2.15.1 Communication settings (n1 to n7 , n11 )

Communication-related parameters

Parameter	Name	Factory	Setting	Remarks	Reflection
		Setting	Range		Timing
n1(331)	Communication station number	0	0 to 31		After reset
n2(332)	Communication speed	192	48,96,192		After reset
n3(333)	Stop bit length	1	0,1,10,11		After reset
n4(334)	Parity check presence/ absence	2	0,1,2		After reset
n5(335)	Number of communication	1	0 to 10,	Setting is enabled Immediately
	retries		- - -
n6(336)	Communication check time	---	0, 0.1 to	when Pr. 30 = "1"	Immediately
	interval (*)		999s, - - -
			0 to
n7(337)	Waiting time setting	---	150ms,		After reset
			- - -
n11(341)	CR/LF selection	1	0,1,2		After reset

•The parameter numbers within parentheses are those for use of the parameter unit (FR-PU04).

•Refer to page 180 for the instruction codes.

POINTS

*When making RS-485 communication, set any value other than 0 in the communication parameter n6 "communication check time interval". RS-485 communication is disabled if the setting is "0s".

REMARKS

•For computer link operation, set 65535 (HFFFF) as the value "- - -" and 65520 (HFFF0) as the Pr. 19 value "888".

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

•For parameter instruction codes, refer to the appended parameter instruction code list (page 180).
