How do I set up an AC10 for torque control?

Although torque control on the AC10 is certainly possible in Sensorless Vector mode, its primary functionality is to be used in velocity-type applications with torque compensation rather than direct control.

For Sensorless Vector torque control (of AC induction motors) we advise using the 690+, 890 drives, or AC30 drives. More information can be found on this FAQ site under their respective sections in the sidebar, or on their respective product pages on Parker.com.

If you think you have a volume application that requires an AC10 in torque control please contact your local Parker ATC, or Parker Applications for advisement.

Equipment needed: AC10 drive, AC10 Manual

Procedure:

• Control Mode MUST be set for Sensorless Vector for Torque Control

1. Set AC10 parameters as follows.
   
   

   Parameter	Description	Setting Range	Default
   F106	Control Mode	0: Sensorless Vector 1: Reserved 2: VVVF (V/Hz) Vector Control 1	2
   F228	Application Selection	0: Invalid 1: Basic Speed Control 2: Auto/Manual Control 3: Stage Speed Control 4: Terminal Control 5: PID Control	0
   FC00	Speed/Torque Control	0: Speed Control 1: Torque Control 2: Terminal Switchover	0
   FC06	Torque Given Channel (Torque Command Source)	0: Digital Given (FC09) 1: Analog Input 1 2: Analog Input 2	0
   FC07	Torque Given Coefficient (Torque Command Scaling)	0.1 (Start here and adjust upward as required)	3.000
   FC06	Torque Offset Channel (Torque Offset Source)	0: Digital Given (FC17) 1: Analog Input 1 2: Analog Input 2	0
   FC07	Torque Offset Coefficient (Torque Offset Scaling)	0.5	0.500
   FC17	Torque Offset	0	10.00

2. Ensure required motor information and I/O setup for your application is followed. (Is there an enable, an external fault, etc etc).
3. Perform a rotating autotune on the connected motor for Sensorless Vector mode.
