SYSDRIVE Inverter Settings
4-3 SYSDRIVE 3G3FV 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.
4-3-1 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 frequency references 2 to 8 and the inching frequency reference (d1-02 to d1-09) regard-
less 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. This function cannot be used with the
3G3FV.
When it is necessary to switch frequency references from DeviceNet communications, change the
setting in parameter b1-01 with an explicit message (Class 64 hex, Instance 01 hex, Attribute 03
hex).
