Low-voltage during acceleration (LvA)
DC bus voltage is lower than Pr.06-00 setting value during acceleration.
The load is too large -
Reduce the load.
Increase the drive capacity.
Increase the acceleration time.
Improve power supply condition. Check input supply voltage.
Check rectifier using multimeter.
