Corrective Actions for Errors
For fatal errors in the Programmable Multi-Axis Controller, take the following corrective actions depend-
ing on the nature of the error.
5-3-1
Fatal Errors in the Programmable Multi-Axis Controller
Details
Cause
Corrective action
Power supply error The unit’s input power is not supplied.
Check the following items and adequately sup-
ply adequate 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 outside
the permissible range.
Check the following items and adjust the volt-
age so that it falls within the permissible range.
• Is the power voltage within the specification
range?
• Is the power capacity sufficient?
• Is the power supply failing?
The power supply unit of the Programma-
ble Multi-Axis Controller failed.
If the error still persists even after the above
corrective actions have been taken, replace
the Programmable Multi-Axis Controller.
Watchdog timer
error
Intrusion of noise
Check the FG, power supply lines, communi-
cations lines, and other noise entry paths, and
implement noise-related countermeasures as
required.
Software watchdog trip caused by the
insufficient task processing time or failed
task interruption.
For details, refer to the following manuals.
• Power PMAC User’s Manual
• Power PMAC Software Reference Manual
A momentary power interruption occurred
in the Programmable Multi-Axis Controller
during operation caused by a momentary
power interruption of the unit’s power sup-
ply.
Take appropriate measures to ensure that the
specified power with the rated voltage and fre-
quency is supplied in places where the power
supply is unstable.
The Programmable Multi-Axis Controller
failed.
Replace the Programmable Multi-Axis Control-
ler.
Initial process error Intrusion of noise
Check the FG, power supply lines, communi-
cations lines, and other noise entry paths, and
implement noise-related countermeasures as
required.
The Programmable Multi-Axis Controller
failed.
Replace the Programmable Multi-Axis Control-
ler.
