(5) CWW-4 and CWW-5 drive types
With the CWW-4 or CWW-5 type, the machine origin is detected upon detection of a WCWW and CWW
detection signals.
The CWW-4 or CWW-5 type first executes the WEAW CWIWIW process and then executes the CWIWIW process.
WEAW CWIWIW process of CWW-4 and CWW-5 types
■
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 edges in the symmetrical direction.
Input a single pulse or a - (CCW) level holding sensor signal to the WCWW detection signal.
Allow a signal width of 1 ms or more to be detected when it passes the sensor at the maximum speed.
