General Technical Data - Danfoss VLT FC 322 Instruction Manual

Specifications VLT® Automation VT Drive FC 322 D-Frame Instruction Manual
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within ±15% (tolerance relates to
variety in voltage and cable conditions).
5) Field wiring terminals on FC 322 N132, N160 and N315 models are not intended to receive conductors one size
larger.
Values are based on a typical motor efficiency (eff2/eff3 border line). Motors with lower efficiency will add to the
power loss in the frequency converter and those with higher efficiency will decrease it.
The losses are based on the default switching frequency. The losses increase significantly at higher switching
frequencies. LCP and typical control card power consumptions are included. Further options and customer load
may add up to 30 W to the losses. (Though typically, only 4 W extra for a fully loaded control card, or options for
slot A or slot B, each).

10.2 General Technical Data

Mains supply (L1, L2, L3)
Supply voltage
Mains voltage low / mains voltage drop-out:
During low mains voltage or a mains drop-out, the FC continues until the intermediate circuit voltage drops below the minimum
stop level, which corresponds typically to 15% below the FC's lowest rated supply voltage. Power-up and full torque cannot be
expected at mains voltage lower than 10% below the FC's lowest rated supply voltage.
