MODE UP DOWN SET

(2)When changing the parameter

Turn off then on the servo amplifier to be effective the new parameter.

16.5.4Station number setting

Set each station number so that no station number overlaps.

The station number can be set without regard to the cable connection order. There is no problem even if station numbers are not consecutive.

Examples of station number setting

(1)Direct specification

When setting the device, specify the station number of the servo amplifier of which data is to be changed.

Specification

range

0 to 31

(2)Indirect specification

When setting the device, indirectly specify the station number of the inverter of which data is to be changed using the 16-bit GOT internal data register (GD10 to GD25).

When specifying the station No. from 100 to 115 on GT Designer3,the value of GD10 to GD25 compatible to the station No.specification will be the station No.of the servo amplifier.
