Detailed instruction of parameters
After the VFD stops, when the operation frequency is
less than P01.09, set P13.15 to non-zero value and
begin stopping short-circuit braking and then DC
braking.
Setting range of P13.13: 0.0–150.0% (VFDs)
Setting range of P13.14: 0.00–50.00s
Setting range: 1–247
When the master is writing the frame, the
communication address of the slave is set to 0; the
broadcast address is the communication address. All
slaves on the MODBUS fieldbus can receive the frame,
but the salve doesn't answer.
The communication address of the VFD is unique in the
communication net. This is the fundamental for the point
to point communication between the upper monitor and
the VFD.
Note: The address of the slave cannot set to 0.
Set the digital transmission speed between the upper
monitor and the VFD.
0: 1200BPS
1: 2400BPS
2: 4800BPS
3: 9600BPS
4: 19200BPS
5: 38400BPS
6: 57600BPS
Note: The baud rate between the upper monitor and the
VFD must be the same. Otherwise, the communication
is not applied. The bigger the baud rate, the quicker the
communication speed.
The data format between the upper monitor and the VFD
must be the same. Otherwise, the communication is not
