Evacuation mode
The drive uses the evacuation mode (evacuation speed) during a rescue operation.
The evacuation mode can be enabled with parameter
EVACUATION MODE.
Before enabling the evacuation mode, make sure that the elevator car is stopped.
With parameter
EVACUATION AUTO, you can select whether the evacuation
of the elevator car is manual or fully automatic.
Manual evacuation
– the drive first waits for the elevator controller to give the start
up or start down signal. The evacuation travel is then conducted in the corresponding
direction.
Automatic evacuation
– the drive operates as follows:
1. Drive waits for the elevator controller to give the start up or start down signal.
2. Drive activates a start command in the upward direction for 2 seconds and checks
the actual torque.
3. Drive is stopped for 2 seconds.
4. Drive activates the start command in the downward direction.
5. Drive monitors and stores the downward operation torque.
6. Drive compares the torque in both directions and automatically issues a start
command in the direction of the lighter load.
Automatic/recommended evacuation
– the drive uses the pre-stored direction
information and starts in the direction of lighter load.
When the elevator operates in the evacuation mode, the drive uses parameter
EVACUATION SPEED as the speed reference and parameters
EVAC MODE
ACC and
EVAC MODE DEC for acceleration and deceleration, respectively.
Jerks are disabled in the evacuation mode.
