MC-4 Front View

Terminal Interface
Core Electrical Specifications
Power Supply Specifications
Main Circuit: Three-phase AC 342–528V (400V industrial grid standard)
Control Circuit: DC 20–30V direct current supply
Compatible Power: Up to 2kW servo motor
Carrier Frequency: Up to 20kHz, enabling high-speed and high-precision control

Feedback and Motor Interface
Standard absolute encoder (single-turn / multi-turn natively supported)
Three-phase high-power power terminals directly connected to the servo motor
Built-in three-loop closed-loop control: current loop, velocity loop, and position loop

Communication Bus
High-speed fiber-optic bus interface with PacDrive controller
Supports multiple protocols: EtherCAT, CANopen, Modbus-RTU
Distributed rack networking enables remote axis control layout

Structure and Environmental Conditions
Installation: Wall-mounted compact cabinet with integrated high-power heat dissipation fins
Protection Rating: IP20 (for installation inside control cabinet)
Cooling: Natural convection + temperature-controlled auxiliary cooling
Dimensions: Width 100mm × Height 320mm × Depth 400mm; Net weight 3.1kg
Operating Temperature: 0–50°C; Storage: -20–70°C, humidity 5–95% (non-condensing)

Functional Features
Integrated Design: Rectifier power supply, inverter power stage, and servo control board fully integrated into a single unit
No Local Programming Required: Motion programs are entirely issued by the upper-level PacDrive controller; drive only executes axis control
Safety Functions: Multiple protections including overcurrent, overvoltage, undervoltage, overheating, encoder disconnection, and motor stall
I/O Points: Built-in digital input/output terminals for connecting limit switches, enable signals, and fault alarms

Typical Application Scenarios
ELAU primarily targets high-end equipment in the packaging industry; this model is commonly used in:
High-speed vertical/horizontal packaging machines and filling machines
Food and pharmaceutical production lines, labeling and cutting equipment
Precision assembly robots and multi-axis synchronized conveying lines
Printing and papermaking equipment requiring high-precision tension control
