4 Motion Control
4.2.4 Phase Control Mode
4-16
„ Details
Use the following procedure to perform phase control operation.
1. Set the motion fixed parameters according to the user’s machine.
* 1. Valid only with an SVB-01 Module.
* 2. Valid only with an SVA-02A Module.
2. Set the motion parameters. Use the user program to control the reference speed so that no
shock occurs.
The following three methods can be used to set the setting parameters.
• Using the MPE720 Setting Parameter Window
• Using a ladder logic program
• Using a motion program
Table 4.5 shows the related parameters when the phase control mode is used.

1. Set the motion fixed parameters.
2. Set the motion setting parameters.
3. Select the phase control mode (PHCON).
4. Set the RUN command (RUN) to ON.
