9.6.3.2 Modbus Communication
A Modbus RTU protocol is available on all the fan models.
The line must be connected to MODBUS-A, MODBUS-B and GND pins.
There are two possible Modbus connections:
1) During the fan functioning through any RS-485 serial connection
2) With the driver powered off through an UART serial connection
To connect OFFLINE the driver to a PC when the fan is powered off, a USB to UART converter can be used: K431A6 for 1-phase
drivers and K431F7 for 3-phase drivers.
A MOLEX connector "1" is used to connect the cable to the driver.
To connect the driver to a PC during the fan functioning, a USB to 485 converter can be used: K431F8.
