Control logic precedes action.
Risks in stage machinery arise from multiple devices operating simultaneously. The control system's role is not to accelerate movements, but to ensure every action occurs within clear logic and defined boundaries.
ARCHITECTURE / LEVEL 1–4
Schedule a technical discussionA signal axis spans four layers.
Console and Scene Orchestration
Operation Layer
Scenario orchestration, single-node jog, and status overview. Permissions are role-based; critical actions require double confirmation.
Bus Communication and Command Verification
Logic Layer
Receive and validate interlock conditions, decompose the scenario into executable action sequences, and reject execution with logging on exceptions.
Drive Unit and Closed-Loop Execution
Execution Layer
The VFD, hydraulic station, and brake operate per controller commands with adjustable speed curves to ensure smooth start-stop transitions.
Sensor Feedback and Limit
Feedback Layer
Encoders, limit switches, slack rope detection, and anti-shear monitoring continuously transmit position and status data to form a closed-loop system.

Interface Overview
The number of interfaces and devices shown is for illustration only; the actual configuration follows project equipment specifications and operational workflows.
Cabinet
The control cabinet is organized by circuit zones, with power and signal wiring separated. Internal labels match drawing numbers for easy troubleshooting.
- The control interface and linkage logic are configured based on the actual device setup for each project. The status views shown in the page are illustrative only and do not represent the final delivered interface.
- Fire safety and performance security requirements are subject to local regulations and acceptance guidelines at the project location.
Stop risks before they happen.
Emergency stop circuit
Emergency stop buttons are installed at the control console and on both sides of the stage, wired in series within the hardware circuit to cut off power output upon activation.
Travel and Limits
Hierarchical configuration of upper/lower limits, deceleration zones, and mechanical stops. The system slows down before stopping when limits are exceeded to prevent structural impact.
Interlock Logic
Interlock between scissor lift and vehicle platform, and between boom and deck: commands are invalid if conditions are not met.
Permission Levels
Restrict operations based on role: Administrator, Operator, or Maintenance. Speed is limited in Maintenance mode.
Fire life-safety and performance management requirements are governed by local regulations, approved fire design documents, and acceptance findings. This page does not assert unverified certifications or standard numbers.

The control system configuration must be determined alongside the device type. First, classify the devices, then define the interlock logic.
