Installation
Speed adjust potentiometer connections
The motor can operate in one direction (unidirectional) or in two
directions (bidirectional) depending on how the speed adjust
potentiometer is connected to the drive.
Connect the speed adjust potentiometer as shown in Figure
8(a) for speed control in one direction.
Connect the speed adjust potentiometer as shown in Figure
8(b) for speed control in two directions. The motor does not
rotate when the wiper is in the center position. Turning the
wiper CW from the center position causes the motor to rotate in
one direction, while turning the wiper CCW from the center
position causes the motor to rotate in the opposite direction.
Refer to the Application Notes section (page 37) for additional
speed adjust potentiometer connections.
