29 Operation
Startup and shutdown
To start the drive:
1. Turn the speed adjust potentiometer full counterclockwise
(CCW). If the speed adjust potentiometer is wired for
bidirectional operation, set the pot to its center of travel. If
the drive is following a voltage signal, set the voltage signal
to 0 VDC.
2. Apply AC line voltage.
3. Slowly advance the speed adjust potentiometer clockwise
(CW). If the drive is following a voltage signal, slowly
increase the voltage signal. The motor slowly accelerates as
the potentiometer is turned CW, or the voltage signal is
increased. Continue until the desired speed is reached.
4. Remove AC line voltage from the drive to coast the motor 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.
