1.7 Selection criteria
20
Select the variable frequency drive according to the supply voltage U
the supply system and the rated operational current of the assigned motor.
The motor'scircuit configuration (Δ / ) must be selected to match the
supply voltage.
The variable frequency drive's rated output current I
equal to the rated motor current.
Figure 9: Selection criteria
When selecting the drive, the following criteria must be known:
• Mains voltage = rated voltage of the motor (e.g., 3~ 400 V)
• Type and model of motor (e.g., three-phase asynchronous motor)
• Rated motor current (recommended value – dependent on the circuit
type and the supply voltage).
￫
The DB1 series variable frequency drives are designed for instal-
lation on external cooling surfaces.
The rated currents I
of 60 °C. Cooling must be designed accordingly during project
planning (￫ section 3.3.2, "Cooling measures", page 43).
The lower the ambient temperature, the more favorable the
cooling ratios.
