WEM AC DRIVES CHV190 SERIES FOR CRANES & MINE WINDERS






Product Description:

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.
Typical application:
 Crane for Seaport, metallurgy, machinery, architecture, chemical, transportation, power supply;
 Bridge crane, machine of railway and road construction;
 Crane and Mine Hoist Winder application
