No zero speed delay
the drive receives a stop command and decelerates along a ramp. when the motor actual speed falls below an internal limit(called zero speed), the speed controller is seitched off. the inverter modulation is stopped and the motor coasts to standstill.
with zero speed delay
the drive receives a stop command and decelerates along a ramp. when the actual motor speed falls below an internal limit(called zero speed), the zero speed delay function activates. during the delay the functions keeps the speed controller live: the inverter modulates, motor is magnetised and the drive is ready for a quick restart.
