2,2 – 90 kW
Features |
Applications |
- Electronic DC injection brake with a short delay time can be integrated in controller
- Compact unit easily retrofitted
- Shutdown on detection of phase failure during ramp up
- Controller inhibited when phase sequence is incorrect(E2, E4)
- Version for operation with two phase sequences forreversing drives available (E22, E42)
- Auxiliary module (OPTION I1) allows:
- Soft start with current limit
- Switch-on torque pulse
- Monitoring of power with overload trip
- Improvement of power factor at low load
|
- Machines with gearbox, belt or chain drives
- Drives using pole-change motors
- Conveyor belts (also high speed and high load transportation systems)
- Machines with high moments of inertia e.g. mills, compactors, centrifuges
- Grinding machines and circular saws
- Packing equipment
- Fans and compressors
- Pumps, in particular to reduce hydraulic shock waves
