2.2 Control Modes

2-9

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 OW††00).
