Parameters 199
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 eg with the jogging function.
0…30000 ms
Zero speed delay.
