menu 6
: Stop mode
Adjustment range :
Factory setting :1
0 (Coast) (FrEE): Freewheel stop.
The power bridge is deactivated as soon as the stop
command is given.
The drive cannot receive another run command for 2 s, the
motor demagnetisation time.
The display indicates "rdY" 2 seconds after the stop
command. The machine stopping time depends on its inertia.
1 (Ramp) (rAMP): Stop on deceleration ramp.
The drive decelerates the motor according to the
deceleration mode chosen in parameter 2.04.
One second after the stop, the display indicates "rdY".
2 (Ramp + DC) (rP.dC): Stop on deceleration ramp with DC
injection for a set period of time.
The drive decelerates the motor according to the deceleration
mode chosen in parameter 2.04.
When zero frequency is reached, the drive injects DC with an
amplitude which can be set in parameter 6.06 for a time
defined by parameter 6.07.
The drive then displays "rdY".
3 (DC to 0) (dC-O): Stop by DC injection braking, and
elimination at zero speed.
The drive decelerates the motor by setting a low-frequency
current resulting in almost zero speed, which the drive detects
automatically.
The drive then injects DC with an amplitude which can be set
in parameter 6.06 for a time defined by parameter 6.07. The
drive then displays "rdY". No run command can be taken into
account until "rdY" is displayed.
