Error group 54
Violation of Safety conditions (only CMMP-AS-...-M3)
No.
Reaction
Message
Code
54-3
80ADh
SOS: Safety condition violated
configurable
Cause
–
Angle encoder evaluation reports "Motor running" (actual
speed exceeds limit).
–
Drive has rotated out of its position since reaching the safe
state.
Measure
Check position tolerance for the SOS monitoring and increase if
necessary, if this is permissible.
If the actual speed value is very noisy when at rest: Check and if
necessary adjust expert parameters for speed recording and
detection of standstill.
54-4
80AEh
SS1: Safety condition violated
configurable
Cause
–
Actual speed outside permitted limits for too long.
Measure
Check when the violation of the safety condition occurs:
a) During dynamic braking to zero.
b) After the drive has reached zero speed.
With a) Critical check of braking ramp record trace - can the
drive follow the ramp? Change parameters for the braking ramp
or start time / delay times for monitoring.
With a) If the option "Trigger basic unit quick stop" is activated:
Critical check of the basic unit's quick stop ramp.
With b) Check whether the drive continues to oscillate after
reaching the zero speed or remains still and stable increase
monitoring tolerance time if necessary.
With b) If the actual speed value is very noisy when at rest:
Check and if necessary adjust expert parameters for speed
recording and detection of standstill.

80AFh
STO: Safety condition violated
configurable
Cause
–
Internal hardware error (voltage error) of the safety module.
Measure
Module presumably defective. If possible, replace with another
module.
Cause
–
Error in driver circuit section in the basic unit.
Measure
Module presumably defective. If possible, replace with another
basic unit.
Cause
–
No feedback received from basic unit to indicate that output
stage was switched off.
Measure
Check whether the error can be acknowledged and whether it
occurs again upon a new STO request if yes: basic unit is pre
sumably faulty. If possible, replace with another basic unit.
