 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.
