SYSTEM DESCRIPTION
Specifications FR-F 740-01800 to -12120
ቢ
The performance figures at the rated motor capacity are based on a motor voltage of 400 V.
ባ
The overload capacity in % is the ratio of the overload current to the inverter’s rated current in the respectiveoperating mode. For repeated duty cycles allow sufficient time for the inverter and the motor to
cool below the temperature reached at 100% load. The waiting periods can becalculated using the r.m.s. current method (I² ×t), for which knowledge of the duty.
ቤ
The maximum output voltage cannot exceed the power supply voltage. The output voltage can be varied overthe entire power supply voltage range.
ብ
The rated input capacity varies depending on the impedance values on the power supply side of theinverter (including the cables and input reactor).
ቦ
When the load curve with 120% overload capacity is selected the maximum permitted ambient temperature is 40°C.
ቧ
When operating with carrier frequencies ≥2.5 kHz this value is reduced automatically as soon as the frequency inverter exceeds the rated output current shown in parentheses (= 85% load).
ቨ
When the cable bushing for the optional expansion cards is broken out the unit has anIP 00 protection rating.
ቩ
The suffix EC or E1 in the model designation identifies the CE versions of the frequency inverter (for the European Union). The inverter types FR-F740-02160 and above are all delivered in the E1 versionas
standard (PCBs with two coats of protective varnish). The EC version (varnished PCBs) is standard for types FR-F740 00023 through 01800. The otherversion as always available as an option.
