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 to be used in the speed reference output mode.
The following three methods can be used to set the motion setting parameters.
• Using the MPE720 Setting Parameter Window
• Using a ladder logic program
• Using a motion program
* Valid only with an SVA-02A Module.
In the examples, SERVOPACK is used as axis 1 of Module No. 1. When the Module
number and the axis number are different, see 4.1.2 Modules and Motion Parameter
Registers, and change the register numbers.
3. Select the Speed Reference Output Mode (NCON) (bit 0 of OW00).
