Overtravel input

0 – 1

In the case of linear driving, in particular, to prevent mechanical damage due to

inhibit

overtraveling of work, you should provide limit switches on both ends of the axis, as

shown below, whereby driving in a direction of switch action is required to be

inhibited.

Disable

Both CCWL and CWL inputs are ignored and they normally operate as no

overtravel inhibit being set.

<Cautions>

1.When you set 0 to Pr04 and do not connect both CCWL and CWL inputs to COM- (off), abnormal condition in which limits are exceeded in both CCW and CW directions is detected, and the driver will then trip due to “abnormal overtravel input inhibit“.

2.You can set whether or not to activate the dynamic brake when slowdown occurs because CCW or CW overtravel input inhibit has been enabled. For details, refer to descriptions on Pr66 (DB deactivation at overtravel input inhibit).

06	ZEROSPD input	0 – 1 This sets switching of enable and disable of speed zero clamp input (ZEROSPD,
	selection	CNX5 26-pin).
			Setting value			Function of ZEROSPD Input (26-pin)
			[0]	ZEROSPD input being ignored, it is determined that it is not speed
				zero clamp state at all times.
			1	ZEROSPD input has been enabled. If connection with COM- is
				opened, speed command will be regarded as zero.
07	Speed monitor	0 – 9 The parameter			selects/sets	a relationship between voltage output to the speed
	(SP) selection	monitor signal output (SP: CN X5 43-pin) and the actual motor speed or command
		speed.
			Setting value		SP Signals	Relationship between Output Voltage Level and Speed
