5.4.4.1 External analog speed mode 
Speed control: external analog value   
Function: speed command is given by external analog quantity. The analog voltage command input 
from the V-REF terminal is given as the speed control signal to control the speed. 
Note: 
(1) Direction switching: positive and negative voltage or SPD-D (P5-27) can control direction. 
(2) Refer to section 3.2.4 analog input circuit for hardware wiring.

Function description: set the speed command voltage (V-REF) required to run the servo motor at rated 
speed. 
For example, P3-01 = 5000, indicating that when the analog input voltage is 5.00V, the motor operates 
at the rated speed; 
P3-01 = 8000, indicating that when the analog input voltage is 8.00V, the motor operates at the rated 
speed.
