How to check the Logic inputs on an ATV312 drive?

Published date: 24 July 2020

How can the Logic inputs be verified for proper function on an ATV312 drive?

Product line:
ATV312, Altivar 312


Drive is not responding to run Command or other logic inputs.

Go to the Monitor menu (SUP), then Logic Input Conf (LIA-).  Scroll down to LIS.  Not LI5A, just LIS.  Push enter and you will see 6 hash marks which represent LI1 thru LI6.

If the input is closed, the hash mark will be up.  If open, the hash mark will be down.  You can test the inputs by using a jumper wire from 24V to any Logic Inputs to see if they change state.
