Specifications

6.3 Mains Supply

Mains supply (L1, L2, L3)
Supply voltage
Mains voltage low/mains dropout:
•
During low mains voltage or a mains dropout, the drive continues until the DC-link voltage drops below the minimum
stop level. This level typically corresponds to 15% below the lowest rated supply voltage of the drive. Power-up and full
torque cannot be expected at mains voltage lower than 10% below the lowest rated supply voltage of the drive.
Supply frequency
Maximum imbalance temporary between mains phases
True power factor (λ)
Displacement power factor (COSφ)
Switching on the input supply L1, L2, L3 (power-ups)
Environment according to EN 60664-1 and IEC 61800-5-1
The unit is suitable for use on a circuit capable of delivering not more than:
•
100000 RMS symmetrical Amperes, 480 V maximum, with fuses used as branch circuit protection.
•
See Table 6.7 and Table 6.8 when using circuit breakers as branch circuit protection.

6.4 Protection and Features

Protection and features
•
Electronic motor thermal protection against overload.
•
Temperature monitoring of the heat sink ensures that the drive trips when the temperature reaches 90 °C (194 °F)
±5 °C (41 °F). An overload temperature cannot be reset until the temperature of the heat sink is below 70 °C
(158 °F) ±5 °C (41 °F). However, these temperatures may vary for different power sizes, enclosures, and so on. The
drive autoderating function ensures that the heat sink temperature does not reach 90 °C (194 °F).
•
The drive motor terminals U, V, and W are protected against ground faults at power-up and start of the motor.
•
When a motor phase is missing, the drive trips and issues an alarm.
•
When a mains phase is missing, the drive trips or issues a warning (depending on the load).
•
Monitoring of the DC-link voltage ensures that the drive trips when the DC-link voltage is too low or too high.
•
All control terminals and relay terminals 01–03/04–06 comply with PELV (protective extra low voltage). However,
this compliance does not apply to grounded delta leg above 300 V.
