tCt

Defines the type of 2-wire control: LEL-TrN-

PFW

LEL

• LEL: If the forward or reverse input is high when the drive

controller is powered up, the drive controller will start the

motor. If both inputs are high on power up, the controller will

run forward.

• TrN: The drive controller must see a transition from low to high

of the forward or reverse input before it will start the motor.

Therefore, if the forward or reverse input is high when the drive

controller is powered up, the input must be cycled before the

drive controller will start the motor.

• PFW: Forward input has priority over reverse input with this

control. If forward is activated while the controller is running in

reverse, the controller will run forward.

2-wire control wiring example:

RV inhibit

rln

When configured for Yes, this function

inhibits reverse operation even if

Yes - No No

reverse operation is requested by a summing or PI regulator

function. This parameter is not available if a logic input is

configured for reverse. A logic input cannot be configured for

reverse if this parameter is configured for Yes.

NOTE: Type 2

Wire appears if

2-wire control is

selected.
