6.2 General Specifications
6.2.1 Mains Supply
Mains supply
Supply Terminals (6-Pulse) L1, L2, L3
Supply voltage 200-240 V ±10%
Supply voltage FC 301: 380-480 V/FC 302: 380-500 V ±10%
Supply voltage FC 302: 525-600 V ±10%
Supply voltage FC 302: 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 intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the frequency converter'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) ≤ 7.5 kW maximum 2 times/min.
Switching on input supply L1, L2, L3 (power-ups) 11-75 kW maximum 1 time/min.
Switching on input supply L1, L2, L3 (power-ups) ≥ 90 kW maximum 1 time/2 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.
6.2.2
Motor Output and Motor Data
Motor output (U, V, W)
Output voltage 0-100% of supply voltage
Output frequency 0-590 Hz
3)
Output frequency in Flux Mode 0-300 Hz
Switching on output Unlimited
Ramp times 0.01-3600 s
Torque characteristics
Starting torque (constant torque) maximum 160% for 60 s
1)
once in 10 min.
Starting/overload torque (variable torque) maximum 110% up to 0.5 s
1)
once in 10 min.
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 general rule, the torque step from 0 to reference is 4-5 x
torque rise time.
3) Special customer versions with output frequency 0-1000 Hz are available.
