Omron H8PS Manual

Cam Positioner H8PS 21
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.)
