Note:Cam output precision, however, is 2° max. for Encoder with 256 resolution (P/R).

Note:Although 32-output Models can have 10 steps set for any one output, there must be no more than 160 steps total set for all cam outputs.

Note:The maximum is 1000 r/min when an E6CP-AG5C-C Encoder is connected.

Note:ADV stands for Advance Angle Compensation.

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
(H8PSSOFT-V1, sold separately).
