Fatal Errors in the Motion Controller
For fatal errors in theMotion Controller, take the following corrective actions depending on the nature
of the error.
Description Cause Corrective action
Power supply er-
ror The unit’s input power is not supplied. Check the following items and adequately supply power to
the unit.
•
Is the power turned ON?
•
Is the power cable wired correctly?
•
Is the power cable free of damage?
The unit’s input power voltage is out-
side the permissible range. Check the following items and adjust the voltage so that it
falls within the allowable range.
•
Is the power supply voltage within the specified range?
•
Is the capacity of the power supply sufficient?
•
Is the power supply failing?
The power supply unit of theMotion
Controllerfailed. If the error still persists even after the above corrective ac-
tions have been taken, replace the Programmable Multi-Ax-
is Controller.

error Intrusion of noise Check the FG, power supply lines, communications lines,
and other noise entry paths, and implement noise-related
countermeasures as required.
Illegal user program Refer to 5-3-3 Initialization of the Motion Controller on page
5-7, and execute re-initialization.

A momentary power interruption occur-
red in the Programmable Multi-Axis
Controller during operation caused by
a momentary power interruption of the
unit’s power supply. Take appropriate measures to ensure that the specified
power with the rated voltage and frequency is supplied in
places where the power supply is unstable.

ror Intrusion of noise Check the FG, power supply lines, communications lines,
and other noise entry paths, and implement noise-related
countermeasures as required.

5-3-2 Non-fatal Errors in the Motion Controller
For fatal errors in the Motion Controller, take the following corrective actions depending on the nature
of the error.
