4 The outline of motor control
16
When you set H.P to direction CW, you have to set motor position to CCW side
against origin sensor, then move motor from CCW to CW side by operation switch
JOG CW or START + JOG CW.
Once detect the origin point, motor stopped suddenly, origin point procedures
finished.
Then the position of pulse data is memorized and the direction approaching a sensor
is also memorized. (In the case of the above figure the CW direction)
This way is applicable also to the detection in the case of using HP sensor as CWLS
or CCWLS. (In that case, input CWLS or CCWLS also into HPLS)

[METHOD B]
The following example is the case that the direction of the origin point detection is
CW. The start direction of the origin point detection set in the opposite direction of
the direction of the origin point detection.
(You can set at “ Page6 Home position setting” (Page 24))
(a). In case of start position is in CW side against origin point
(b). In case of start position is in CCW side against origin point
If a starting point sensor is detected, it will pass at first. And it will stop, if it passes

2. Detect the origin point then back
to CW side at low speed.
1. It starts present speed H, M, L.
3. Again detect the origin point at low speed.

2. Detect the CCW limit switch then back to CW side.
1. It starts present speed H, M, L.
3. Detect the origin point then goes to
CCW side at low speed.

4. Again move to CW side and detect
the origin point and stop.
