Mitsubishi FR - S500 instruction manual 119, Description Setting, Cr Lf

REMARKS

•For computer link operation, set 65520 (HFFF0) as the value "888" and 65535 (HFFFF) as the value "- - -".

•Refer to page 41 for handling the RS-485 connector.

•Refer to the "parameter data code list" (page 177) for the data codes of the parameters.

<Setting>

To make communication between the personal computer and inverter, the communication specifications must be set to the inverter initially. If initial setting is not made or there is a setting fault, data transfer cannot be made.

Note: After making the initial setting of the parameters, always reset the inverter. After

you have changed the communication-related parameters, communication cannot be made unit the inverter is reset.

Parameter	Description	Setting		Description
				Station number specified for communication from

	station number			Set the inverter station numbers when two or more
				inverters are connected to one personal computer.

				Set the permissible number of retries at occurrence
				of a data receive error.
		0 to 10		If the number of consecutive errors exceeds the
				permissible value, the inverter will come to an
	Number of			alarm stop (OPT).
				If a communication error occurs, the inverter will
n5	communication
				not come to an alarm stop. At this time, the inverter
	retries
				can be coasted to a stop by MRS or RES input.
		- - -
				During a communication error (H0 to H5), the minor
		(65535)
				fault signal (LF) is switched on. Allocate the used
				terminal with any of Pr. 64, Pr. 65 (multi-function
				outputs).
		0		No communication
	Communication			Set the communication check time [s] interval.
				If a no-communication state persists for longer than
n6	check time	0.1 to 999
				the permissible time, the inverter will come to an
	interval			alarm stop (OPT).
		- - -		Communication check suspension
		0 to 150		Set the waiting time between data transmission to
n7	Wait time setting			the inverter and response.
		- - -		Set with communication data.
