Explanation
Ball screw
1
Confirm the mechanical specification
Ball screw pitch: 5mm
Reduction ratio: 40/1
2
Confirm the encoder pulse number
2500P/R
3
Decide the command unit
1 command unit: 0.001mm
4
Calculate the motion value of load
shaft rotate 1 circle
5mm/0.001mm = 5000

 Debug
1. Initial debug
(a) Connect the cables correctly. Connect U, V, W, PE one-to-one, don’t cross them.
(b) open-loop test-running: power on, set F1-01=1, check if the motor can work normally. If yes, enter
F1-00. If not, check the cables.
(c) Jog test-running: enter F1-00. Press ENTER to enable the motor. Press INC for forward jog, press
DEC for reverse jog. Press STATUS/ESC to quit the jog running.
4 states when jogging:

Reverse run
(d) Current check offset auto-adjustment
Enter F1-02, it shows rEF.
Press ENTER, it shows rEF and flickers.
After 5s the auto-adjustment finished, it shows donE.
Press STATUS/ESC to exit.
2. Debug the motor with machine
(a) Check the motor rotation direction, if it is reverse from the actual needs, set F1-05 to 0 (servo force
OFF). Then set P0-05 to 1, re-power on the servo.
(b) Check the servo stability and response, adjust the servo gain.
3. Debug with PLC program.
