FIM2360, operation mode of motor was created by Active Process
My question is, can I use the mode Closed Loop Position Relative with this controller?. Because I want do a position control for steering wheel, but I don’t see the option in Robotrun+.
How can I solution for this problem?

Thanks for any anwer

A closed loop position mode has not been implemented in the AC induction controller yet. For now, you will have to set up a Position controller in MicroBasic.

I don’t understand about set up a Position controller in MicroBasic. I have to use other controller and this controller is of position? And connected to FIM2360 controller?.

I understand, I have to use the scripting, right?. And you have an example code for guide me about this control.

Thank for you help.

Sorry about the late response,

Unfortuantely, we don't have a position control example for AC induction. AC induction motors are generally poor for position control because their torque output at low RPM is very poor compared to BLDC or PMAC motors. We also require a very high level of motor characterization to operate in a mode where you are controlling torque on the motor directly.

We use a position controller to control steering in our AGV application note . You should be able to adapt the steering controller from that example to control rotor position instead.

Thanks for you answer, I solved the problem with a code in scripting.
But I have other problem, the traction motor don’t work when the scripting is working. I checked and find that the cause are the command priorities. The traccion motor is set up for analog command and FOC control.
How can I solve this problem?
Can I edit the scripting for allow the traction motor work with analog command and FOC control?

Scripting commands operate on the serial priority. Just make sure priority #1 is set to serial.

Thank you for you answer, but the priority #1 is set to serial and priority #2 is set to analog.

I want to make work the two motors at the same time, a motor with the steering wheel in scripting and the other motor with FOC control, but only work a motor.
How do I solve this problem?, because I tested activating the scripting for steering wheel for motor 2, and set up with RoboRun + for motor 1 the FOC control and analog command, with priorities # 1-serial and # 2-Analog. But the motor 1 do not work, only the motor 2 is working.
