LED Error Indicators Section 11-3
❍ ● ❍ ● ● ● ●
CPU error The CPU Unit has stopped
because the watchdog timer
turned ON. Check that the CPU Unit and
PCU are mounted securely,
and reset the power supply.
If the same error occurs repeat-
edly, replace the CPU Unit or
PCU. A CPU bus error has been
detected.
The CPU Unit did not perform
END refresh processing within
the cyclic service monitor time. In the system settings for the
CPU Unit, check that the END
refresh has not been disabled.
If it has been disabled, enable
it, and reset the power supply.
Increase the CPU Unit’s cycle
monitor time, and reset the
power supply again.
Even if this error is detected, it
will not affect PCU operation.
Also, once END refresh is
enabled, the ERH LED indica-
tor will turn OFF.
A fatal error occurred in the
CPU Unit. Remove the cause of the error
at the CPU Unit. Once the
cause is removed, normal sta-
tus will be restored, and the
ERH LED indicator will turn
OFF.

Parameters destruc-
tion When using the axis parame-
ters saved in the PCU, the
parameters saved in flash
memory have been lost. It is
possible that, while saving to
flash memory, the PCU’s power
supply was interrupted, there
was noise, or there was an
error in flash memory. In this condition, only the data
transfer (read and write) and
data save operations can be
performed. The PCU’s axis
parameters and data are all
returned to their default values.
After transferring the parame-
ters again for all axes, save the
parameters and either reset the
power supply or restart the
PCU. If the error persists,
replace the PCU.
❍ ❍ ● ● ● ● ●
Data destruction The following data saved in
flash memory has been lost:
Zones, positioning sequences,
speeds, acceleration/decelera-
tion times, positions, dwell
times.
It is possible that, while saving
to flash memory, the PCU’s
power supply was interrupted,
there was noise, or there was
an error in flash memory.
