: Stop mode
Coast:
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 for 2 seconds,
the time required for motor demagnetisation.
After this stopping time, the drive is «ready». The machine
stopping time depends on its inertia.
Ramp (#):
Stop on deceleration ramp.
The drive decelerates the motor according to the deceleration
mode chosen in parameter
Spd.08
.
One second after the stop, the drive is «ready».
Ramp + DC (
):
Stop on deceleration ramp with DC injection.
The drive decelerates the motor according to the deceleration
mode chosen in parameter
Spd.08
.
When zero frequency is reached, the drive injects DC current
for 1 second.The drive is «ready».
Zero speed DC (
):
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 current for 1 second. No run command
can be taken into account until the drive is «ready».
Timed DC (
):
Stop on DC injection.
The drive decelerates the motor by imposing a current for
1 second. No run command can be taken into account until the
drive is «ready».
Note:
In closed loop mode (
), the «Ramp + DC», «Zero
speed DC» and «Timed DC» stop modes are equivalent to the
«Ramp» stop mode.
