Full-closed loop function
Operation step of full-closed loop function:
1. Check mechanism direction
Check the external encoder position direction corresponds to the motor direction. Set Pn314
(Position command direction definition). Confirm by pushing manually (no excitation). When the
external machine is pushed in positive direction, check Un-14 (motor feedback-pulse number in
one rotation) and confirm if the value is incremental.
2. Check if the internal direction the same with external direction
Push the external machine in positive direction manually (no excitation), check Un-50 (external
encoder pulse number) and confirm if the value is incremental. If not, please correct Pn349
(full-closed loop direction) setting to 0 or 1.
3. Confirm Pn348 (external encoder resolution)
