■ 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.
