B203 Brake torque too low
The motor moved when checking the brake torque during the command
monitor brake. The motor holding brake thus does not supply the nominal
torque.
Possible causes for the low holding torque:
1. Brake covered by oxidized layer due to storage
2. Brake covered by oil or lubricant
3. Brake is worn down.
Remedy on:
1. Re-start "command brake monitor".
2. Re-start "command brake monitor". The command brake monitor re-
checks the brake torque again. If detected that the torque is too low,
then the brake is bedded in. The bedding of the brake removes the
oxidized layer or oil film. The brake should now be able to generate
sufficient torque.
3. If multiple tries result in the brake still not reaching the holding torque,
then the motor holding brake has to be replaced.

Cause:
Communications parameters which are needed to operate the drive in
communication phase 3 are invalid.
Remedy:
A list of the invalid parameters can be seen in parameter S-0-0021, List
of invalid op. data for comm. ph. 2. The invalid parameters must be
rewritten so they are correct.

C102 Limit error communication parameter (S-0-0021)
Cause:
Communications parameters, which are needed to operate the drive in
communication phase 3, are outside their limit values.
