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 out-
put from the SERVOPACK to form a position
loop in the host controller.

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. 5.5 Torque

Internal Set Speed Con-
trol
Uses the three input signals /P-CON (/SPD-D), /P-
CL (/SPD-A), and /N-CL (/SPD-B) to control the
speed as set in advance in the
SERVOPACK . Three
operating speeds can be set in the SERVOPACK .
When selecting this control, an analog reference is
not necessary.

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 controls the speed with the input pulse
frequency. Use when positioning is required.
