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.
Note:
If you use a value below the default, make sure the
drive is able to stop.

Zero speed limit.
See par.
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.
0 ms
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
, inverter modulation is
stopped and the motor coasts to a standstill.
With zero speed delay:
The drive receives a stop command and decelerates along a
ramp. When actual motor speed falls below the value of
parameter
, the zero speed delay
function activates. During the delay the function keeps the
speed controller live: the inverter modulates, motor is
magnetized and the drive is ready for a quick restart. Zero
speed delay can be used e.g. with the jogging function.
