9.5 Control Mode Selection
The control modes supported by the SGDH SERVOPACK are described below.

(Factory
setting) Speed Control (Analog voltage speed reference)
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 feedback division output from the
SERVOPACK to form a position loop in the host controller.
9.7
n.††1† Position Control (Pulse train position reference)
Controls the position of the machine by means of a pulse train position refer-
ence.
Controls the position with the number of input pulses, and controls the speed
with the input pulse frequency. Use when positioning is required.
9.8
n.††2† Force Control (Analog voltage speed reference)
Controls the linear servomotor’s output force by means of an analog voltage
force reference. Use to output the required amount of force for operations such
as pressing.
9.9
n.††3† Speed Control (Contact input speed control)
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 oper-
ating speeds can be set in the SERVOPACK. (In this case, an analog reference is
not necessary.)
