Hello everyone,

I would like to individually control 8 Brushless DC motors with the S7-1200 1214C DC/DC/DC. I want to use these motors to tighten 8 knobs to a certain torque. They have 8 count hall effect sensors.

Does anyone know if this task feasible with the 1214C? I've read that I can control 4 drivers/motors with PWM. Is there any way that I can control 8? Is torque control possible?

Please let me know if you need any more information.

Thank you

Hello,

If you use vfd, you can monitor torque as feedback of vfd, then make control that in program, but maybe there is a more precise way such a torque sensor that I don't know. 

New question published by Larry808 is split to a separate thread with the subject Which specific motor driver is compatible with the 1214C.?.
