Issue:
Altivar Process Drive power up with Safe Torque Off on the display

Product Line:
ATV

Environment:
All

Cause:
Wiring

Resolution:
The VFD safety feature requires 24Vdc input on STOA and STOB terminals.  If there is no field wiring to these terminals, you must leave or install a jumper from 24v to STOA / STOB on top of the drive in the CN2 position.
