Note

1. The Net Reference and Reference From Net functions are applicable for Inverter software

 

 

versions S1042 and later. Cannot be changed during running. Check the version with the In-

 

 

verter monitor function U1–14. If the software version is S1040, set b1–01 to “3.”

 

 

Note

2. Under the DeviceNet protocol, the unit for the speed reference is always 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

3. Cannot be changed during running.

 

 

 

 

 

 

DCommunications Data Setting Examples

Example 1: Finding the communications data for outputting a frequency of 60 Hz with the following conditions set.

Number of poles (o1–03): 4

Speed scale (attribute 16): 0

•Converting frequency to rotational speed:

Frequency x 120 / number of poles = 60 x 120/4 = 1,800 r/min

•Converting rotational speed to minimum unit: Rotational speed / unit = 1,800 / (1 r/min x 1/20) = 1,800

•Converting communications data to hexadecimal: 1,800 (dec) = 708 (hex)

Example 2: Finding the communications data for outputting a frequency of 60 Hz with the following condition set.

Frequency setting (o1–03): 0 (Cannot be set with DeviceNet protocol.)

•Converting frequency to minimum setting unit: Frequency / minimum unit = 60 / 0.01 = 6,000

•Converting communications data to hexadecimal: 6,000 (dec) = 1,770 (hex)
