54 0 SBC: Safety Condition Violated Cause: Brake should engage; no feedback
received within the expected time.
Action:
Check how the feedback signal is
configured – was the correct input
selected for the feedback signal?
Does the feedback signal have the
correct polarity?
Check whether the feedback signal
is actually switching.
Is the parameterised time delay for
the analysis of the feedback signal
appropriate to the brake used
(measure switching time if
necessary)?
2 SS2: Safety Condition Violated Cause: Actual speed outside permitted limits
for too long.
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
