*Use a jumper, between Terminals "5" and "8", if a Start/Stop Switch or Contact is not
required.
BIDIRECTIONAL OPERATION WITH START/STOP (Use Analog Input "1" Only)
Connect the potentiometer to Terminals "9" (+5 Volts), "19" (Analog Input 1), and "10" (-5 Volts). Connect the
Start/Stop Switch or Contact to Terminal "5", which is factory set for N.O. Start ("0010"), and to any available
common terminal ("8", "12", "14", "16", "18", "20", "22"). See Table 29, for drive programming. See Figure 37,
for connections.
Operation: Close the Start/Stop Switch or contact to start the drive. At 50% rotation, the potentiometer is set
for zero speed. Rotating the potentiometer clockwise will increase motor frequency in the forward direction.
Rotating the potentiometer counterclockwise will increase motor frequency in the reverse direction. Open the
Start/Stop Switch or Contact to stop the drive.
