5. Description of Function Codes
69
b9-08
Accumulative running time
Default
--
Setting Range
0~65535 h
It is used to display the accumulative running time of the frequency inverter. After the accumulative running time
reaches the value set in b2-21, the terminal with the digital output function 12 becomes ON.
b9-09
Accumulative power-on time
Default
--
Setting Range
0~65535 h
It is used to display the accumulative power-on time of the frequency inverter since the delivery. If the time reaches
the set power-on time (b2-20), the terminal with the digital output function 24 becomes ON.
b9-11
Auxiliary LED display parameters
Default
00004
Setting Range
Corresponding U0 group parameters
It is used to setting auxiliary LED display parameters.
For Example:
If b9-11 setting to 00001, the auxiliary LED display setting frequency (U0-01)
If b9-11 setting to 00004, the auxiliary LED display output frequency (U0-04)
5.10 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 optional communication protocol such as PROFIBUS-DP and
CANopen. 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 baud rate from host computer to frequency inverter. Please note that
baud rate of the host computer and the inverter should be consistent. Otherwise, the communication is impossible.
The higher the baud rate is, the faster the communication is.
bA-02
Modbus Data format
Default
0
Setting
Range
0
No check, data format <8,N,2>
1
Even parity check, data format<8,E,1>
2
Odd Parity check, data format<8,O,1>
3
No check, data format <8,N,1>
The host computer and inverter setup data format must be consistent, otherwise, communication is impossible.
