Control Capabilities
This mainboard provides comprehensive control over elevator start, operation, stop, acceleration and deceleration processes. Utilizing closed-loop vector control algorithms, it delivers exceptional performance with speed control accuracy of ±0.01m/s and acceleration control accuracy of ±0.05m/s².
- Supports multi-speed operation (up to 16 speeds)
- Suitable for elevator running speed range of 0.5-4.0m/s
- Ensures smooth start-stop transitions and comfortable operation
Input/Output Configuration
The board integrates extensive I/O capabilities for comprehensive elevator monitoring and control:
- 32 digital inputs (DI) for safety circuits and sensor data
- 16 digital outputs (DO) for control commands
- 8 analog inputs (AI) for precision measurements
- 4 analog outputs (AO) for fine-tuned control signals
Real-time data collection includes safety circuit status, door lock circuits, inspection signals, weighing data, and position information. Processed data is transmitted to drive boards via CAN bus for precise elevator control.
