Startup
To start the drive:
1. Turn the speed adjust potentiometer full counterclockwise
(CCW). If the drive is following a voltage or current signal,
set the signal to zero.
2. Apply AC line voltage.
3. Slowly advance the speed adjust potentiometer clockwise
(CW), or slowly increase the reference signal. The motor
slowly accelerates as the potentiometer is turned CW, or the
signal is increased. Continue until the desired speed is
reached.
4. Set the speed adjust potentiometer to zero, remove AC line
voltage, or set the input signal to zero. The drive will coast
to a stop.
If the motor or drive does not perform as described, disconnect
the AC line voltage immediately. Refer to the Troubleshooting
section for further assistance.
