4-10
* 1. Valid only with an SVB-01 Module.
* 2. Valid only with an SVA-02A Module.
2. Set the motion parameters.
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
* Valid only with an SVA-02A Module.
