Chapter 6 Communication Protocol
SVF-MN series VFD communicate with PC, PLC etc upper
machines, and they need the support of J16PIN crystal plug seat.
Between the upper user machine and frequency inverter
communicate through the international standard ModBus
communication, and the upper user machine as host machine, and
the frequency inverter as slave machine. The communication
content could be finished as follows: send operating command to
frequency inverter, setting operating frequency, changing function
code parameters, reading frequency inverter operation situation,
monitoring parameters, fault information, function code etc.
6.1 Communication Allocation
Set baud rate and parity bit through P89, P92.
