Issue:
Can you run multiple motors with one ATV320 drive?
 
Product Line:
ATV320
 
Environment:
Operating multiple motors simultaneously
 
Cause:
Documentation

Resolution:

Yes, but you need to size the drive according to the sum of the HP and max current of all the motors and provide separate overload protection for each motor.
All motors will will start/stop at the same time and run at the same speed.
