Speed Control
Section 10-5
W-series Acceleration/Deceleration Constants for Speed Control
The Soft Start Acceleration Time and Soft Start Deceleration Time are set
respectively as the acceleration time and deceleration time between speed 0
(speed command value for speed control: 0%) and the momentary maximum
rotation speed of the Servomotor (speed command value for speed control:
100%).
The acceleration time and deceleration time for the actual target speed are as
follows:
Note The momentary maximum rotation speed depends on the Servomotor used.
Refer to the momentary maximum rotation speed for the Servomotor used.
The following values apply to W-series Servomotors.
3,000-r/min Servomotor (cylinder type or flat type): 5,000 r/min
1,000-r/min Servomotor: 2,000 r/min
1,500-r/min Servomotor (450 W to 7.5 kW): 3,000 r/min
1,500-r/min Servomotor (11 to 15 kW): 2,000 r/min
Option Command Value during Speed Control
When speed control is used, the torque limit and torque feed forward func-
tions can be applied during speed control by setting Servo Parameter
