Evacuation through UPS with minimum power
Information - Evacuation through UPS with minimum power
•
Load-dependent starting, cannot be optimized
•
Evacuation only possible in the direction of the pulling load
•
Positioning is carried out load dependent; that means step formation could occur.
Calculation of the UPS
The required UPS 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 for UPS operation with reduced power (ask
motor manufacturer)
=
Real power UPS [W]
Information
The shaft ef
fi
ciency has a decisive in
fl
uence on the required power of the UPS performance.

In case of a voltage drop (power failure) the inverter is informed by activating the congured input with
24 VDC that a switchover must be made to parameterset 2.
(3) Inform the open loop control about the permissible direction of travel (optional):
