Functions

Item H8PS-8[] H8PS-16[] H8PS-32[]
Encoder rotation
direction switching
Encoder data can be set with a DIP switch to forward (CW) or reverse (CCW) direction.
Encoder origin
designation
The present display angular
position can be set to 0°
(origin) by pressing the
ORIGIN Key on the front
panel.
The present display angular position can be set to 0° (origin)
by using the origin input terminal or the ORIGIN Key on the
front panel.
Note: All banks use the same origin.
Angle display switch Converts the Absolute Encoder value display from 256 divisions/revolution to 360°/
revolution.
Rotation display monitor Graphically displays the Encoder rotational angular position.
Teaching function Sets the cam output ON/OFF angle based on actual machine (Encoder) operation.
Pulse output Outputs a preset number of pulses per Encoder rotation. It also sets the pulse output start
angle.
Switching the angle and
speed displays
Displays both the present angular position and the number of Encoder revolutions (speed) in
Run Mode. Switches back and forth between the main display showing the present angular
position with the sub-display showing the speed and the main display showing the speed with
the sub-display showing the present angular position.
Bank function --- Enables the entire cam program to be changed at one time by
switching banks (0 to 7).
The bank that is running can be switched using the bank input
terminal or the BANK Key on the front panel.
Also enables programs to be copied between banks.
Advance angle
compensation (ADV)
function
Automatically advances the ON/OFF angle of cam outputs in proportion to machine
(encoder) speed to compensate for the delay in timing of ON/OFF operation. ADV values
can be set individually for 7 cam outputs.
Speed alarm output A specified cam output can be used as an Encoder speed alarm output.
The function can output upper and lower limit speed alarms.
All protection function Disables all key and switch operations in Run Mode to prevent incorrect or unauthorized
operation.
Cam protection function Prohibits program changes at the cam output level. Any cam numbers can be protected.
Step number limit Limits the number of steps that can be set per cam output. Prohibits incorrect operations
by adding to the program.
Output prohibit --- The start input can be turned OFF in Run or Test Mode to
prohibit cam output.
Note: Use this function carefully for the application because no
cam outputs are provided when the start input is turned OFF.
Support Software
settings
--- Programs can be uploaded or downloaded easily by connecting a
personal computer to the Cam Positioner using a USB Cable
(Recommended USB Cables: ELECOM CO.Ltd. U2C-MF20BK)
and the Support Software (H8PS-SOFT-V1, sold separately).
