Volts DC). If the MIN

Trimpot is set to other

than 0 Volts DC, the

motor will run at that

speed when the

switch or contact is

opened. An open col-

lector (PNP) can be

wired in lieu of a

switch or contact.

Note: The decelera-

tion time can only be

made longer than the

normal coasting time

of the load.

6.8 Inhibit Circuit Connection – The control can be stopped

and started with an Inhibit circuit (close to stop, open to run).

Wire the switch or contact to Terminals “I1” and “I2”, as

shown in Figure 7. When the switch or contact is closed, the

motor will coast to stop. When the switch or contact is

opened, the motor will accelerate to the Main Speed

Potentiometer setting. An open collector (NPN) can be wired

in lieu of a switch or contact.

WARNING! The Inhibit Circuit is never to be used

as a Safety Disconnect since it is not fail-safe. Use

only the AC line for this purpose.
