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.

n. †† 1 † Position Control (Pulse train reference)
Controls the position of the servomotor 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.

† Torque Control (Analog voltage reference)
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
pressing.

† Speed Control (Internally set speed selection)
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
. (In this case, an analog ref-
erence is not necessary.)

These are switching modes for using the four control methods described above
in combination. Select the control method switching mode that best suits the
application.
