1. Set the motion fixed parameters according to the user’s machine.
Table 2.3 shows the related parameters when the torque reference output mode is used.
* 1. Valid only with an SVB-01 Module.
* 2. Valid only with an SVA-02A Module.
2. Set the motion parameters to be used in the torque reference output mode.
3. Select the Torque Reference Output Mode (TCON) (bit 1 of OW00).
4. To start operation, set the RUN Servo ON (RUN) to ON (bit 0 of OW01).
The torque reference and the speed limit reference will be output for the axis according
to the specified motion parameters.
Even while the torque reference output mode is being selected, the motion parameter
settings can be changed.
5. To stop operation, set the RUN command (RUN) and the torque reference output mode
(TCON) to OFF.
