2 The typical power loss is at normal load conditions and expected to be within ±15% (tolerance relates to variety in voltage and cable conditions).
Values are based on a typical motor efficiency. Lower efficiency motors also add to the power loss in the drive and conversely. If the switching fre-
quency is raised from nominal, the power losses may rise significantly. LCP and typical control card power consumptions are included. Further op-
tions 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). Although measurements are made with state-of-the-art equipment, some measurement inaccuracy must be allowed for (±5%).

Environment according to EN60664-1
Mains voltage low/mains dropout: During low mains voltage or a mains dropout, the drive continues until the DC-link voltage drops below the
1
minimum stop level, which corresponds typically to 15% below the drive's lowest rated supply voltage. Power-up and full torque cannot be expec-
ted at mains voltage lower than 10% below the drive's lowest rated supply voltage.
The unit is suitable for use on a circuit capable of delivering not more than 100000 RMS symmetrical Amperes, 240/500/600/690 V maximum,

depending upon drive power and voltage rating.
If type code position 23 = 6: UL 61800-5-1, the supply voltage is 3x115Y/200–139Y/240 V.

If type code position 23 = 6: UL 61800-5-1, the supply voltage is 3x220Y/380–277Y/480 V.
