Less current harmonics in the Grid side. Base waveform power factor is close to 1(full load)
Excellent close loop vector control, Zero speed 200% Mn..
Three kinds control mode: sensorless vector control, vector control with PG, V/F control.
The same structure of rectifier and inverter unit, Simplify the system., easy to maintenance.
Sine wave regenerative braking unit, save the energy, protect environment;
Same structure for power unit of rectifier and converter;
Separate control for rectifier and converter;
Special function for lifting application: Logic control when power on, brake control, pre-excitation, overspeed protection, compensation of starting torque and so on;
Support PROFIBUS-DP and MODBUS;
Master-slave function can realize the power equilibrium and speed synchronization;
The second motor control and switch function can decrease the system cost;
Different external port can be used on different application.
Double protection of system and unit module, sequential control when power on, gate control and automatically save before faulty.
Typical application:
STS (SHIP-TO-SHORE CRANE), RMG, Gantry crane, loading machine, unloading machine, dumper;
Large Big tonnage crane-bridge and gate (greater tanr 40 tons );
Crane for mine, conveyer;
Rolling mill using multi-motors, hoists and for blast furnace;
Centrifuge, pouring washer;
Segment drive for paper machine;
Centrifugal casting machine, large punching machine.
