Acknowledgement POWER ON
Stop response
STOP II (SRM, SLM) STOP I (ARM)
728
Torque/current adaptation factor too high
Cause
The adaptation factor between the setpoint torque and the torque gen-
erating current (Iq) in the speed controller is too high.
Remedy
Check P1103, P1107 and P1113 and if required, enter correct values.
Third-party motor:
The values should be determined from a motor data sheet.
Siemens motor:
The values are determined from the motor code (P1102).
Acknowledgement POWER ON
Stop response
STOP II (SRM, SLM) STOP I (ARM)

Cause
The rated motor output (P1130) of the motor is less than or equal to
zero.
Remedy
Determine the rated motor output of the motor used and enter in
P1130.
Third-party motor:
The rated motor output should be determined from a motor data sheet.
Siemens motor:
