I have a Yaskawa servo motor SGMSH-20DCA6F. Its key way had damaged so I tried to replace with another Rotor of same servo by installing the previous OK encoder. As I power on the machine after some steps servo gives the error.
Can anybody suggests me how to align the encoder with servo motor?

This is the BEST that can be done. Servomotors are only serviceable by the manufacturer's shop, but it's usually cheaper to get a new one. Do not expect to disassemble one of these and get it to work. In other words, servomotors are disposable most of the time.
