13.3. EMERGENCY EVACUATION OPERATION
ADrive is capable of performing an automatic evacuation by driving the motor with connection
of a set of batteries or a 1-phase 230Vac UPS in case of a mains power failure.
Evacuation operation with back-up power is supported only for closed-loop operation.
This feature is available in version V2.5 and higher of processor board.
13.3.1. General information:
For emergency evacuation in case of power failure, an external power supply is required to
supply the components in the elevator system (elevator control unit, mechanical brakes, retiring
cam, door operator …) with sufficient power. Thus, a UPS is needed in all applications.
Therefore, there are two ways of supplying back-up power to the elevator control system for
evacuation operation with ADrive inverter.
1st way
For motor power: Min. 60Vdc battery voltage
For other units (except motor power): 1-phase 230Vac UPS
2nd way
1-phase 230Vac UPS (for whole system including the motor power)
The selection of power supply for evacuation operation depends on the type of the evacuation
method (evacuation in the lower load direction or command direction given by the lift
controller).
If the evacuation operation is performed in the lower load direction, 60Vdc battery back-up
supply will be sufficient.
If the evacuation operation is performed in the command direction given by the lift controller
(not in the lower load direction), because the required power for moving the car is increased, a
battery pack with higher voltage (72-120Vdc) or a 1-phase 230Vac UPS with a sufficient power
is needed.
13.3.2. Required back-up power supplies:
In evacuation operation, two dc supplies must be provided to the inverter as follows:
The connection of the back-up power has to be carried out in accordance with the speci cations
described in the Chapter 13.3.5.
The power circuit supply:
This provides just the power for the motor during evacuation operation. The power circuit of the
inverter can either be supplied by batteries or by a UPS.
This supply must be connected to the input terminals L1 and L3.
The back-up power connected to the inverter is set by the parameter “12.1 Battery voltage”.
The control circuit supply (24Vdc):
This provides just the power for control circuits when the AC supply is not present. This supply
must be permanently connected to the +/-24V input terminals on the inverter.
