Soft Limit Controller Systems
Precision Motion Control for Entertainment Rigging Applications
The Motion Laboratories Soft Limit Controller is a scalable, wall-mounted motion control platform designed to provide accurate, repeatable position limiting for fixed-speed electric chain hoists used in entertainment, theatrical, touring, and staging environments.
Built around a PLC-driven control architecture with encoder-based positional feedback, the system allows operators to define, monitor, and recall hoist travel positions with accuracy and operational consistency.
Whether you are configuring a small venue installation or a large multi-hoist production system, the Motion Labs Soft Limit platform can be tailored to your application with flexible channel counts, operator interface options, load monitoring, SCADA integration, and custom engineering support.
Built for Real-World Entertainment Environments
Entertainment motion systems require more than basic up/down control. Productions demand repeatability, visibility, scalability, and operational confidence.
The Motion Labs Soft Limit Controller provides:
Position-based motion limiting
- Encoder feedback integration
- Modular system expansion
- Centralized operator control
- Integrated safety functionality
- Flexible control of architecture
- Support for multiple hoist configurations
The result is a system designed to simplify operation while supporting the complex requirements of modern productions.
Modular & Scalable Architecture
The Soft Limit Controller platform is modular by design and scalable in standard 8-channel increments.
Standard Configurations
- 8 Channels
- 16 Channels
- 24 Channels
- 32 Channels
Custom Systems
Custom engineered systems are available for applications requiring up to 80 channels or specialized control architectures.
This scalable approach allows productions to maintain a consistent operator experience regardless of system size while providing flexibility for future expansion.
Flexible Operator Interfaces
The Motion Labs Touch Screen Operating System (TSOS) provides an intuitive operator experience for configuration, monitoring, and system control.
7.5″ TSOS Interface
Recommendation for:
- Smaller systems
- 8 channels and below
- Compact operator stations
Features:
- Position monitoring
- Configuration access
- Channel status visibility
- Motion control functionality
12″ TSOS Interface
Recommendation for:
- Larger systems
- Grouped hoist management
- Expanded system visualization
Features:
- Increased screen real estate
- Enhanced channel organization
- Improved system visibility
- Simplified large-system operation
Our sales and engineering teams can help determine the best interface configuration for your application and operational workflow.
Integrated Load Monitoring Options
Integrated load monitoring adds another level of operational awareness and system protection.
Using load cells within the control architecture, operators can monitor real-time weight data directly through the TSOS interface.
Optional Load Monitoring Features
- Real-time load visualization
- Overweight shutdown protection
- Underweight shutdown protection
- Operator load awareness
- Integrated safety monitoring
Load monitoring can be configured for applications requiring enhanced visibility during lifting and positioning operations.
TALOS SCADA Integration
For larger or more complex systems, Motion Labs offers TALOS SCADA integration for centralized supervisory monitoring and control.
TALOS allows operators and technical personnel to oversee multiple Motion Labs systems from a unified interface while improving operational visibility across installations or productions.
TALOS Features
- Centralized monitoring
- Multi-controller visibility
- Supervisory control functionality
- Integrated fixed and variable speed system moves
- Enhanced operational awareness
- Running Sequences with hoists from any Motion Lab’s controllers
