I 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.
