Action:
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) 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

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.

SS1: Safety Condition Violated
Cause:
Actual speed is outside of permitted limits for too
long.
