C1802 Motor feedback data not valid

DOK-INDRV*-GEN-**VRS**-WA01-EN-P
LSA Control S.L. www.lsa-control.com comercial@lsa-control.com (+34) 960 62 43 01
Supported by Firmware Variant:
At the beginning of the automatic control loop setting (P-0-0162, C1800
Command Automatic control loop adjust) the motor parameters
• torque constant and
• device type current
are read from the encoder data memory.
Cause:
• One of above-mentioned data stored in encoder has a value equal to
or less than zero (<= 0) which would cause incorrect calculation of
controller parameters.
• Motor without encoder data memory
Remedy:
If known, write correct values back to encoder data memory or contact
Rexroth service department in order to get data valid for respective motor.
If it is impossible to correct parameter values in encoder data memory,
motor must be replaced!
