Features
Models with 8, 16, or 32 Outputs
The lineup includes Models with 32 outputs in a compact 1/4-DIN
size. Using the optional Parallel Input Adapter (Y92C-30) enables
expanding to up to 64 outputs for one encoder to support anything
from a simple positioning application to a large-scale system.
Simple Programming
The programming method is designed based on a one key-one
action concept for settings that could not be simpler. Both initial
settings and factory adjustments are effort-free.
Large, Backlit Negative LCDs
Large LCDs, red for the process value and green for set values, show
a wealth of operation information, making operating status visible at
a glance.
High Speed Up To 1,600 r/min
High Precision Up To 0.5° (at 720 Resolution)
High-speed, high-precision applications can be easily handled and
productivity increased.
Bank Function for Multi-product Production
Up to eight different programs can be registered in advance to
enable fast and easy switching between products (16/32-output
Models only).
USB Communications for Easy Setting from
a Computer
Optional Support Software can be used to enable programming from
a personal computer via USB communications. Programs can be
easily copied, saved, printed, and much more.
Speed Display and Speed Alarm Output
Both the speed (rotations/minutes) and present angular position can
be displayed at the same time. Alarm outputs can be produced for
both upper and lower speed limits.
Advance Angle Compensation Function to
Compensate for Output Delays
The advance angle compensation (ADV) function automatically
advances the ON/OFF angle of 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.
Pulse Output for Timing Control
The number of pulses per rotation and the pulse output start angle
can be set to enable operations like adjusting timing with a PLC or
outputting to a rotation meter.

Safety Precautions for Encoders
■Precautions for Correct Use
•Do not subject the E6CP Encoder to oil or water.
•The Encoder consists of high-precision components. Handle it with
utmost care and do not drop it, otherwise malfunctioning may
result.
•When connecting the shaft of the Encoder with a chain timing belt
or gear, connect the chain timing belt or gear with the shaft via a
bearing or coupling as shown in the following diagram.
•If the decentering or declination value exceeds the tolerance, an
excessive load imposed on the shaft may damage or shorten the
life of the Encoder.
•Do not place excessive loads on the shaft if the shaft is connected
to a gear.
•The tightening torque must not exceed the value given in the table
at the right when the Rotary Encoder is mounted with screws.
•Do not pull wires with a force greater than 29.4 N while the Rotary
Encoder is secured and wired.
•Do not subject the shaft to shock. Therefore, do not strike the shaft
or coupling with a hammer when inserting the shaft into the
coupling.
•Make sure there is no foreign matter in the Connector before
connecting it to the Encoder.

Refer to Safety Precautions for All Counters.
■Precautions for Safe Use
Observe the following items to ensure the safe use of this product.
Environmental Precautions
•Store the H8PS within specified ratings. If the H8PS has been
stored at temperatures −10°C or lower, let it stand for 3 hours or
longer at room temperature before turning ON the power supply.
•Use the H8PS within the specified ratings for operating temperature
and humidity.
•Do not operate the H8PS in locations subject to sudden or extreme
changes in temperature, or locations where high humidity may
result in condensation.
•Do not use the H8PS in locations subject to vibrations or shock.
Extended use in such locations may result in damage due to stress.
•Do not use the H8PS in locations subject to excessive dust,
corrosive gas, or direct sunlight.
•Install the H8PS well away from any sources of static electricity,
such as pipes transporting molding materials, powders, or liquids.
•The H8PS is not waterproof or oil resistant.
Do not use it in locations subject to water or oil.
•The life expectancy of internal components may be reduced if the
H8PS is mounted side-by-side.
•Do not use organic solvents (such as paint thinner or benzine),
strong alkaline, or strong acids because they will damage the
external finish.
Usage Precautions
•Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
•Pay careful attention to polarity to avoid wrong connections when
wiring terminals.
•Do not connect more than two crimp terminals to the same
terminal.
•Use the specified wires for wiring.
Applicable Wires
AWG24 to AWG18 (cross-sectional area of 0.208 to 0.832 mm2)
Solid or twisted wires of copper
•Do not connect loads that exceed the rated output current. The
output elements may be destroyed, possibly resulting in short-
circuit or open-circuit faults.
•Always connect a diode to protect against counterelectromotive
force when using an inductive load. Counterelectromotive force
may destroy output elements, possibly resulting in short-circuit or
open-circuit faults.
•Use the specified cables to connect outputs.
•Do not install input lines in the same duct or conduit as power
supply or other high-voltage lines. Doing so may result in
malfunction due to noise. Separate the input lines from high-
voltage lines.
•Internal elements may be destroyed if a voltage outside the rated
voltage is applied.
•Maintain voltage fluctuations in the power supply within the
specified range.
•Use a switch, relay, or other contact so that the rated power supply
voltage will be reached within 0.1 s. If the power supply voltage is
not reached quickly enough, the H8PS may malfunction or outputs
may be unstable.
•Do not turn OFF the power supply when changing or deleting
settings. The contents of the EEPROM may be corrupted.
Tighten terminal screws to a torque of 0.80 N·m so that
they do not become loose.
Minor fires or malfunction may occasionally occur.
For 16- and 32-output Models, leave the protective label
attached to the H8PS when wiring. Removing the label
before wiring may occasionally result in fire if foreign
matter enters the Unit.
Remove the label after the completion of wiring to ensure
proper heat dissipation. Leaving the label attached may
occasionally result in fire.
Do not disassemble, modify, or repair the H8PS or touch
any of the internal parts. Otherwise, minor electric shock,
fire, or malfunction may occasionally occur.
Do no allow metal fragments, lead wire scraps, or chips
from processing during installation to fall inside the H8PS.
Otherwise, minor electric shock, fire, or malfunction may
occasionally occur.
Do not touch the terminals when power is being supplied.
For Surface-mounting H8PS, always connect the terminal
cover for after completing wiring. Otherwise, minor injury
due to electric shock may occasionally occur.
!CAUTION

■Precautions for Correct Use
•A cam output will remain ON if the set angles for two steps overlap
for the same cam number.
Step 1: 120° ON → 170° OFF
Step 2: 150° ON → 210° OFF
•A step will produce no output if the ON and OFF angle for the step
are the same.
•The RUN output does not turn ON during programming.
Note: The RUN output turns ON with the timing shown in the diagram,
but it remains OFF when an error occurs. Thus, you can use the
output as a timing signal during operation, including trial
operation.
•Input signals may be accepted, not accepted, or unstable for the
following times when the power supply is turned ON or OFF. Set the
system to allow leeway in the timing of input signals. Approx. 1
second is required from the time the power supply is turned ON
until outputs are made. Refer to the Operation Manual (Cat. No.
Z199) for information on other timing.
•When using 16-/32-output Modules, the operation timing of the
outputs will be as shown below in relation to the ON/OFF timing of
the start input. Refer to Bank Functions (F7/F8/F9) on page 29
when switching banks.
•Do not subject H8PS Connectors (outputs, Encoder) to more than
30 N of force.
•Confirm the waveform of the power supply circuit and install a
surge absorber. Surge or noise applied to the power supply may
destroy internal elements or cause malfunctions.
•Switch the power supply circuit with a device rated at 3.5 A or
higher.
•Inrush current of approximately 3.5 A will flow for a short period of
time when the power supply is turned ON. The H8PS may not start
if the capacity of the power supply is not sufficient. Be sure to use a
power supply with sufficient capacity.
•EEPROM is used as memory when the power is interrupted. The
write life of the EEPROM is 100000 writes. The EEPROM is written
when settings are changed or deleted or when the resolution is
changed.
•Make sure that all settings are appropriate for the application.
Unexpected operation resulting in property damage or accidents
may occur if the settings are not appropriate.
•Connect all negative (−) terminals, COM terminals, and Vs
terminals.
•When using the Y92C-30 Parallel Input Adapter for parallel
operation, do not connect more than two H8PS Cam Positioners to
the same Encoder.

Advance Angle Compensation (ADV)
Function
The advance angle compensation function automatically advances
the ON/OFF angle of cam outputs in proportion to machine
(encoder) speed. As the speed of the machine increases, the system
can be affected by the delay in outputs. If the ADV function is used,
the output delay caused by higher speeds is automatically
compensated.
As shown in the following diagram, ADV function is used to linearly
compensate outputs according to the speed based on the ADV value
setting for a specific speed.
Example: ADV Value Set to 2° at 100 r/min
ADV value can be set independently for cams 1 to 7 (7 total). For the
ADV function, the speed and the amount of angle compensation are
set. If “- - -” is displayed for any setting, the ADV function is disabled.
The setting ranges are given in the following table.
Note: Default settings are shown in reverse type.
The maximum response speed will decrease as shown in the
following table when ADV values are set for 4 cams or more.
Note: Even if the ADV value is set to 0°, the cam must be included in
the number of cams with ADV settings.
1. Set the mode switch to PRGM or TEST.
2. Set cam number 4 with the CAM Keys . (See note.)

Step Number Limit (f5)
With the H8PS, up to 10 steps can be set to turn the output ON/OFF
10 times for each cam. The number of steps that can be set,
however, can be restricted to prevent programming from being added
through operating mistakes. Settings can be made for all cams at
once or each cam individually. The default setting for the Step
Number Limit is 10 steps for all cams.
The maximum number of steps to be set is set using the F5 menu in
the Function Setting Mode.
Display for Collective Settings
The cam number can be set to a on the setting display to set all
cams at once. If the number of steps is displayed as “---” when the
cam number is a, the collective settings for all cams are disabled.
The maximum number of steps to be set is set using the F5 menu in
the Function Setting Mode.
