■Communication function parameters (Common serial options)

E6580757

■Communication function parameters (Common serial options)

The data transfer speed, parity type, inverter number, and communication error trip time can be set/edited by operation panel operation or communication function.

Title		Function	Adjustment range	Default setting

			0: 1200bps
			1: 2400bps
	Data transfer speed		2: 4800bps	3
			3: 9600bps
			4:19200bps
			0: NON (No parity)
	Parity	(Common serial)	1: EVEN (Even parity)	1
			2: ODD (Odd parity)
	Inverter number		0 ∼ 63	0

	Communication error trip time		0: Disabled *	0
	Communication error trip time		1 ∼ 100 (s)	0
			1 ∼ 100 (s)

*Disabled ........... Indicates that the inverter will not be tripped even if a communication error occurs.

Trip ...................The inverter trips when a communication time-over occurs. In this case a trip information

" " flashes on and off on the operation panel.

■Setting the communication functions

6

Setting commands and frequencies by communications has priority over sending commands from the opera- tion panel or the terminal board. Command/frequency setting by communications can therefore be enabled,

irrespective of the setting in the command mode ( ) or the frequency setting mode ( ). However, when the input terminal function selection parameter is set to 48: SC/LC (Serial/Local selection),

the inverter can be operated with the settings of the command mode ( ) or the frequency setting mode

( ) by external input.
