Emergency evacuation
13.1
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
In the event of a mains failure, the mains supply must provide the following voltage to the frequency
inverter:
•
230 VAC to feed L1 and L2
The ZETADYN 4 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:

+ Electromechanical brakes power consumption
+ Other consumers (car light,
