Note

2.

Control From Net shows the input status of word n, bit 5 (Net Control) for CompoBus/D com-

 

 

munications.

 

 

Note

3.

The Reference From Net and Control From Net functions are applicable for Inverter software

 

 

versions S1042 and later. Check the version with the Inverter monitor function U1–14.

Note

4.

Reverse Operation indicates reverse output status. This bit does not turn ON for DC braking

 

 

(DC injection).

 

 

Note

5.

Forward Operation indicates either forward run status or DC braking (DC injection) status.

 

 

This bit turns ON even for DC braking (DC injection) during reverse run.

Content

Communications data = Rotational speed reference x 2a

 

 

 

 

 

 

 

 

 

 

 

a: Speed scale value of Class 2A, Instance 01, Attribute 16 (Initial value: 0)

 

 

 

 

•

The speed scale is assigned to the message function. For instructions on how to change it, refer to 5-2 Mes-

 

 

sage Communications.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

•

The unit for the rotational speed reference is set in o1–03 (frequency reference setting and display units)

 

•

Setting example (providing reference of 1,800 r/min):

 

 

 

 

 

 

 

 

 

When the speed scale value is “0” and the number of motor poles is set in 01–03 (so unit is r/min):

 

 

 

1,800 r/min →

1,800 x20 →

1,800 →

0708 Hex

 

 

 

 

 

 

 

 

 

Note

1.

Under the DeviceNet protocol, the unit for the speed reference is fixed as r/min. The number

 

 

of motor poles (2 to 32) must be set in parameter o1–03 (frequency reference setting and dis-

 

 

play units) when using DeviceNet (open network).

Note

2.

If the setting in not within the proper range, the previous data will be retained and the desig-

 

 

nated rotational speed will not be entered.
