Operation
The H8PS Cam Positioner receives angle signal inputs from the Encoder, and outputs the preset ON/OFF angles as control signals (cams number
1 to 8).
Program Example
Classifications Functions
Encoder rotational direction switch
Encoder data revolutions can be set to clockwise or counterclockwise.
Encoder origin designation
The process display angle can be set to the origin as 0
°
at the press of a button.
Angle display switch
The unit can convert the display of absolute encoder values 256 divisions/revolution to 360
°
/revolution.
Rotation display monitor
Graphic display of encoder rotational angle position.
Teaching
The unit can set the ON/OFF angle from actual operation of the machine.
Monitor contents
Process value display (character height: 11 mm), output display, settings display, set cam number dis-
play, mode display, revolution display, operation step display, and error message display.

Operation Example
Note: 1. When the setting angles for STEP 1 and STEP 2 of same output are overlapped, the operation is as follows:
2. The operating output RUN OUT" does not turn ON during programming. The operation output turns ON with the timing shown in
the diagram, but it remains OFF when an error occurs. Thus, you can use the output as a timing signal during operation, including
test runs.
