5-35
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.

9 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.

Open Torque Control
0 V 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.
