Emergency evacuation
12.1
Evacuation with 1-phase mains supply 230V AC
Due to the low power requirements of a synchronous drive, it is possible to carry out an evacuation trip
in the motoric and generatoric direction.
Due to the high level of magnetization current, emergency evacuation with a single-phase mains
supply with asynchronous motors does not make sense.
Information - Characteristics of evacuation with single-phase mains supply:
•
Evacuation in motoric and generatoric direction
•
Load-independent starts
•
Load-independent stopping
•
Flush stopping
If there is a mains failure, the mains supply must provide the following voltage to the inverter:
•
230 VAC to feed L1 and L2
The frequency inverter analyses the load ratio between the car and the counterweight during every
start.
The control system starts the evacuation trip by activating:
•
Controller enable
•
Direction default
•
Speed default
Size of the voltage supply
The required performance consists of the following:
Electronic frequency inverter power consumption
+ Control systempower consumption
+ Electromechanical brakes power consumption
+ Other consumers (car light,
…
) power consumption
+ Motor power consumption during motoric operation with suf

Real power [W]
Information
The shaft ef

ciency has a decisive in
fl
uence on the required power of the single-phase mains supply.
