Application of the Cam Switch (Cam Switch Mode)
The following ladder program illustrates the basic setting of the cam switch function.
Connect the encoder with a resolution of 360 pulses.
Use output relays 0600 through 0603.
Output relay 0600: Turns ON within the range 30° to 90°
Output relay 0601: Turns ON within the range 45° to 80°
Output relay 0602: Turns ON within the range 70° to 150°
Output relay 0603: Turns ON within the range 120° to 270°
1) Sets "0600", which is the initial number of relays used for the cam switch function, to
DM1400 and sets twice the number of pulses for one encoder rotation (360 x 2 = 720) to
DM1402.
2) Specifies the preset angles at which output relays 0600 through 0603 turn ON/OFF.
3) Sets the input time constant for input relay 0004 to 10 µs.
4) Sets the input time constant for input relay 0006 to 10 µs.
5) Sets the input time constant for input relay 0008 to 10 µs.
6) The cam switch operation starts when input relay 0000 turns ON.
7) The cam switch operation stops when input relay 0001 turns ON.
