Hello ,

I have read in this forum that the motor controller does have a pid .But it's not very adéquat since it have to be configurated manually.
Is it possible to implemente the pid algorithm on a PLC or a microcontroller and send it back to the controller?
If yes , please can you explain more the process ?
In fact I'm going to use the motor controller with the magnetic sensor to detect a magnetic tape.So i need a pid to adjust the position and a pid to adjust the speed . Thanks!

Hello,

If you want to use closed loop speed, there is built-in PID system, all you have to do is to set the Proportional, Integral and Differrential values. This configuration is simple you can start with some initial values and then do some tuning.

If you want to implement it in another side you can do it and then send the appropriate command to the controller. The motor command can be given either as a pulse, an analog signal, an encoder input, via CAN, RS232 or USB. It is up to you to choose what fits better to your requirements.

Hello ,
Thanks for the reply.
So if i get it right.I will have to read the magnetic sensor with the controller, then send the position to the plc which will make the calculation to estimate the PID .Then the PLC will send via rs 232 the new speed with the commande !G 1 x ! G 2 y where x and y are variable send via the plc .

This is it ?

If so , what kind of information do the magnetic sensor send so that the plc can regulate the robot position?

Thanks
