Chapter 4 Parameters

Group 9: Communication Parameters

There is a built-in RS-485 serial interface, marked RJ-11 near to the control terminals. The pins are defined below:

1: EV

2: GND 3: SG-

4: SG+

5: Reserved 6 1 6: Reserved

Each VFD-VE AC drive has a pre-assigned communication address specified by Pr.09-00. The RS485 master then controls each AC motor drive according to its communication address.

09-00	Communication Address
Control	VF	VFPG SVC FOCPG TQRPG	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	COM1 Transmission Speed
Control	VF	VFPG	SVC		FOCPG TQRPG	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	COM1 Transmission Fault Treatment
Control	VF	VFPG	SVC		FOCPG TQRPG	Factory Setting: 3
mode
	Settings	0			Warn and keep operating
		1		Warn and RAMP to stop
		2		Warn and COAST to stop
		3		No warning and keep operating

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