Hello,

I would like to use PWM which will be controlled by my own PID-controller to regulate te current flowing to my DC gearmotor.
Is this possible or will it always use the maximum current the motor is asking for and only regulate the Voltage?

Thanks for reading 🙂

nevermind, i fear i hadn't really thought it through.
The current a motor pulls is dependant on the voltage is gets at a specific load if i'm correct. So by regulating the voltage to the engine i'd effectively be regulating the Current it receives? if that's correct?

Hi @filliersa,

If you are using SOLO, you don't need to do any of these, if you put SOLO in Torque Mode while DC brushed motors are utilized, SOLO will control the current of your DC motor with internally built-in PI controllers, you just need to set the desired value and the "IM" parameter in Motion terminal monitoring section will show you the amount of current in your motor in terms of Amps.

The Torque control on DC brushed motors with SOLO is done in a sensorless manner, so there will no need to have any type of sensors like Encoders.

This is correct in all the Voltage Source Inverters (VSI) including SOLO.

Let me know if you have other questions.
