					E6580772③
Parameter name	Title	Setting value			Details
Com. Error	f850	0 to 4	Sets the inverter operation at time of communication error.
selection			The	action of inverter	will be different depending on the
			status (during operation or halt) of the inverter. (Note 2)
			0:	During halt	Inverter stops after free run.
				During operation	Inverter trips.
			1:	During halt	Inverter stops after free run.
				During operation	Inverter stops after free run.
			2:	Invalid	(Setting is enabled with F10M
					option connected.)
			3:	During halt	Inverter decelerates to stop.
				During operation	Inverter decelerates to stop.
			4:	During halt	Inverter continues to run.
				During operation	Inverter continues to run.
Com. Error	f851	0 to 1000	Sets	the time until the	communication error is detected.
detecting time			Setting is done by a unit of ms. (Note 3)
Reset function	f899	0, 1	Resets the inverter station.
			0:	No action
			1: To reset the inverter station. After resetting, setting
				data returns to 0.

(Note 1) For setting the parameters, never duplicate the station address on the same communication line. PLC rink relay register is automatically allocated according to the setting of the station address. As for the setting of station addresses, consider the allocation of rink relay register that is determined by the other station addresses and the number of words that have been set in the parameters f831 to f836, and f841 to f846.

The maximum setting value for station address is 255, however when 255 is set, only one word of scan data can be set. To set the scan data in its maximum value of 12 words, setting value of the station address should be: 255-(12-1)= 244.

(Note 2) Setting of “free-run stop” is valid when the “operation command mode selection” [cmod] is selected to the optional add-on cassette.

Setting of “deceleration stop” is valid when the “operation command mode selection” [cmod] is selected to the optional add-on cassette or when the “speed setting mode selection” [fmod] is selected to the optional add-on cassette. At the same time the deceleration stop returns the command of run/stop and the speed reference value to 0. Except when the above command setting is selected, inverter cannot be stopped.

Furthermore when the “operation command mode selection” [cmod] is set to other than the optional add-on cassette and when the “speed setting mode selection” [fmod] is selected to the optional add-on cassette, in some cases inverter can not stop running because of the setting of the parameters (zero- speed operation setting). Torque control is valid when the “operation command mode selection” [cmod] is set to the optional add-on cassette, but the inverter operation becomes “free-run stop” at that time.
