Question

When more than one brushless DC motor
drive is connected to the same mains power,
and one of them is ON during operation.

When applying power to one of the brushless
DC motor drive, the charge current of the
capacitors may cause voltage dip. The
brushless DC motor drive may be damaged
when over current occurs during operation.
