: The output frequency for reverse rotation is 10 Hz.
: Set the acceleration time to 10 seconds.
: Set the deceleration time to 10 seconds.
: Accelerate the forward rotation speed up to 60 Hz.
: Wait until the motor operates at 60 Hz.
: Start the 15-second timer counter.
: Turn the FW terminal off after 15 seconds elapse.
: Wait until the motor stops.
: Start reverse rotation after 1 second elapses.
: Accelerate the reverse rotation speed up to 10 Hz.
: Wait until the output frequency reaches 10 Hz.
: Decelerate and stop the motor.
: Wait until the motor stops.
