Drive Enable 2 LCD will display "dnE".
The drive will run when the Run and Drive Enable2 inputs are both closed. If the
Drive Enable2 input is opened while the drive is running, the drive will stop using
the method set by parameter b1-03.

The functionality is identical to Drive Enable 2 (H1-oo = 70), except for the

is present. It will not display "dnE".
Open: Customer Safeties are open. Drive will not run. Stopping method is Coast
to Stop.
Closed: Customer Safeties are in place.

drive displays an "inTLK" message if a Run command is present. It will not display

Description
This multi-function input has no effect on the secondary PI
controller. It is only used for the primary PID controller (b5-oo).
The state of the BAS Interlock multi-function input has no effect on
the Emergency Override multi-function inputs (H1-oo = AF, B0).
The Emergency Override command is accepted when the BAS
Interlock digital input is open or closed.
