5.3.1 Basic Settings for Speed Control

This section describes the basic settings for speed control.
(1) Signal Setting
Input the speed reference to the SERVOPACK using the analog voltage reference to control the servomotor
speed in proportion to the input voltage.
Type Signal Name
V-REF
Input
SG
Maximum input voltage: ±12 VDC
Input Circuit Example
Example:
Motor rated speed with Pn300 = 006.00: 6.00 V [Factory setting]
Note: The setting value is 600, but it will be displayed on the operator as 006.00.
