Mitsubishi Electronics FR-S500 instruction manual Operation and speed command source n8 , n9

Communication parameters

2.15.2 Operation and speed command source (n8 , n9 )

Used to make valid the operation and speed commands from the computer or external terminals.

Parameter	Name	Factory	Setting	Remarks
		Setting	Range
n8 (338)	Operation	0	0, 1
	command source			Setting is enabled when Pr. 30 = "1"
n9 (339)	Speed	0	0, 1
	command source

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

<Setting>

In the computer operation mode, commands from the external terminals and computer are as listed below.

(Refer to page 98 for Pr. 60 to Pr. 63 (input terminal function selection).)
