1003: Parameter cannot be written while loop control is active

Description:
Response error while writing a parameter, which does not allow a change in the value when the controller is active.

Reaction:
The parameter value is not accepted.

Cause/Remedy:
The parameter was written too late (after the 'switch on controller' command).
The 'switch off controller' command is missing or was not executed in the drive state (movement active).
Request (delay step) for 'controller off' state is missing.
-> Check program sequence and status request.
