Application Examples
Tension control
Pressure control
Pn000.1
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.

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.

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 rota-
tion.
•parameter Pn407 can be used to limit the maximum
servomotor speed.
