Multi-Axis Sway Control – Siemens SIMOCRANE
Overview
A practical application example of multi-axis load sway control using Siemens SIMOCRANE Drive-Based Control with SINAMICS S120 and STEP 7. This solution is used in crane systems to reduce load oscillation and improve positioning precision.
Application Objective
This application aims to enable precise and stable crane motion by minimising load sway across multiple axes (hoist, trolley, gantry), in both manual and automatic modes.
Key Features
– Multi-axis coordination for crane motion
– Load sway suppression for safety and stability
– Manual and positioning control modes
– Integration between PLC and drives
System Components
– PLC: SIMATIC S7 (STEP 7)
– Drive System: SINAMICS S120 with SIMOCRANE Drive-Based Sway Control
– Field setup: Hoist, Trolley, and Gantry axes
How It Works
1. The system reads motion and position feedback from all relevant axes.
2. Sway control algorithms process motion commands.
3. The drive system adjusts positioning in real-time to reduce load swing.
4. Manual or automatic positioning mode is executed as configured.
Typical Use Cases
– Overhead cranes
– Gantry cranes
– Port container cranes
– Heavy lifting and material handling systems
Benefits
– Enhanced load stability
– Improved positional accuracy
– Increased operational safety
– Better motion smoothness
– Reduced operator workload
Required Software
– Siemens STEP 7
– SINAMICS configuration tools
