INITIALIZING SERVO PARAMETERS
3.4.1
Servo Amplifier Unit
(1) Before servo parameter initialization
Before starting servo parameter initialization ,confirm
the following:
1) NC model (Example: Series 16-C)
2) Servo motor model (Example: β6/2000)
3) Pulse coder built in a motor
(Example: β pulse coder)
4) Whether a separate position detector is used or
not
(Example: Not used)
5) Distance the machine tool moves per revolution
of the motor
(Example: 10mm per one revolution)
6) Machine detection unit (Example: 0.001 mm)
7) NC command unit (Example: 0.001 mm)
(2) Servo parameter initialization procedure
1) Switch on the NC in an emergency stop state.
Enable parameter writing (PWE=1)
2) Initialize servo parameters on the servo setting
screen.
To display the servo setting screen, follow the
procedure below, using the key on the NC.
• Series 16,18,20,21
SYSTEM → [SYSTEM] → [ ] → [ SV-PRM]
If no servo screen appears, set the following parameter as
shown, and switch the NC off and on again.
#7 #6 #5 #4 #3 #2 #1 #0
3111 SVS
SVS (#0) = 1 (to display the servo screen)
