ZERO SPEED DELAY
(see above)
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 accurately the rotor
position.
No Zero Speed Delay
The drive receives a stop command and decelerates along a ramp. When the motor actual speed falls
below the value of parameter
, the speed controller is switched 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 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
magnetised 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.
22.07
ABOVE SPEED LIM
(see above)
Defines the supervision limit for the actual speed. See also parameter
, bit 10.
0…30000 rpm
Supervision limit for actual speed.
Speed controller
switched off: Motor
coasts to stop.
Speed controller remains live.
Motor is decelerated to true 0
speed.
No Zero Speed Delay
