(2) CWW-1 drive type
When the CWIWIW drive starts in the - (CCW) direction
■
With the CWW-1 type in the CCW direction, the machine origin is detected upon detection of a CW-side
edge of the CWW detection signal.
Input a single pulse or a + (CW) level holding sensor signal to the CWW detection signal.
Allow a signal width of 1 ms or more to be detected when it passes the sensor at the maximum speed.

When the CWIWIW drive start direction is the + (CW) direction
■
When the drive starts in the CW direction, the operations symmetrical to those in the CCW direction
are performed to detect edges in the symmetrical direction.
