P2.5 Q
UICK STOP MODE
Quick stop is activated through the input signal defined in P5.14 (or P5.15).
Signal low (or high) forces the drive to stop, ramping down with the time defined in P4.9. The
ramp to zero is continued also in case the signal returns high (or low).
This parameter defines the mode Quick stop is managed.
0: Signal level
Quick stop is set when the signal is low (signal defined in P5.14) or high (signal defined in
P5.15).
It is reset when the drive has reached stop condition and the signal is restored to normal level.
How the drive in AUTO mode actually restarts the motor depend on logic set in P2.1.
If P2.1 = 1 or 3, a new rising edge on Start signal is needed.
If P2.1 = 0 or 2, the drive restarts immediately if Start signal is high.
In MANUAL mode it depends on logic set in P2.6.
If P2.6 = 0, the drive restarts immediately if Start command is still activated.
If P2.6 = 1, a new rising edge on Start command is needed.
1: Signal edge
Quick stop is set on falling edge (signal defined in P5.14) or rising edge (signal defined in P5.15)
of the signal.
It is reset when the drive has reached stop condition and the Start signal (Start command on
operator panel in MANUAL) is low, independently from the level of Quick stop signal.
Quick stop condition can be diagnosed through ASi input. It is also signalled by Alarm 63.

TART MODE
0: Level
Once the drive is started in Manual mode, it will automatically resume Run condition after a
fault or a power loss (if ASi voltage is kept up).
It will restart also after a Quick Stop, if P2.5 = 0.
1: Edge
Once the drive is started in Manual mode, a new start is prevented after a fault, a power loss
or a Quick Stop. The previous Run command must be canceled by Stop button, to enable a new
start.
