9.2.5.2 Limit Home Search
Connect the external limit sensor to ‘±Limit’ and receive the signal output from the sensor
to designate as home.
If the parameter ‘Software Limit’ is set to ‘Enable’, the home search mode is available with
Software ±Limit.
1st
Click button and select ‘Limit Home Search’.
2nd
Click button to execute the home search operation.
3rd
When the operation is executed, the motor operates in the direction set in the
parameter ‘Home Search Direction’.
4th
Operation starts according to the start speed set in the parameter ‘Home Search
Start Speed’, and acceleration starts according to the acceleration time set in the
parameter ‘Home Search Acceleration Time’.
5th
The constant speed operation is performed until a signal is input to the limit
sensor ‘±Limit’ when the maximum speed set in the parameter ‘Home Search
Max Speed’ is reached.
6th
If a signal is input to the limit sensor (±Limit) or reaches to Software ±Limit, the
motor decelerates and stops according to the deceleration time set in the
parameter ‘Home Search Deceleration Time’.
7th
After stop, it moves to the opposite direction as far as the distance past the limit
sensor at the sart speed set in the parameter ‘Home Search Start Speed’ to find
the limit sensor and stops.
8th
When the home found, the operation completion signal (In-Position) is output
and the In-Position indicator lights to indicate the status.

If a value other than 0 is set in the parameter ‘Home Search Offset’, it moves to the set
position value after finding the home and outputs the operation completion signal (In-
Position) and lights up in the In-Position indicator to display the status.

If a value other than 0 is set in the parameter ‘Home Search Position Set’, the position
specified after finding the origin is set to the set value other than 0.

If the deceleration time is set long during deceleration and stop, it may collide with the
structure, so the deceleration time should be set short or the limit sensor should be
installed from the structure with sufficient margin.
