Mitsubishi FR - S500 Operation and speed command write, N9 Pr Speed Command write

2.14.2 Operation and speed command write

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 write			Setting is enabled when Pr. 30 = "1"
n9 (339)	Speed command	0	0, 1
	write

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 sequence program are as listed below.

(Refer to page 88 for Pr. 60 to Pr. 63 (input terminal function selection).)
