Modbus control

You must set the slave address to something valid (non-zero) and use some form of RTU mode instead of ASCII for most software stacks to communicate with the VFD:

Parameter	Default Value	Needed Value	Description
PD000	1: parameter editing locked	0: parameter editing unlocked	parameter editing lock
PD163	0: invalid	1: address of 1	slave address
PD164	1: 9,600 baud	1: 9,600 baud	baud rate
PD165	0: ASCII,8N1	3: RTU,8N1	ASCII vs RTU,data bits,parity,stop bits
