J Selecting Torque Control
Use the following parameter to select level 3 or level 4 torque control.
Cn-2B
Control Mode Selection Factory
Setting: 0
For Speed/Torque Control
and position Control
This is dedicated torque control.
A motor torque reference value is externally input into the SERVOPACK to control
torque.
Examples of Use: Tension control
Pressure control

Torque Control
This is a dedicated torque control mode.
A torque reference is input from T-REF
(1CN-9).
/P-CON is not used.
Speed reference input V-REF (1CN-5) can

Torque Control $ Speed Control (Analog
Reference)
Torque control and speed control can be
switched.
A speed reference or speed limit value is
input from V-REF (1CN-5).
T-REF (1CN-9) inputs a torque reference,
torque feed-forward reference or torque limit
value depending on the control mode used.
/P-CON (1CN-41) is used to switch between
torque control and speed control.
