Defines the zero speed limit. The motor is stopped along a
speed ramp (when ramped stop is selected) until the defined
zero speed limit is reached. After the zero speed delay, the
motor coasts to a stop.
Zero speed limit.
Defines the delay for the zero speed delay function. The
function is useful in applications where a smooth and quick
restarting is essential. During the delay, the drive knows the
rotor position accurately.
Without zero speed delay:
The drive receives a stop command and decelerates along
a ramp. When actual motor speed falls below the value of
parameter 21.06 Zero speed
