15.1.18 Calibration
Causes and remedy:
An error has occurred during the calibration of the synchronous machine.
Consult RST.
15.1.19 Earth fault
Triggered:
The measured earth fault current exceeds the permissible value.
Causes and remedy:
High EMC impact.
Motor defective.
Check shields and RC-elements of contactors.
Check if large interference sources (e.g. large machines, …) are located near the converter.
Measure motor.
15.1.20 Motor overload
Triggered:
The load limit of the motor was exceeded.
Causes and remedy:
Wrong parameterisation.
Incremental encoder defective.
Motor possibly too small.
Check parameterisation.
Consult RST.
15.1.21 Sine amplitude
Triggered:
Amplitude of sine signals is outside of permissible range.
Causes and remedy:
sine encoder defective
Wrong D-SUB connector configuration, or connector not plugged.
Check sine encoder wiring.
Consult RST.
15.1.22 CDAmplitude
Triggered:
Amplitude of CD-Signale (encoder ERN1387) outside of tolerance range.
Causes and remedy:
Sine encoder defective.
Wrong D-SUB connector configuration or connector not plugged.
Check sine encoder wiring.
Consult RST.
15.1.23 Referencing error
Triggered:
In the case of CD encoder, if no zero pulse was found after 60 s of travel.
Causes and remedy:
Consult RST.
