Omron 3G3MV-PDRT2 User Manual page 107

Remote I/O Functions
Note 1. In this manual, the parameter location for the 3G3MV is written ahead of the parameter lo-
cation for the 3G3RV/3G3PV/3G3FV, so "n003/b1-02" indicates a parameter location of
n003 for the 3G3MV and parameter location of b1-02 for the 3G3RV/3G3PV/3G3FV.
Note 2. Net Control is used to change the run command as follows (cannot be changed while the
Inverter is running):
0: The run command input method specified by the run command source selection
(n003/b1-02) is used.
1: Operate by DeviceNet regardless of the setting in n003/b1-02 (according to the run com-
mand in word n, bits 0 and 1). (This setting is invalid in the 3G3FV Inverters.)
Note 3. Net Reference is used to specify the frequency reference as follows (cannot be changed
while the Inverter is running):
0: The frequency reference input method specified by the frequency reference source selec-
tion (n004/b1-01) is used.
1: Operate by DeviceNet regardless of the setting in n004/b1-01. (Operates with rotational
speed reference in word n+1.) (This setting is invalid in the 3G3FV Inverters.)

Signal name Rotational speed reference data
Content
Communications data = Rotational speed reference x 2
* The speed scale is assigned with the message function. For instructions on how to
change it, refer to Chapter 6 Message Communications.
* The unit for the rotational speed reference is set in n035/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 n035/o1-03
(so unit is r/min):
1,800 r/min → 1,800 x2
Note 1. Under the DeviceNet protocol, the unit for the speed reference is fixed as r/min. The number
of motor poles (2 to 39) must be set in parameter n035/o1-03 (frequency reference setting
and display 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 des-
ignated rotational speed will not be entered.
