9.2.3.1 Starting/Stopping a Cyclic Electronic Cam
If an electronic cam operates cyclically, the slave axis of the electronic cam moves in accordance with
electronic cam data when the master axis of the electronic cam moves. Electronic cam data defines
only one cycle. The relation between the positions of a master axis and the positions of a slave axis is
the repeated extension of electronic cam data.

 Starting a cyclic electronic cam
The steps of starting a cyclic electronic cam are as follows.
1. In T1, D1846 bit 13=ON, cyclic electronic cam is enabled.
2. After the initialization interval of T2, M1812=ON to indicate the completion of electronic cam
initialization.
3. In T3, cyclic operation starts after M1812=ON. Slave executes with Master constantly according
to the electronic cam data.
4. At the same time, CLR0 outputs according to the synchronized output range. When M1813=ON,
an electronic cam cycle is completed. User has to reset the flag for indicating the completion of
other electronic cam cycles.
