WARNING!
Obey the safety instructions. If you ignore them, injury or death, or damage to the equip-
ment can occur.
Test the operation of the STO function. If the motor is running, it will stop during the test.
• Give a stop command for the drive (if running) and wait until the motor shaft is at a standstill.
Make sure that the drive operates as follows:
• Open the STO circuit. The drive generates an indication if one is defined for the 'stopped'
state in parameter 31.22 (see the firmware manual).
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
Test the operation of the failure detection of the drive. The motor can be stopped or running.
• Open the 1st input channel of the STO circuit. If the motor was running, it should coast to a
stop. The drive generates an FA81 fault indication (see the firmware manual).
• Close the STO circuit.
• Reset any active faults.
• Open the 2nd input channel of the STO circuit. If the motor was running, it should coast to a
stop. The drive generates an FA82 fault indication (see the firmware manual).
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
Document and sign the test report to verify that the safety function has been tested according
to the procedure.
