Srinivas,
This method may work, however, keep in mind that PMAC is designed to do a complete position and velocity PID loop and disabling fatal following error, is considered very dangerous. If you do have true feedback from the motor, I would suggest using it for both position and velocity of motor 1. Tune the motor 1 in position mode. Once you integrate your analog input in ECT and bring in the result as master position for motor 1, it would act as if it was velocity control, but with much better safety.

Dear sina
Thanks for your valuable feedback........
Can you tell me what is the difference between Ixx67 and Ixx11 (and/or Ixx12) ? In Turbo PMAC SRM manual Ixx67 tells "If pure velocity control is desired for the motor, Ixx67 can be set to 0, effectively disabling the position loop " If I am putting this Zero and using Ixx11 and/or Ixx12 , loop is not working properly.
Thanks and regards
