LMC058LF42 | Schneider Electric 42 I/O Motion Controller

What Makes the LMC058LF42 Motion Controller Essential for Complex Automation?

How can a single controller manage up to 8 synchronized axes while maintaining deterministic cycle times? The Schneider Electric LMC058LF42, part of the Modicon LMC058 series, answers this with a dual-core ARM Cortex-A8 processor and dedicated motion protocols. It executes Boolean instructions in 22 ns, ensuring precise real-time control. With 42 I/O points and support for up to 7 TM5 expansion modules, this controller scales to meet demanding applications.

LMC058LF42 Technical Specifications and Motion Capabilities

The LMC058LF42 integrates 26 digital inputs (10 fast, 12 regular, 4 configurable) and 16 digital outputs (12 regular, 4 fast). It lacks analog I/O, so analog signals require external modules. For motion, it supports up to 8 synchronized axes via CANmotion master, achieving a 2 ms cycle for 4 axes. An incremental encoder input (SUB-D15, 5V differential RS-422) provides precise position feedback. Communication options include Ethernet (Modbus TCP/IP), serial (Modbus RTU/ASCII), and dual CAN ports (CANopen master).

Key Electrical and Environmental Parameters

• Supply voltage: 24 V DC (20.4...28.8 V)
• Power consumption: 13.03 W
• Bus current: 0.28 A @ 24V DC (main supply); 0.04 A (embedded expert modules)
• Operating temperature: 0...+55 °C
• Protection rating: IP20
• Dimensions (H×W×D): 175 × 99 × 85 mm
• Weight: 0.55 kg

Applications and Integration of the LMC058LF42

This controller excels in packaging, material handling, and assembly systems where synchronized motion is critical. For example, in a rotary indexing table, the LMC058LF42 coordinates multiple servo axes with precise electronic camming. Its CANmotion protocol ensures deterministic communication, reducing jitter. Integration with supervisory systems is straightforward via Modbus TCP/IP over Ethernet. However, when connecting to other fieldbus networks, an external gateway may be required. The built-in USB ports simplify programming and data logging.

Installation and Maintenance Guidelines

Mount the LMC058LF42 on a symmetrical DIN rail inside an IP20 enclosure. Ensure proper ventilation to maintain operating temperature within 0...+55 °C. For wiring, follow Schneider Electric's guidelines for 24 V DC supply and communication cables. Periodic inspection of connections and battery (3 V CR2477M lithium for RTC) is recommended. Since the product is discontinued (end of sale: 2026-06-30; service end: 2031-06-30), verify lifecycle status with AutoDCSTech before ordering. Replacement options include Modicon M262.
