This parameter should not be higher than the high operating current of the power supply, otherwise it may cause damage to the power supply. You should choose a power supply with a higher current or equip the motor with a soft start protection circuit to absorb the surge current.\u003cbr\u003e\n(Power formula) Voltage X
