About torque control

[hyg-1982]

Hi,I I have a IMAC400 applied to a load torque project.The project is implement a load torque device(Referred to as LTD),including IMAC400,Motor drive,Torque sensor and Torque Motor.The idea of control as follows:The LTD provide a torque for UUT,Torque load data is angle and torque corresponding relationship .When the UUT lead LTD to a rotation angle, TLD according to torque data output torque .

My question is as follows:

1.How the torque sensor signal into the IMAC400, the formation of closed-loop torque;

2.When the torque sensor achieve to motor close-loop,how to set up the ECT;

Thanks!

If you need to cascade both a position loop and a torque loop, one for each of your sensors, you need to implement a "Cascaded Servo Loop" technique as described on page 163 of the Turbo PMAC User Manual.
