11.3 Other functions
11.3.1 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 the each axis separately at ±software limit (±software
limit) parameter.

-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.
11.3.2 Stop current
When it stops, set the stop current supplied at the motor phase to decrease motor heat and
current consumption.

Factory default is 50% of max. run current. It is available to set at the parameter.
Parameter Setting range Unit Unit value factory default
Stop Current 20 to 100 % 1 50
11.3.3 Stop Current Fix
Set the stop current control method; Enable, Disable (factory default).

Enable: Fixed stop current
: It maintains stop current as the set value at the parameter.

Disable: Setting stop current
: It adjusts by stop current load and it is able to reduce over heat of motor.
