H8PS

Setting Resolution and Rotation

Direction

One of three resolutions can be selected for the Encoder connected

to the H8PS: 256, 360, or 720. The resolution and display angle are

set here.

Setting the Origin

The origin of the Cam Positioner is set to match the origin of the

machine (Encoder). The same origin is used for all banks.

(The bank function is supported only for 16-/32-output models.)

Turn OFF the power supply.

Set the display angle and the

Encoder resolution.

Check the rotation direction of the machine (Encoder).

Connect the machine (Encoder) and turn ON

the power supply.

End of preparations.

Open the front cover at the lower part of the H8PS and

set pins 3 and 4 on the DIP switch.

Note: Changes to DIP switch settings are enabled when the power is turned ON.

Note: Default setting.

Turn ON the power supply.

Turn the Encoder in the actual direction of operation and

confirm that the rotation display monitor turns clockwise.

If the monitor turns counterclockwise, turn OFF the power supply

and change pin 1 on the DIP switch to CCW.

Rotation Display Monitor

(See note.)

Note 1: Default settings are shown in reverse type.

Note 2: When using an Encoder with a resolution of 256, displaying 360

directly is not possible. The H8PS thus provides a convenient

setting that enables converting the display and settings to 360

when using an Encoder with a resolution of 256. When using a

360

° display, however, some angles will not be displayed.

(See note 2.)

Example: Setting the Present Angular Position of 150° to 0°

Change the mode.

Set the machine to its origin.

Specify the origin.

End

Turn the machine (Encoder) to the position of the desired

origin (150

° in this example).

Press the ORIGIN Key. (See note.)

In approx. 1 s, the present angular position display will

change to 0

° and the previous display will return.

Set the mode switch to PRGM.

Set the programming mode switch to TCH.
