9 Electronic Cam
signals as input signals of Master).
(6) Set up lower bound of CAM sync output D1839, D1838=20000 and upper bound D1843,
D1842=30000. Between Master position 20000~30000 (can be monitored by D1862), CLR0
is ON. However, the CLR LED on the MPU will not respond to it. To monitor CLR signal,
users can connect CLR0- to 0V, connect CLR0+ to Xn input contact, connect S/S2 to 24V,
and then monitor the ON/OFF status of Xn input.
2. Set M0 to ON to enable cyclic electronic cam. When M0 is rising-edge triggered, Master starts
to receive the variable speed pulses from Y axis, and Slave operates according to the above
electronic cam data curve. In addition, CLR0=ON during Master position 20000~30000.
3. Reset M0.

When D1846=H2000, Y axis variable speed
operation executes.
When M0 is rising-edge triggered, set
D1846=H2000 to enable cyclic E-CAM
When M0 is falling-edge triggered, cyclic E-CAM
stops.
