09-00	Communication Address
Control	VF	VFPG SVC FOCPG TQCPG FOCPM	Factory Setting: 1
mode
	Settings	1 to 254

If the AC motor drive is controlled by RS-485 serial communication, the communication address for this drive must be set via this parameter. And the communication address for each AC motor drive must be different and unique.

09-01	Transmission Speed					Unit: 0.1
Control	VF	VFPG	SVC		FOCPG TQCPG FOCPM	Factory Setting: 9.6
mode
	Settings	4.8 to 115.2kbps
This parameter is used to set the transmission speed between the RS485 master (PLC, PC,
etc.) and AC motor drive.
09-02	Transmission Fault Treatment
Control	VF	VFPG	SVC		FOCPG TQCPG FOCPM	Factory Setting: 3
mode
	Settings	0		Warn and keep operating
		1		Warn and RAMP to stop
		2		Reserved
		3		No action and no display

This parameter is set to how to react if transmission errors occur.

09-03	Time-out Detection		Unit: 0.1
Control	VF	VFPG SVC FOCPG TQCPG FOCPM	Factory Setting: 0.0
mode
	Settings	0.0 ~ 100.0 sec (0.0: disable)

It is used to set the communication time-out time.
