Group bA Communication parameters
bA-00
Communication type selection
Default
0
Setting Range
0: Modbus protocol
The EM15 now supports Modbus, later will add the communication protocol such as PROFIBUS-DP and
CANopen protocol. For details, see the description of “EM15 communication protocol”.
bA-01
Baud ratio setting
Default
5
Setting Range
0:300BPS
1:600BPS
2:1200BPS
3:2400BPS
4:4800BPS
5:9600BPS
6:19200BPS
7:38400BPS
This parameter is used to set the data transfer rate from host computer and the frequency inverter. Please note that
baud ratio of the host computer and the inverter should be consistent. Otherwise, the communication is impossible.
