HOW TO USE THE
BASIC FUNCTIONS
3.3 DIP Switch Setting
3.3.1 Selecting the Encoder Resolution
The Encoder to be connected to the H8PS Cam Positioner can be chosen from among three resolutions
(256/360/720).
In this step the resolution and display angle are designated.
■ Operation
Make sure that the power is off.
Open the front cover at the lower part of the H8PS and set pins 3 and
4 on the DIP switch.
* The factory setting is indicated by white characters on a black background.
If an Encoder with a resolution of 256 per rotation is used, angles cannot be displayed using 360°
notation if the Encoder outputs are used as they are. To facilitate operation, the H8PS Cam Positioner
has a function for displaying/setting the angles using 360° notation even if a 256 resolution Encoder is
connected. With this type of Encoder, however, there are angles that cannot be displayed if 360°
notation display is selected.
• When operating the DIP switch, use a tip of tweezers or a tool with a tip approximately
0.8 mm in width.
• The DIP switch settings are read to the H8PS Cam Positioner when the power is turned on.
• When the resolution selection is changed and read, all types of information including all the
programs, the data set in the function setting mode, and the origin information are cleared
(initialized). This does not happen if just the display angle setting is changed on a 256 res-
olution Encoder.
• If the all protection function is active (Refer to "3.11 All Protection Function"), changing the
settings is not allowed and any attempt to do so is disregarded.
• Pin 2 on the DIP switch is not used and must remain in the factory setting.
