6 - Quick stop active
Emergency stop
The drive performs a fast stop, after which restarting will only be possible once the drive has changed to the "Switch on disabled" state.
During fast stop, the drive is unlocked and power is supplied to the motor.
The configuration parameters cannot be modified.
The condition for transition 12 to the state "2 - Switch on disabled" depends on the value of the parameter "Quick stop option code" (QSTD):
• If the "Quick stop option code" parameter has the value 2, the drive stops according to the fast stop ramp and then goes into the state
"2 - Switch on disabled".
• If the "Quick stop option code" parameter has the value 6, the drive stops according to the fast stop ramp and then remains in the
state "6 - Quick stop active" until:
- A "Disable voltage" command is received
- Or the STOP key is pressed
- Or there is a freewheel stop command via the terminals

The drive function is activated or deactivated according to the type of reaction configured in the fault management parameters.
