Tighten the terminals to the correct tightening
torque.
Too much fluctuation in the drive input
power voltage.
•
Measure the voltage from the drive input power.
•
Make the drive input power stable.
There is unsatisfactory balance between
voltage phases.
•
Make the drive input power stable.
•
Disable phase loss detection.
The main circuit capacitors are
unserviceable.
•
Make sure that the capacitor maintenance time in
monitor
U4-05 [CapacitorMaintenance]
is less
than 90%.
•
Replace the main capacitors if
U4-05
is more
than 90%. Contact Yaskawa or a Yaskawa
representative to replace the main capacitors.
Make sure that there are no problems with the drive
