Inverter not sensing DC
We have acs 800 multidrive system.
There is FWD and reverse TSU installed. TSU is generating DC and it is reaching the inverters but the inverter is not sensing the DC voltage. We have checked AINT card also we have installed new asfc, apbu card but problem is still the same.
Can anyone help for this problem

How you know not sensing DC voltage ?
Check once NRED Card.

Sir,
If you replace spare AINT,AGDR with new connectors.
