Parameters 155
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.
0…30000 ms
