(7) CWW-11 drive type
When the drive starts in the CCW direction, the machine origin is detected upon detection of a CW-side
edge of the CCWLM signal.
When the drive starts in the CW direction, the machine origin is detected upon detection of a CCW-side
edge of the CCWLM signal.
The following explanation assumes that the CWIWIW drive starts in the - (CCW) direction.
When the drive starts in the + (CW) direction, the operations symmetrical to those in the CCW
direction are performed to detect the machine origin.
Input a single pulse or a - (CCW) level holding sensor signal to the CCWLM signal.
Allow a signal width of
ms or more to be detected when it passes the sensor at the maximum speed.

In the SCAW process, the stop function after detection of the CCWLM signal is slow stop.
The distance from the CCWLM signal to the system limit in the - (CCW) direction must be sufficient for
slow stop.
