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.
