Hello all.
Mori NL1500
Mitsubishi controls
MSX-850

The alarm on the screen is EMG Emergency Line
The fault code on the drive is "b". (See pic).

I was getting ALM 32 X alarms. We unwired the motor from the drive, and got ALM 51 X alarms. Swapped servo drive, these faults cleared.
I only get the EMG fault above.

Any ideas?
