The Flexible format lets you operate the Inverter using the Modbus registers
directly. Parameters P160 to P169 and P170 to P179 can be used to map
Modbus registers into the cyclically exchanged IO data. User parameters
P160 to P169 configure the output data words where parameters P170 to
P179 configure the input data words.
Please refer to the APPENDIX F Flexible Format on page 79 for details on the
flexible mode.
Configure the Option Board and Network as explained in sections 3-1 Installa-
tion of EDS files and 3-2 Configuring the Option Board.
Set parameters P160 to 1F01h to map coil data 0 as the first output word.

quency reference (F001) as the 2
Set parameter P170 to 0005h to map Inverter status C as the first input word.
Set parameter P171 to 1E01h to map coil data 1 (coil no 0010h to 001Fh) into
the second input word.
Set parameters P172 and P173 to 1001h and 1002h to map the Modbus fre-
quency monitor (d001) as the third and fourth input word.
Restart the Inverter or reset the Option Board for the new settings to take
