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
