15.3.2 Torque control mode
(1) Power on
1) Switch off the servo-on (SON).
2) When power is switched on, the display shows "U (torque command voltage)", and in two second later,
shows data.
(2) Test operation
Using jog operation in the test operation mode, make sure that the servo motor operates. (Refer to section
6.8.2.)
(3) Parameter setting
Set the parameters according to the structure and specifications of the machine. Refer to chapter 5 for the
parameter definitions and to section 6.5 for the setting method.

Turn the power off after setting parameters No.0 and 1. Then switch power on again to make the set
parameter values valid.
(4) Servo-on
Switch the servo-on in the following procedure.
1) Switch on power supply.
2) Switch on the servo-on (SON).
When placed in the servo-on status, the servo amplifier is ready to operate and the servo motor is
locked.
(5) Start
Using speed selection 1 (SP1) and speed selection 2 (SP2), choose the servo motor speed. Turn on
forward rotation select (DI4) to run the motor in the forward rotation (CCW) direction or reverse rotation
select (DI3) to run it in the reverse rotation (CW) direction, generating torque. At first, set a low speed and
check the rotation direction, etc. If it does not run in the intended direction, check the input signal.
On the status display, check the speed, load factor, etc. of the servo motor.
When machine operation check is over, check automatic operation with the host controller or the like.
