Action
Test the operation of the STO function when the motor is stopped.
• 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).
• Give a start command to verify that the STO function blocks the drive's operation. The
drive generates a warning. The motor should not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
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 (wire coming to IN1). If the motor was running,
it should coast to a stop. The drive generates a
FA81 Safe Torque Off 1 loss
fault indic-
ation (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 (wire coming to IN2). If the motor was running,
it should coast to a stop. The drive generates a
FA82 Safe Torque Off 2 loss
fault indic-
ation (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 for operation.
