SYSDRIVE 3G3RV and 3G3PV Settings
In order to perform DeviceNet communications, it is necessary to make settings for the Inverter
according to the application.
Note
The parameters set here are applied to the DeviceNet Communications Card when the power
is turned ON. Turn OFF the power after changing parameters and turn ON again to apply
them.
4-2-1 Frequency Reference Selection
• Select the method for inputting frequency references to the Inverter. Select the method suitable for
the application.
• When frequency references from the DeviceNet communications are to be always used, set to “3."
If this setting is performed, frequency reference 1 can only be set through DeviceNet communica-
tions. However, parameter values set from DeviceNet communications or the Digital Operator are
used for 3G3RV Inverters' frequency references 2 to 16 and inching frequency reference (d1-02 to
d1-17) regardless of the setting of b1-01.
■
Switching of Frequency References from DeviceNet Communications
There is a switching signal, “Net. Ref.,” for frequency references (speed references) from the stan-
dard remote I/O of the DeviceNet Communications Card. The input method for frequency references
can be changed in the following ways using the “Net. Ref.” signal.
Net. Ref. = 1 (ON)
Enables frequency references from DeviceNet communications (remote I/O frequency references
become valid) regardless of the setting in b1-01.
Net. Ref. = 0 (OFF)
Enables the frequency reference setting in b1-01.
