Type 2 Wire 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 reverse

operation is requested by a

summing or PI regulator

function.

Yes - No No

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.

★ These I/O can be accessed if an I/O extension card has been installed.
