Select the variable frequency drive according to the supply voltage U
the supply system and the rated operational current of the assigned motor.
The circuit type (Δ / ) of the motor must be selected according to the
supply voltage.
The variable frequency drive's rated output current I
equal to the rated motor current.

Figure 12:Selection criteria
When selecting the drive, the following criteria must be known:
• Mains voltage = rated operating voltage of the motor (e. g. 3~ 400 V),
• Type of motor (e.g., three-phase asynchronous motor)
• Rated motor current (recommended value, dependent on the circuit type
and the power supply)
• Ambient conditions: ambient temperature, control cabinet installation
with IP20 degree of protection or direct local installation with IP66
degree of protection.
Example based on figure 12
• Mains voltage: 3~ 400 V, 50 Hz
• Star-connected circuit (400 V)
• Rated operational current: 1.9 A (400 V)
Control panel installation → IP20 degree of protection
•
• Ambient air temperature: max. 50 °C without output reduction, IP20
￫ Variable frequency drive that should be selected: DC1-342D2FN-A20CE1
• DC1-34...: 3-phase main terminal, rated operating voltage: 400 V
• DC1-...2D2...: 2.2 A – The variable frequency drive's rated operational
current (output current) guarantees that the motor will be supplied with
the required rated operational current (1.9 A).
