Remedy:
Select another external encoder.

C235 Load-side motor encoder with inductance motor only
Cause:
The functionality of the external encoder can be defined in the P-0-0185, Function of ext. encoder parameter. If 'load-side motor encoder' has been selected as the function of the external encoder, that function will only be supported for asynchronous motors.
Remedy:
Set the P-0-4014, Motor type parameter according to the employed motor type.
Check the P-0-0185, Function of ext. encoder parameter.

C236 Motor feedback required (P-0-0074)
Cause:
A motor encoder is not required (P-0-0074 = 0) if a load-sided motor encoder has been selected via the P-0-0185, Function of ext. encoder parameter. However, S-0-0147, Homing parameter or the S-0-0032...35, Mode of Operation parameters contain values that require a motor encoder.
Remedy:
Change S-0-0147, Homing parameter or the S-0-0032...35, Mode of Operation parameters such that they are suitable for using an external encoder. Enter a value ¹ 0 in the P-0-0074, Interface feedback 1 parameter to activate the motor encoder.

Remedy:
End the command and turn off the drive enable, then the command can be started from the beginning.

C402 Only allowed without Master
Cause:
The command P-0-4023, C400 Communication phase 2 transition was started via the serial interface. The command is not executed and terminated with this error message because the active SERCOS interface is of a higher priority and was disturbed. The command can only be executed if the SERCOS interface is inactive (i.e. there are no signals applied to the receiver of the SERCOS interface).
Remedy:
Perform phase selection via SERCOS interface or de-activate SERCOS interface before the command is started.
