gefran AFE200 Series

AFE200 • Instruction Manual 111
14 - COMMUNICATION
The AFE200 drive is provided with a standard port (9 pole sub-D connector: XS) for connecting the
RS485 serial line used for drive-PC point-to-point communication (via the GF-eXpress conguration
software) or for the multidrop connection.
The RS485 serial line format is: 8 data bits, no parity and one stop bit.

14.1.4 3804 Serial protocol ENUM Modbus 0 1 ERW
Setting of the serial communication protocol:
0 Modbus
1 Jbus
Setting to 0 selects the Modbus RTU (Remote Terminal Unit) serial communication
protocol.
Setting to 1 selects the Jbus serial communication protocol. The Jbus protocol is func-
tionally identical to the Modbus, except for the different numbering of addresses: in the
Modbus these start from zero (0000 = 1st address) while in the JBUS they start from
one (0001 = 1st address) and maintain this difference throughout numbering.

14.1.5 3806 Serial delay ms UINT16 0 0 1000 ERW
Setting of the minimum delay between the drive receiving the last byte and starting
its response. This delay avoids conicts on the serial line when the RS485 interface
that is used has not been pre-set for automatic Tx/Rx switching. The parameter only
