Application Examples

• Tension control

• Pressure control


Pn000.1 Control

Mode

2 Torque

Control

This is a dedicated Torque Control mode.

A torque reference is input from T-REF (CN1-
9).

Speed reference input V-REF (CN1-5) cannot
be used for speed control if Pn002.1 is set to 1.

Parameter Pn407 can be used for maximum
speed control.

Torque Control <-> Speed Control (Analog
Reference)
Switches between torque and speed control

V-REF (CN1-5) inputs a speed reference or
speed limit.

T-REF (CN1-9) inputs a torque reference,
torque feed-forward reference or torque limit
depending on the control mode.

/P-CON (/C-SEL)(CN1-41) is used to switch
between torque and speed control.

Speed Control

Torque Control: When /P-CON (/C-SEL) is OFF

The T-REF reference controls torque.

V-REF can be used to limit servomotor speed
when Pn002.1 is set to 1. V-REF voltage (+)
limit servomotor speed during forward and
reverse rotation.

Parameter Pn407 can be used to limit the
maximum servomotor speed.
