Key Features and Advantages

The **CLM01.4-N-N-2-B-FW/CLM** enables precise motion control with sub-micron positioning accuracy through its adaptive current loop tuning. Its dual-channel safety inputs (STO/SBC) meet SIL 3/PLe requirements for collaborative robotics. The integrated energy recovery circuit reduces power consumption by up to 25% during regenerative braking cycles.

Real-time compensation for mechanical resonance and backlash ensures smooth operation at speeds up to 5,000 rpm. The modular design allows firmware updates via USB without disassembly. For harsh environments, the aluminum housing with conformal coating resists oil mist and metal particulates in CNC machining centers.
