Issue:
How can I wire a 3 wire start/stop push buttons to an Altivar 660 and 960 process system drive with hand off auto controls?

Product Line:
 Altivar 660 and 960 Process Drive System

Environment:
All serial numbers for Altviar 660 and 960 drives

Cause:
N/A

Resolution:
The drive comes with various controls options which includes a Hand-Off-Auto with or without a Start/Stop Push Button for Hand control.  
There is not an option for a 3 wire control for auto mode.

The best way to connect would be to bring in your own latching relay off an interposing relay on your external controls then use a set of
normally open dry contacts off that same relay back to the drives Auto Mode Start Contacts on terminals 3 and 4.
