Regular Checks
A regular check is intended only to demonstrate that the STO is functional. It will not always detect the loss
of a single channel, so it is therefore important for the user and/or machinery builder to determine the
frequency of the comprehensive checks based on their knowledge and application of the machine.
A regular check is recommended once per week.
Where a regular check coincides with the timing of a comprehensive check, the comprehensive check must
take precedence.
The following steps must be performed and recorded during a regular check:
STO Test
Step Test Check or Activity Expected Reaction & Effect
1
Firstly, ensure that no harm can come to
personnel or equipment if the motor turns.
None.
2
Apply +24Vdc to the inverter control board
terminals STOA and STOB, and 0V to the
STO 0V terminal.
None.
3
Switch on power to the inverter.
No error must be present in the drive
system.
4
Try to start the inverter with a non-zero
setpoint. This setpoint value will be referred
to as SPT1 for brevity in these tests. Leave
this set throughout all tests.
Inverter must start and the motor must turn
at SPT1.
5
With the inverter running and the motor
turning at SPT1, disconnect terminal STOA
and STOB within 1 second of one another.
Leave both disconnected for approximately
5 seconds.
Motor must immediately coast to a rest.
Inverter must report a STO trip immediately.
