Meaning of the error message
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
when at rest: Check and if necessary adjust
expert parameters for speed recording and
detection of standstill.
5 STO: Safety Condition Violated Cause: Internal hardware error (voltage error) of the
safety module.
Action: Module presumably defective. If possible,
replace with another module.
Cause: Error in driver circuit section in the basic device.
Action: Basic device presumably defective. If possible,
replace with another basic device.
Cause: No feedback received from basic device to
indicate that output stage was switched off.
