Action
Test the operation of the STO function when the motor is running.
• Start the drive and make sure the motor is running.
• Open the STO circuit. The motor should stop. The drive generates an indication if one is defined for
the 'running' state in parameter
31.22
(see the firmware manual).
• Reset any active faults and try to start the drive.
• Make sure that the motor stays at a standstill and the drive operates as described above in testing
the operation when the motor is stopped.
• 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 channel of the STO circuit. If the motor was running, it should coast to a stop. The
drive generates a
FA81 Safe Torque Off 1 loss
fault indication (see the firmware manual).
• Give a start command to verify that the STO function blocks the drive's operation. The motor should
not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
• Open the 2nd channel of the STO circuit. If the motor was running, it should coast to a stop. The
drive generates a
FA82 Safe Torque Off 2 loss
fault indication (see the firmware manual).
• Give a start command to verify that the STO function blocks the drive's operation. The motor should
not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
Document and sign the acceptance test report which verifies that the safety function is safe and accepted
