Speed Control
Controls servomotor speed by means o
f 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.
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 f
requency. Use when posi-
tioning is required.
5.4 Position
Control
n.2 Force Control
Controls the servomotor’s output force by means of
an analog
voltage force reference. Use to output the required amount of
force 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.
