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
SERVOPACK to form a position loop in the host controller.

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.

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 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
SER-
VOPACK
.
When selecting this control, an analog reference is not necessary.
