8.2 Line Power Supply

Line power supply

Supply Terminals L1, L2, L3

Supply voltage 200–240 V ±10%

Supply voltage 380–480 V/525–600 V ±10%

Supply voltage 525–690 V ±10%

AC line voltage low/line drop-out:

During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage

drops below the minimum stop level, which corresponds typically to 15% below the adjustable frequency drive's lowest rated

supply voltage. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the adjustable frequency

drive's lowest rated supply voltage.

Supply frequency 50/60 Hz ±5%

Max. temporary imbalance between line phases 3.0% of rated supply voltage

True Power Factor (λ) ≥ 0.9 nominal at rated load

Displacement Power Factor (cos ϕ) near unity (> 0.98)

Switching on input supply L1, L2, L3 (power-ups) ≤ 10 hp [7.5 kW] maximum 2 times/min.

Switching on input supply L1, L2, L3 (power-ups) 11–90 kW maximum 1 time/min.

Environment according to EN60664-1 Overvoltage category III/pollution degree 2

The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes,

240/500/600/690 V maximum.

8.3 Motor Output and Motor Data

Motor output (U, V, W)

Output voltage 0–100% of supply voltage

Output frequency (1.1–90 kW) 0–590

Switching on output Unlimited

Ramp times 1–3600 s

1) From software version 3.92, the output frequency of the adjustable frequency drive is limited to 590 Hz. Contact local Danfoss

partner for further information.

Torque characteristics

Starting torque (Constant torque) maximum 110% for 60 s

Starting torque maximum 135% up to 0.5 s

Overload torque (Constant torque) maximum 110% for 60 s

Starting torque (Variable torque) maximum 110% for 60 s

Overload torque (Variable torque) maximum 110% for 60 s

Torque rise time in VVC

(independent of fsw) 10 ms

1) Percentage relates to the nominal torque.

2) The torque response time depends on application and load but as a general rule, the torque step from 0 to reference is 4–5 x

torque rise time.
