5 General Specications
5.1 Mains Supply
Mains supply (L1-1, L2-1, L3-1, L1-2, L2-2, L3-2)
Supply voltage 380–500 V ±10%
Supply voltage 525–690 V ±10%
Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the DC-link voltage drops below the
minimum stop level, which corresponds typically to 15% below the lowest rated supply voltage. Power-up and full torque cannot
be expected at mains voltage lower than 10% below the lowest rated supply voltage.
Supply frequency 50/60 Hz ±5%
Maximum imbalance temporary between mains 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 L1-1, L2-1, L3-1, L1-2, L2-2, L3-2 (power-ups) Maximum 1 time/2 minutes
Environment according to EN 60664-1 Overvoltage category III/pollution degree 2
The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 500/600/690 V
maximum.
5.2 Motor Output and Motor Data
Motor output (U, V, W)
Output voltage 0–100% of supply voltage
Output frequency 0–590 Hz
Switching on output Unlimited
Ramp times 0.001–3600 s
Torque characteristics
Starting torque (constant torque) Maximum 150% for 60 s
1)
once in 10 minutes
Starting/overload torque (variable torque) Maximum 110% up to 0.5 s
1)
once in 10 minutes
Torque rise time in FLUX (for 5 kHz fsw) 1 ms
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 rule, the torque step from 0 to reference is 4–5 x torque
rise time.
5.3 Ambient Conditions
Surroundings
Enclosure IP21/Type 1, IP54/Type 12
Vibration test 0.7 g
Maximum relative humidity 5–95% (IEC 721-3-3; Class 3K3 (non-condensing)) during operation
Aggressive environment (IEC 60068-2-43 Class H
