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).
• Open the STO circuit (both channels).
• Give a reset command.
• Close the STO circuit (both channels).
• Reset any active faults.
• Open the 2nd input channel of the STO circuit. If the motor was running, it should coast to a
