7
SOS: SOS requested > 24 hrs
Cause: If SOS is requested for more than 24
hours, the error is triggered.
Action:
Terminate SOS and move axle at least
once during this time.
55
0
No actual rotational speed /
position value available or idle >
24 hrs
Cause:
Subsequent error when a position
encoder fails.
Safety function SSF, SS1, SS2 or
SOS requested and actual
rotational speed value is not valid.
Action:
Check the function of the position
encoder(s) (see following error).
1
SINCOS encoder [X2B] -
Tracking signal error
Cause:
Vector length sin²+cos² is outside
the permissible range.
The amplitude of one of the two
signals is outside the permissible
range.
Offset between analogue and digital
signal is greater than 1 quadrant.
Action:
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
malfunctions may trigger the error.
2
SINCOS encoder [X2B] -
Standstill > 24 hrs
Cause: Input signals of the SinCos encoder
have not changed by a minimum
amount for 24 hours (when safety
function is requested).
Action:
Terminate SS2 or SOS and move axle
at least once during this time.
