Error group 54
Violation of Safety conditions (only CMMP-AS-...-M3)
No.
Reaction
Message
Code
54-6
80B0h
SBC: Brake not released for > 24h
configurable
Cause
–
Error occurs when SBC is requested and the brake has not been
opened by the basic unit in the last 24 hours.
Measure
If the brake is actuated via the brake driver in the basic unit
[X6]: The brake must be energised at least once within 24 V
before the SBC request because the circuit breaker check can
only be performed when the brake is switched on (energised).
Only if brake control takes place via DOUT4x and an external
brake controller: Deactivate 24h monitoring in the SBC para
meters if the external brake controller allows this.
54-7
80B1h
SOS: SOS requested for > 24 h
configurable
Cause
–
If SOS is requested for more than 24 hours, the error is
triggered.
Measure
Terminate SOS occasionally; move axis once occasionally.
Error group 55
Measuring of actual value 1 (only CMMP-AS-...-M3)
No.

Message
Reaction
55-0
80C1h
No actual speed / position value available or standstill for > 24
h
configurable
Cause
–
Subsequent error when a position encoder fails.
–
Safety function SSF, SS1, SS2 or SOS requested and actual
speed value is not valid.
Measure
Check the function of the position encoder(s) (see following
error).
55-1
80C2h
SINCOS encoder [X2B] - signal error
configurable
Cause
–
Vector length sin²+cos² is outside the permissible range.
–
The amplitude of one of the two signals is outside the permiss
ible range.
–
Offset between analogue and digital signal is greater than 1
quadrant.
Measure
Error may occur with SIN/COS and Hiperface encoders.
Check the position encoder.
Check the connection wiring (broken wire, short between two
signals or signal / screening).
Check the supply voltage for the position encoder.
Check the motor cable / screening on motor and drive side
EMC problems may trigger the error.
