The starting current, will be 6-8 times higher than the
motor's rated current because the motor is at rest.
Those starters reduce or diminish this inrush starting
current are called electrical soft starters.
Soft start is one of the facilities available in VVVF
drives. The other facilities are providing higher starting
torque, speed variation, constant torque maintenance soft
stop etc. Simply saying VVVF drive take care of starting
control, speed control, protection control, forwarding,
reversing control and stopping.
