Meaning of the error message
Action: Check when the violation of the safety condition
occurs:
c) During dynamic braking to zero.
d) After the drive has reached zero speed.
With a) Check of braking ramp – record
measuring data - can the drive follow the ramp?
Change parameters for the slowdown ramp or
start time / delay times for monitoring.
With a) If the option “Trigger basic device quick
stop” is activated: Check of the basic device’s
quick stop ramp.
With b) Check whether the drive continues to
oscillate after reaching the zero speed or remains
at idle and stable –
increase monitoring tolerance
time if necessary.
With b) If the actual speed value is very noisy at
rest. Check and if necessary adjust expert
parameters for speed recording and detection of
idling
3 SOS: Safety Condition Violated Cause: Angle encoder analysis reports “Motor running”
(actual speed exceeds limit).
Drive has rotated out of its position since
reaching the safe state.
Action: Check the 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
idling.
4 SS1: Safety Condition Violated Cause: Actual speed is outside of
long.
