Standard I/O • Digital Inputs: 4 (including 1 high-speed input) • Digital Outputs: 2 (1 relay, 1 transistor) • Analog Inputs: 2 (1 voltage 0-10V, 1 configurable 0-10V/0-20mA) • Analog Output: 1 (0-20mA) Integrated Communication RS-485 serial port (Modbus) as standard. Note: This M3C version does not include built-in Ethernet. Ethernet requires a separate communication card or a different model variant (e.g., N4). Communication Slot 1 slot for optional communication cards (e.g., PROFINET, EtherNet/IP, CANopen) or I/O expansion cards. Keypad / Display Integrated Graphic Display Keypad supplied as standard (as indicated by M3). Enclosure IP20 / UL Type 1 (Panel-mounted, requires installation in a suitable enclosure). Protection Features Motor overload, short-circuit, ground fault, overvoltage, undervoltage, phase loss, overheating, motor preheating. Braking 100% braking torque capability. For frequent braking, an optional braking resistor is required. Ambient Temperature -10°C to +50°C (with derating above 40°C). Up to +60°C with significant derating. Storage Temperature -25°C to +70°C Relative Humidity 5% to 95% (non-condensing) Pollution Degree 2 Standards & Certifications CE, cULus, RoHS, compliant with IEC 61800-5-1, IEC 61800-3. Configuration Software SoMove (Free software for commissioning and parameter management). Can also be fully configured via the integrated keypad. Typical Applications Small conveyors, packaging machinery, rotary tables, fans, pumps, and other industrial machines requiring precise speed/torque control from a single-phase power supply.
