BASIC CONTROL Mode
5-3 Torque Control
The CJ1W- and CS1W-NCx71 Position Control Units for MECHATROLINK-II issue the torque
control commands. The Servo Drive uses the commands and rotates the motor in the
commanded torque output. The present value to be fed back from the Drive to the Controller
is the values obtained by dividing the command by the Electronic Gear Ratio (determined by
the settings in Pn009 or Pn010).
Precautions for Correct Use
 While the motor speed is restricted by the Speed Limit Command, the Torque Command to the
motor differs from the Torque Command issued by the Host Controller. The Torque Command to
the motor is the resulting value that controls the motor speed within the Speed Limit.
Parameters Requiring Settings
Speed Limit Selection (Pn317)
Restricts the speed as the protection during torque control.
Controls that the speed does not exceed the Speed Limit during torque control.
