06.01
: Stop mode
Adjustment range : Coast (0), Ramp (1),
Ramp + DC (2), Zero speed DC (3),
Timed DC (4)
Factory setting : Ramp (1)
Format: 8 bits
Coast (0):
The drive stops in freewheel mode.
The power bridge is deactivated as soon as the stop command
is given.
The drive cannot receive another run command during the
time programmed in 06.63 , the motor demagnetisation time.
After this stopping time, the drive is «ready». The machine
stopping time depends on its inertia.
Ramp (1):
Stop on deceleration ramp.
The drive decelerates the motor according to the deceleration
mode chosen in parameter 02.04 .
One second after the stop, the drive is «ready».
Ramp + DC (2) ( ):
Stop on deceleration ramp with DC injection for an imposed
period of time.
The drive decelerates the motor according to the deceleration
mode chosen in parameter 02.04 .
When zero frequency is reached, the drive injects DC with a
magnitude which can be set in parameter 06.06 for a time
defined by parameter 06.07 .
The drive is «ready».
Zero speed DC (3) ( ):
Stop by braking using low frequency current injection, then DC
injection at zero speed.
The drive decelerates the motor by imposing a low frequency
current until it reaches almost zero speed, which the drive
detects automatically.
The drive then injects DC with a magnitude which can be set in
parameter 06.06 for a time defined by parameter 06.07 . No
run command can be taken into account until the drive is
«ready».
