Lenze C30GAC00000F3G0XXX-02S3C300000 Motion Controller – C300 Series

Lenze C30GAC00000F3G0XXX-02S3C300000 — Multi-Axis Motion Controller in the C300 Platform Architecture

The Lenze C30GAC00000F3G0XXX-02S3C300000 is a configurable multi-axis motion controller belonging to the Lenze C300 platform — a modular, scalable control architecture designed for deterministic real-time motion sequencing in industrial drive systems. Within a control loop, this unit occupies the role of the central motion coordinator: it receives setpoint trajectories from the supervisory PLC or HMI layer, executes interpolation and axis synchronization algorithms internally, and transmits torque/velocity references to downstream servo drives via a synchronous fieldbus cycle. The C300 controller’s internal processing pipeline is built around a dual-core ARM Cortex-A architecture with a dedicated real-time co-processor, enabling cycle times as low as 250 µs for position-controlled axes without offloading computation to an external master.

The SKU suffix structure — C30G / AC00000 / F3G0 / XXX / 02S3 / C300000 — encodes the hardware configuration: communication interface selection (EtherCAT master, CANopen, or PROFIBUS DP), safety option level (STO/SS1/SLS up to SIL 2 / PLd), firmware variant, and I/O expansion slot population. The XXX field represents a configurable option block; buyers must confirm the exact variant code against their bill of materials prior to procurement to ensure fieldbus and safety function compatibility.

Technical Parameters

Hardware Logical Analysis

Backplane Bus Architecture & Axis Synchronization: The C300 controller communicates with downstream Lenze i550/i650 inverter drives and ECS servo drives via a synchronous EtherCAT master stack embedded directly in the controller firmware. The EtherCAT distributed clock (DC) mechanism locks all slave devices to a common reference time with a jitter of < 1 µs across the network, which is the physical basis for the deterministic multi-axis synchronization the platform advertises. The controller’s real-time co-processor handles the EtherCAT frame scheduling independently of the application CPU, preventing application-layer latency spikes from propagating into the motion cycle.

EMC Design & Galvanic Isolation: The 24 V DC logic supply rail is galvanically isolated from the fieldbus transceivers and the digital I/O interface via DC/DC converters and optocoupler barriers rated at 500 V AC isolation voltage. This isolation topology prevents ground-loop currents — common in large panel installations with multiple drive cabinets — from coupling noise into the controller’s signal processing chain. The PCB layout follows IEC 61800-3 Category C2 guidelines, with separate ground planes for analog reference, digital logic, and chassis earth, joined at a single star point.

Functional Safety Subsystem: The integrated safety processor operates on a separate execution domain from the motion application CPU. Safety function requests (STO, SS1, SLS) are processed through a dual-channel hardware path with cross-comparison logic, conforming to the diagnostic coverage requirements of IEC 62061 SIL 2. The safety subsystem maintains its own watchdog timer and will de-energize the STO output independently of the application CPU state — meaning a software fault in the motion application does not compromise the safety shutdown path.

Memory Architecture: The controller provides non-volatile FLASH storage for the user application program and retain variables, with a battery-backed SRAM region for fast-access retain data that survives power cycles without FLASH write latency. This architecture is significant for applications requiring sub-second restart after power interruption, such as conveyor synchronization systems where axis position data must be preserved across unplanned shutdowns.

System Integration Benefits

• Deterministic EtherCAT Cycle: The embedded EtherCAT master with distributed clock synchronization delivers axis-to-axis jitter below 1 µs, enabling electronic gearing and cam profiling without mechanical coupling hardware.
• Unified Engineering Environment: Lenze EASY Engineer software provides a single workspace for drive parameterization, IEC 61131-3 PLC programming, motion function block configuration, and safety validation — reducing commissioning time compared to multi-tool workflows.
• Scalable Axis Count: The EtherCAT topology supports up to 32 synchronized axes from a single C300 controller, allowing machine builders to scale from 2-axis test rigs to 32-axis production lines without changing the control architecture.
• Integrated Diagnostic Transparency: The controller exposes axis-level diagnostic data — following error, actual torque, thermal load, and fieldbus cycle overrun counters — via the EtherCAT CoE object dictionary, accessible from any standard EtherCAT master diagnostic tool without proprietary software.
• SIL 2 Safety Without External Safety PLC: Integrated STO/SS1/SLS functions eliminate the need for a separate safety relay module or safety PLC for basic machine guarding, reducing panel BOM cost and wiring complexity.
• IEC 61131-3 Portability: Application programs written in Structured Text or Function Block Diagram are portable across Lenze C300 hardware variants and compatible with third-party IEC 61131-3 runtimes, protecting software investment across machine generations.
• Multi-Protocol Flexibility: Support for EtherCAT, CANopen, and PROFIBUS DP within the same hardware platform allows the controller to integrate into existing plant networks without gateway hardware, reducing network latency and single-point-of-failure risk.
• Retain Variable Architecture: Battery-backed SRAM for retain variables enables sub-second warm restart after power interruption, preserving axis position data and production counters without requiring a full home cycle after every power event.
• Thermal Derating Monitoring: The controller continuously monitors its internal thermal state and provides a pre-warning output before reaching the thermal shutdown threshold, allowing the supervisory system to execute a controlled stop rather than an emergency trip.
• Firmware Update via USB/SD: Field firmware updates are performed via USB or SD card without requiring a laptop or engineering software connection, reducing service time in remote installations.
