Detailed Product Description

Typical application

STS (SHIP-TO-SHORE CRANE), RMG, gantry crane, lading machine, unloading machine, dumper, big tonnage crane-bridge and gate, crane for mine, conveyer, rolling mill of multi-motors, hoister for blast furnace, centrifuge, pouring washer,segment drive for paper machine, centrifugal casting machine, large punch machine

Features

1.Less current harmonics in the grid side, fundamental waveform power factor is close to 1 (full load)

2.Excellent close loop vector control, zero speed 200% Mn

3.Three kinds control mode: sensorless vector control, vector control with PG, V/F control

4.Sine wave regenerative braking unit to save the energy and protect environment

5.Same structure for power unit to simplify the system and make it easy to maintenance

6.Special function for lifting application: Logic control when power on, brake control, pre-excitation, overspeed protection, compensation of starting torque and so on

7.Support PROFIBUS-DP and MODBUS

8.Master-slave function can realize the power equilibrium and speed synchronization

9.The second motor control and switch function can decrease the system cost

10.Different external port can be used on different application

11.Double protection of system and unit, sequential control when power on, gate control and automatically save before faulty
