WEM AC DRIVES CHV190 SERIES FOR CRANES & MINE WINDERS
3 phase 380V/415V/440V/460V/480V/525V±15% 4kW~560kW
Internal contracting brake control and monitor function.
Separated power supply control for control circuit and power circuit. better for faulty detection and maintenance;
Speed increasing function for light load or without load can realize faster speed for sky-hook to improve the efficiency
Master-slave function for speed synchronization can realize speed equilibrium to keep two crane in the same steps.
Master-slave function for power equilibrium to make two motors balance to lift one load through one reduction gear box
Flexible multi-control mode: manual, remote control, potentiometer control, grader remote control, grader manual control, communication.
The second motor control and switch function can decrease the system cost
Support PROFIBUS-DP and MODBUS
Rope slack detection function.
LCD parameters copy and download function to reserve setting.
Speed monitor, Fast stop and overspeed protection
Pre-excitation, starting torque compensation
Better close-loop vector control,200% Mn at 0HZ
Sensorless vector control technology achieve 0.5% control precise.
Support dynamic braking and regenerative braking
Plenty of external ports and strong protection.
