Home Search Configuration by Limit Signal
This is simple home search and the way the other side of the limit signal will serve as the home signal�
There are two conditions as the following:
●
In case of high speed detection operation, the limit signal can be decelerated enough to stop within the
distance to mechanical limit from the position that the signal is activated�
●
The start position for the home search is within the active block of the limit signal�
E.g.) The limit signal of the - direction ins served as the home signal is as follows:
● Connect LMT- input to the input terminals of STOP0 and STOP1.
● Since the high speed home search of step 1 is carried out, set the Limit Stop Mode to the deceleration
stop in Mode tab.
● Configure LMT-, STOP0, STOP1 signal levels identically.
● Enable the Using Limit Signal in Home Search Mode tab.
● Start the step 4 (high speed offset movement), and end it after escaping the limit.

Step 1 is moved to the limit in - direction in high speed. If LMT- signal is activated, the step 1 decelerates
to stop and changes into step 2� It escapes the limit in reverse and stops after detecting the limit signal
activated in low speed by the irregular operation

of the step 2�
If the start position of the home search is in the limit (Fig. 1, A point), step 1 is not operated and step 2 starts.
It reversely moves a certain position in step 4 and ends escaping the limit�
