Precautions for Correct Use
(1) When using the Y92C-30 Parallel Operation Adapter for parallel operation, do
not connect more than two Positioners to the same encoder.
(2) Do not subject the connectors of outputs, encoder on the Positioner to more
than 30 N of force.
(3) Keep the USB cable connector straight when connecting or disconnecting it.
Otherwise the Positioner or connector may be damaged.
(4) 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.
(5) Switch the power supply circuit with a device rated at 3.5 A or higher.
(6) Inrush current of approximately 3.5 A will flow for a short period of time when
the power supply is turned ON. The Positioner may not start if the capacity of
the power supply is not sufficient. Be sure to use a power supply with sufficient
capacity.
(7) EEPROM is used as memory when the power is interrupted. The write life of
the EEPROM is 100,000 writes. The EEPROM is written when settings are
changed, settings are deleted, or the resolution is changed.
(8) 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.
(9) Inputs 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. Approximately 1 second is required from
the time the power supply is turned ON until outputs are made.
For information on other timing, refer to "Appendix D Operation Timing Chart"
in this manual.

(10) If you use the output cable, connect the minus (−) terminal and all of the COM
terminals. For a PNP output, connect all Vs terminals. If you do not connect all
of the terminals with the same name, the current will be concentrated on the
connected terminals and the ratings of the parts may be exceeded.
