “closed”): . . . . . . . ms Define the tracer to record a.m. signals when the “Open command” is given and initiate the “Open command”: the Line breaker switches off (at the training rack: contactor “TC-K1”) and the tracer records the assigned signals. From the recording, read the delay time (“open” command to feedback “open”): . . . . . . . ms (for the SM150 the “Open” delay time of the Line Breaker must be less than 80 ms). The time the circuit breaker takes to o pen is checked against the setting of the “maximum opening time (p6676)”. Set the “maximum opening time” to a value less than required (as just found out by measurement) and verify by a test that related error messages are generated. Finally set the “maximum opening time” back to a sufficiently large value, i.e. 100ms.

If the Line Breaker doesn’t close, an OFF2 command might be active in the control word for the Infeed. Check this status in DCC-chart AINF1, sheet F1,, block SAI100. This DCC-program is also used to individually allow an operation of one of several Infeeds in parallel configuration by assigning an OFF2 command n to the others. For training purposes, block Infeed 1 from responding to the “Line Breaker Close command”. After this test, enable Infeed 1 again.

3.8 Test Mode “Pre-charging” (without medium i voltage ! ) During this test DC-voltage up to the specified level (p6620) is generated on t he DC-link and on all components connected to it. Make sure that this test can be carried out without endangering personnel or equipment!

Switch on the cooling system (via Auxiliaries) e using the OP177 in “Local Mode” with key “K3/AUX ON”. Start with a small setpoint value for the DC-voltage, i.e. p6620 = 5 %, select test mode “Pre-charging” and trigger the test by using the available “hardware switch” wired to component TM15/Infeed, terminal DI/O23 : the DC-link voltage is controlled to an average value as set in p6620 by consecutive close-/ open-commands to the pre-charging contactor (at the training rack: contactor “TC-K41”). Increase the setpoint for the DC-link voltage in 5% steps to 15%; at this stage, trace the a.m. values and verify that the positive and negative DC-link voltages are symmetrical. PLEASE don’t set more than 15% at t he training rack, as this would cause a continuous ON/OFF of the Yaskawas which will overload the Yaskawa-internal pre-charging resistors.

3.11 Measurement of Phase Shift The “power voltage” at the ALM inputt will typically be phase shifted versus the voltage measured by the VSM. Value and polarity of the phase displacement (leading, lagging) have to be identified without doubt. On the basis of a known voltage system (phases L1 to L3 on the VSM) you should first make a “reference measurement” crosschecking the indication on your scope versus “theory” followed by the second step of identifying the phase shift between “power voltage at ALM input” and “reference voltage at VSM”. To gain experience use the “transformer box” and carry out the measurements as suggested. Follow the procedure listed below to make the FIRST MEASUREMENT, then the SECOND MEASUREMENT and finally do the lab work. -

select the same V/div for both channels, invert channel B, align the two tracks to the zero line with input = GND use an appropriate voltage divider to measure voltages outside the range of the scope connect the voltages you want to measure to channels A (L1) and B (L3) of the scope (via voltage divider if large) set both channels to DC-measurement and ADD the two channels; you then measure L1 + (-L3) = UL1L3 follow the same steps to measure the second phase-to-phase voltage (channels A2, B2) if you have to adapt the V/div for any of the measurements, always select the same setting for channels A and B and verify the zero line alignment

FIRST MEASUREMENT make the “reference measurement” to find out how your scope displays voltage U L2L1 versus UL3L2

SECOND MEASUREMENT make one “test measurement” to verify your scope reading versus the “theoretical expectation”; i.e. U L1L3 versus UL3N

If you should only have a 2-channel scope available, the voltage U L2L1 has to be measured using channels “A – B” with e.g. “line trigger”, followed by the measurement of voltage U L3L2 using the same channels “A – B” with identical trigger criteria. These two measurements then have to be “mentally” superposed to read the phase displacement. UL2L1

3.12 Line Side Offset Angle For the operation as “Active Line Module” (pulses enabled) the Infeed has to be programmed with the phase angle displacement between the “power voltage” l and the “reference voltage”; typical values will read 30 0, 150, 200 or 7.50 (an appropriate phase shift between the different Infeeds helps to reduce the line side harmonics). The definition of the offset angle has to be made “in rough” u by manual setting; fine-tuning (+/-10) is carried out by means of an “identification mode”. ” Using the equipment available, measure the phase angle displacement in test mode “Pre-Charging and Line Breaker” (with medium voltage, v , inverter pulses blocked). At the training rack sockets to pick up all re quired voltages are located on the upper left side of the rack. Phase angle displacement:

p6420 = . . . . . . . . . . . . .

Likewise the voltage fed to the VSM has to be programmed “in rough”. Measure the voltage. VSM supply voltage:

3.14 Actual Value Offset Compensation Verify that the “Actual Value Offset Compensation” is enabled (in an operating mode where voltage and current are definitely zero, the feedback values are measured and then automatically set as offset values). 3.15 Actual Raw Values (Infeed) Physical quantities of the Infeed available via parameters (r….) have been evaluated already. The “Raw Values” as read in on the PSA (from the AVT-Cs) are displayed in r6760 – r6763. With parameter p6770 a number of assignments of these values can be viewed (i.e. the a.m. offset value). Raw values are helpful to check an individual actual channel if in doubt about the correct indication of the value. While still in test mode “pre-charging and line breaker”, use the tracer to record the values of the positive and negative DC-link k voltage as “processed values” available on parameters r70[1], r70[2] and as “raw values” of the PSA. assignment of “raw values” via: p . . . . . . . . . . . = . . . . . . “raw values” U.DC.pos:

3.16 Identification Routines Similar to the “Test Modes” used in the previous v steps the SM150 also offers a number of “Identification Routines”. They help to identify and set data such as the fine-tuning values of the “displacement angle” and the “input voltage of the VSM”, the “Line Transformer u.k” or the “DC-link capacity”. Identification Routines are selected with p3410; the currently active Identification Routine is indicated in r6442. The commands “Infeed ON” and “Pulse Enable” ( start the identification) are activated via chart AINF1, sheet F1. After having sswitched c on the Infeed and after having selected the intended Identification Routine the pulses for the Infeed have to be enabled; the selected Identification Routine will then be activated and indicated in r6442. A small number of additional parameters may prove to be helpful (refer to the list above). Edit a “user defined parameter list” similar to the one above to have quick access to the parameters that might be needed in carrying out the Identification Routines.
