5.6 Operating Using Speed Control with an Internal Set Speed
This function allows speed control operation by externally selecting an input signal from among three servo-
motor speed settings made in advance with parameters in the SERVOPACK. Since controlling a speed with a
parameter inside the SERVOPACK, there is no need for an external speed of pulse generator.
5.6.1 Basic Settings for Speed Control with an Internal Set Speed
Set the following signal and parameter for speed control with an internal set speed.
(1) Signal Setting
The following input signals are used to switch the operating speed.
 Using Input signals /P-CON, /P-CL and /N-CL [Factory setting]
 Using Input Signals /SPD-D, /SPD-A and /SPD-B
(2) Speed Control with an Internal Set Speed Selection
Select the speed control with an internal set speed with Pn000.
