C235 Load-side motor encoder with inductance motor only
Cause:
The functionality of the optional encoder can be defined in the P-0-0185,
Function of opt. encoder parameter. If ’load-side motor encoder’ has
been selected as the function of the optional 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 opt. encoder parameter.
See also the functional description: "S-0-0128, C200 Communication
phase 4 transition check".
C236 Feedback 1 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 opt. 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 optional
encoder.
Enter a value
≠
0 in the P-0-0074, Interface feedback 1 parameter to
activate the motor encoder.

phase 4 transition check".
C238 Wrong function of encoder 2
Cause:
An operating mode needs encoder 2 as control encoder.
Encoder 2 is, however, being used as master axis encoder or measuring
wheel encoder.
Recovery:
1. Only operating modes with motor encoder in the operating mode
parameter S-0-0032, S-0-0033, S-0-0034, S-0-0035, have been
entered.
2. If a mode needs encoder 2 for control, then encoder 2 must be
used as control encoder or spindle encoder. (P-0-0185 =0 or 4).
C300 Command Set absolute measuring
Command P-0-0012, C300 Command ’Set absolute measurement’ was
activated by the control system in use.
