I have a 1.5Kw servo with its drive. The drive has RS232 port , but the Chinese maker says it is for config only. I need to vary the speed of this servo based on a feed back , closed loop control. As from the documentation the only way to vary the speed at run time is by changing the voltage applied to a pin. That pin can accept -10 to +10V so that it will change its speed from max anticlockwise to max clockwise.
Please confirm weather my understanding is correct as the general case with servo drives!
Considering that the only possible way available to vary speed is by changing the voltage in a control pin, which is the ideal method to do this from a PIC MCU. Digital potentiometer chip I have tried but not giving enough resolution.
Please suggest!
