Operation

Inhibit terminals

Short the INHIBIT terminals to coast the motor to minimum speed
(see Figure 15 for INHIBIT terminal location). Open the INHIBIT
terminals to accelerate the motor to set speed.

Twist inhibit wires and separate them from power-carrying wires or
sources of electrical noise. Use shielded cable if the inhibit wires
are longer than 18 inches (46 cm). If shielded cable is used,
ground only one end of the shield to earth ground. Do not ground
both ends of the shield.

Minarik Corporation offers two accessory plug harnesses for
connecting to the INHIBIT terminals: part number 201-0024 [inhibit
plug with 18 inches (46 cm) leads]; and part number 
201-0079 [inhibit plug with 36 inches (91 cm) leads].
