Aux Interlock Enable Parameter 21 -- Auxiliary Interlock

Units = Code

Range = 0/1

Factory

Setting

To enable drive operation, terminal 16 and logic common at the Control

and Signal Wiring Terminal Block must be jumpered. This parameter sets

the function of terminal 16 and logic common when a normally closed

auxiliary interlock is installed in its place.

If set to 0, when the auxiliary contact opens:

• The drive will coast-to-stop, display fault

AU, and store the fault in

Fault Buffer Parameters 59-62.

• Fault Contact CR3 on the Control Board will change state to provide a

fault signal at terminals 22-24 at the Control and Signal Wiring Terminal

Block.

If set to 1, when the auxiliary contact opens:

• The drive will coast-to-stop and display

AS. Since AS is not a fault, it

will not be stored in Fault Buffer Parameters 59-62.

• Since

AS is not a fault, Fault Contact CR3 on the Control Board will not

change state to provide a fault signal at terminals 22-24.
