CWIWIW process
■
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 into the CWW detection signal a sensor signal that is periodically generated such as by a slit
of a rotary axis.
Allow a signal width of 1 ms or more to be detected when it passes the sensor at the speed (CSPD)
in the CCWSTAWT SCAW process.
