Servo motor follows encoder

[notepad]

Hi,
I have a synchronising problem. I got a incremental encoder that is connected directly into the servo driver. I'm suppose to turn the encoder shaft. When the encoder shaft turns for 90 degrees, the servo motor shaft will follow instantly and turns for 90 degrees in the same direction as the encoder shaft. Anyone knows how to do it? Can it be done?

Servo drivers have position control mode. In position control mode, you can connect outputs (A,B pulses) of the encoder to them and setup servo driver to follow these pulses. If you use DELTA SERVO, I can help you.

unfortunately without open source code . But you can buy it .
