Elevator control board.
The elevator control panel is constructed from 1.5–2.5 mm thick galvanized steel or stainless steel metal sheets. Standard dimensions range from 800x600x200 mm to 1200x800x300 mm with IP54 protection rating for dusty and humid environments. The control system utilizes PLC or microprocessor-based technology with 32-bit processors, 1 GB memory, and 1000 command/sec processing capacity. The panel incorporates a Variable Frequency Drive VFD with 5.5–60 kW power range and 0.01% speed control accuracy. Communication modules include industrial Ethernet Profinet/EtherCAT, CANopen protocol, and RS-485 connectivity for Building Management System BMS integration. All equipment is certified per IEC 60364, EN 81-20, and UL 508A standards.
Internal structure comprises power supply section 380-480VAC three-phase input, control unit, and motor drive section. The system includes circuit breakers 10–200A range, overload relays, and surge protection devices. A touchscreen HMI display 7–15 inches, 1280x800 pixels with 100,000 event logging capability is installed. Integrated sensors include current monitoring CT sensors ±0.5% accuracy, motor temperature monitoring, and encoders with 1024 pulses/revolution resolution. The system features automatic self-diagnostics with 200 error codes and
