Can you describe the machine environment in which you're homing?  Need to know if your servo has a absolute or incremental encoder also.

We are controlling position with the  Mitsubishi servo (MR-JE20A) using Allen Bradley micrologix 1400 PLC with PTO instruction . Just don’t know how to set zero position  for the servo . How to set home position?

sounds like it is hardwired.  You should be able to define an input on the Servo to trigger the homing.  Then define an output from the ML1400 with a rung of code to turn on the output.  Back in the Servo, you'll need to define how it's going to perform the homing and upon completion, set the encoder value to zero.
