MM-PCM Series
Connect an inhibit switch as shown in Figure 8A or 8B. Activating the
inhibit circuit causes the motor to coast to a stop. Deactivating the inhibit
circuit accelerates the motor to set speed at a rate controlled by the
ACCEL trim pot.
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.
