12.2.1 Limit Operation
Hardware and software limits can be used to stop drive.

Hardware limit
Install a limit sensor to the machine to monitor system operation directly.
Connect Nlmt+/- (Pin19, 20) at I/O connector (CN3).

Set Instant (instant stop) / Slow (deceleration stop) at Limit Stop Mode (limit Stop
mode) of Operation Mode.

Software limit
Unlike the input of hardware limit signal by external sensor, this limit function is set
using internal position data.
To operate software limit, set software limit (software limit) as Enable.
High and low limit values can be set each axis separately at ±software limit (±software
limit) parameter.
Operation Mode Setting value Parameter Setting value
Software Limit Enable
+Software Limit 100,000
-Software Limit -50,000
When the setting value is as above, the position value operates among -50,000 to
100,000 range. When it is out of the range, the drive decelerates and stops.
Hardware limit operates independently regardless of the software limit settings, and
only hardware limit except limit home search is operated during home search.
