Remedy
Increase the power supply capacity.
Eliminate the cause of the failure of
the electromagnetic contactor on the
main circuit power supply, and then
turn ON the power again.
Review the power supply conditions
and prevent momentary power
interruption. Alternatively, increase
the Momentary Hold Time (3509 hex)
setting.
Make sure that the phases of the
power supply are set correctly before
you connect them.
Replace the Servo Drive.
