8.2 General Specifications
Mains supply (L1, L2, L3)
Supply voltage 380-480 V ±10%
Mains voltage low / mains drop-out:
During low mains voltage
or a mains drop-out, the frequency converter 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 frequency converter's lowest rated supply voltage.
Supply frequency 50/60 Hz ± 5%
Max. 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, L2, L3 (power-ups) maximum 2 times/min.
The unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical Amperes, 480 V maximum.
Motor output (U, V, W):
Output voltage 0-100% of supply voltage
Output frequency 0-1000 Hz
Output frequency in Flux Mode 0-300 Hz
Switching on output Unlimited
Ramp times 0.01-3600 s

Protection and Features
•
Electronic thermal motor protection
against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a
predefined level.
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
•
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.
•
The frequency converter constantly checks for critical levels of internal temperature, load current, high voltage on
the intermediate circuit and low motor speeds. As a response to a critical level, the frequency converter can adjust
the switching frequency and/ or change the switching pattern in order to ensure the performance of the drive.
