Inverter Interface
SECTION 5

Controlling Inverter I/O
Inputs
By default, all inputs can be monitored in IR (Ch204). However, they may
have functionality attached to it. The function can be changed using
n50..n56.
Note
Setting the corresponding bit in Ch207 an input can be turned on.
The analog input can be monitored in DM2034.
Outputs
By default, outputs can not be controlled in IR. To control the outputs (Bits
0..2 in Ch208) the corresponding output setting (n57..59) must be set to "18".
This means that 'communication’ (in this case the 3G3MV-P10CDT) controls
the corresponding output.

Transfer command
Parameters which are accessible through a corresponding Modbus register
inside the 3G3MV Inverter, can be accessed by using the Transfer com-
mand.
The Transfer command is controlled by
•
Two command bits: one for reading and one for writing
•
Three status flags: busy-, completion- and error-flag
•
Two DM area’s: one for specifying the command, one for specifying the
response location.
Note
Changes to parameters may not take effect immediately. Refer to the 3G3MV
Manual for details.
All parameters accessed with the Transfer command use the register num-
bers and formats of the Modbus-interface as defined by 3G3MV.
Note
The following parameters have different register numbers when accessed
through the Transfer functionality compared to accessing through Modbus:
Parameter
Transfer register number
n128 1D3H
n129 1D4H
U-03 3BH
Note
The data-format of following parameters are different when accessed through
the Transfer functionality compared to accessing through Modbus:
