Possible causes
Analog input calibration: calibration: Automatic Automatic calibration calibration of analog calibration of analog inputs was not inputs could not be carried out successful. successfully because one of the analog input values is higher than 0.5 mA.
Hints for rectification
Fault class ARU
Fault class INU
Analog input wires have to be disconnected for the calibration. Retry calibration.

Defective IOEC.
Aut oRest art
Drive trip because auto-restart sequence takes too long.
Depends on the fault that initiated the auto-restart sequence.
The auto-restart function function is enabled with P31.01.
Wrong parameter setting
Check reason for auto restart attempts. Check related parameters.

Possible causes
Brg DE Mlos
Motor bearing temperature Loss of measurement signal. measurement at driven end: loss of analog input. Defective temperature probe.
Hints for rectification
Check measurement circuit, refer to the electrical diagram for terminal identification. Check components and wiring.
Motor bearing temperature is a 4...20 mA analog input signal. BrgDE Mlos alarm is activated when measuring signal drops below 2 mA. Connection: AI02-IOEC3 (X31.3, X32.3) (IOEC3 has to be activated by setting P75.01 to YES). Actual bearing temperature temperature can be read from P80.02 BEARING TEMP DE (via AI02-IOEC3). Measurement loss detection is activated only if P81.10 AI2 MINIMUM IO3 is set to 1 (1 = 4 mA / 2 V). Reaction to measurement loss can be set to NONE, ALARM or SOFT STOP with P35.01 BEARING BEARING TEMP PROTECTION DE.
Faulty components or wiring. Check parameter settings. Communication problem with IOEC3.
Check the analog inputs on IOEC3. Check IOEC3 DIP-switch setting according to wiring diagram.
