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.
5.4.4.2 Analog value corresponding to rated speed
V-REF function
distribution
Analog quantity
corresponding to rated
speed
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.
