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.)
Example: Setting the Present Angular Position of 150° to 0°
Turn OFF the power supply.
Change the mode.
Set the mode switch to PRGM.
Set the display angle and the
Encoder resolution.
Set the programming
mode switch.
Set the programming mode switch to TCH.
Open the front cover at the lower part of the H8PS and
set pins 3 and 4 on the DIP switch.

Turn the machine (Encoder) to the position of the desired
origin (150° in this example).
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.
Check the rotation direction of the machine (Encoder).
Turn ON the power supply.
STEP
CAM
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.
Specify the origin.
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.
