[Factory setting]
Speed Control
Controls servomotor speed by means of an analog voltage speed
reference. Use in the following instances.
• To control speed
• For position control using the encoder pulse output from the
multi-winding drive unit to form a position loop in the host
controller.
5.3 Speed
Control
n.1 Position Control
Controls the position of the machine by means of a pulse train
position reference.
Controls the position with the number of input pulses, and con-
trols the speed with the input pulse frequency. Use when posi-
tioning is required.
5.4 Position
Control
n.2 Torque Control
Controls the servomotor’s output torque by means of an analog
voltage torque reference. Use to output the required amount of
torque for operations such as stopping on contact.

Internal Set Speed Con-
trol
Uses three operating speeds set in advance in the multi-winding
drive unit as references to preform speed control.
When selecting this control, an analog reference is not necessary.
