VEIKONG CH530 Anti-Sway Crane AC Drive 0.75-710kW Vector Control Inverter for

Product Specification

1.Product Introduction

The VEIKONG CH530 Series is a specialized AC drive for crane travelling, hoisting, and slewing mechanisms. It provides precise speed and torque control for bridge cranes, gantry cranes, tower cranes, overhead cranes, port cranes, electric hoists, and industrial winches.

The drive integrates anti-sway control, professional brake control, automatic load-based speed adjustment, zero-servo protection, and dedicated crane application macros. These functions help reduce suspended-load movement, improve positioning efficiency, and support smooth operation during acceleration, deceleration, stopping, and direction changes.

With three-phase AC 380V–480V input and power ratings from 0.75kW to 710kW, the CH530 can be applied to small lifting devices as well as large industrial crane systems.

3.Integrated Anti-Sway Control

A suspended load may swing when the crane trolley or bridge accelerates, decelerates, stops, or changes direction. Excessive load swing can make accurate positioning difficult, extend the material-handling cycle, and require repeated operator adjustment.

The CH530 integrates an anti-sway algorithm for crane travelling mechanisms. By optimizing the speed-change process, the drive helps reduce suspended-load oscillation during trolley and bridge movement.

Reduced load swing can provide several operational benefits:

• Faster load positioning
• Fewer forward and reverse corrections
• Smoother crane travelling
• Reduced operator workload
• Improved material-handling efficiency
• Less mechanical shock during speed changes

4.Precise Control for Trolley and Bridge Travel

Crane travelling mechanisms require smooth starting and stopping to prevent wheel impact, structural vibration, and excessive load movement.

The CH530 supports linear and S-curve acceleration and deceleration. Four groups of acceleration and deceleration times can be set for different movements and operating stages.

Smooth speed control helps reduce stress on crane wheels, rails, couplings, gearboxes, and supporting structures. It also improves travelling stability when the crane operates at different speeds.

5.Dedicated Hoisting Control

In addition to travelling applications, the CH530 provides the torque and brake-control functions required for lifting and lowering.

The drive establishes motor torque before releasing the mechanical brake, helping reduce load slipping during startup. Adjustable brake timing allows the drive and mechanical brake to work in the correct sequence.

Under closed-loop vector control, the drive can provide up to 150% starting torque at 0Hz, supporting stable heavy-load startup and low-speed operation.

6.Load-Based Speed Optimization

The CH530 automatically adjusts the operating speed according to the detected load.

Under light-load conditions, the drive can increase the speed to reduce the lifting or handling cycle. Under heavy-load conditions, it can reduce the speed to maintain reliable control and protect the mechanical system.

This function is useful for cranes that frequently handle loads of different weights. It helps improve efficiency when the load is light while maintaining controlled operation when the load is heavy.

7.Zero-Servo Holding Function

When the crane is stopped, the mechanical brake normally keeps the load or travelling mechanism in position. If the brake does not close correctly or its holding force is insufficient, unexpected motor movement may occur.

The CH530 can detect motor shaft movement and activate the zero-servo function. The drive generates holding torque to help maintain the current position and can issue an alarm to indicate the abnormal condition.

This function provides additional monitoring and holding support for crane systems.

8.Multiple Crane Application Macros

The CH530 includes pre-programmed parameter macros for typical crane mechanisms, reducing the time required for basic parameter configuration.

Available application directions include:

• Hoisting mechanisms
• Trolley travelling mechanisms
• Bridge travelling mechanisms
• Tower crane slewing mechanisms

The selected macro can be further adjusted according to the motor data, equipment structure, control method, mechanical brake, and operating requirements.

9.Flexible Vector Control

The CH530 supports three main motor-control methods:

V/F Control

Suitable for crane mechanisms with basic speed-control requirements.

Sensorless Vector Control

Provides improved speed and torque performance without requiring encoder feedback.

Closed-Loop Vector Control

Uses encoder feedback to provide more accurate speed and torque control. It is suitable for demanding hoisting applications that require high starting torque and stable operation at very low speed.

10.Supported Motor Types

The CH530 supports:

• Asynchronous induction motors
• Permanent magnet synchronous motors
• Crane motors used in different lifting and travelling mechanisms
• Cone motors commonly used with lifting equipment

This compatibility allows the drive to be used in new installations, system upgrades, and replacement projects.

11.Application Areas

Bridge and Overhead Cranes

The CH530 provides anti-sway control, smooth bridge travel, accurate trolley speed regulation, and dedicated brake control for lifting mechanisms.

Gantry Cranes

Smooth acceleration and deceleration help reduce mechanical impact during long-distance bridge travel. The drive can be used for hoisting, trolley travel, and gantry travel mechanisms.

Tower Cranes

The CH530 supports smooth slewing, lifting, and trolley movement. Controlled speed changes help reduce structural impact and suspended-load swing.

Port and Container Cranes

Wide power coverage, vector control, and communication expansion options make the drive suitable for large material-handling systems.

Electric Hoists and Winches

High starting torque, professional brake control, and stable low-speed performance support lifting, lowering, winding, and unwinding operations.

Mining and Metallurgical Cranes

The CH530 provides heavy-load starting performance and flexible braking-system configuration for demanding industrial lifting applications.

12.Product Highlights for Crane Projects

Enhanced Positioning Efficiency

Anti-sway control helps the suspended load stabilize more quickly after travelling.
