Siemens Simodrive 611 6SN1118-1NK01-0AA1 Control Units

Description

The Siemens 6SN1118-1NK01-0AA1 is a SIMODRIVE 611 U high-resolution (HR) 2-axis control-loop block designed for resolver speed, torque setpoint control, and positioning tasks. Engineered for precision drive applications, this control unit is expandable with optional feature cards to meet specialized automation requirements. Built with physical dimensions of 35.60 x 5.10 x 17.80 cm and a weight of 0.60 kg, it integrates directly into Simodrive 611 drive racks. Although classified under a phase-out product lifecycle with a designated successor model (6SN1118-1NK01-0AA2 and predecessor 6SN1118-1NK01-0AA0), it remains a critical component for maintaining and supporting legacy multi-axis machine tool and automation systems.

Installation Guidelines

• Ensure all power sources and DC bus supplies to the drive rack are completely switched off before inserting or removing the control block.
• Align the module carefully with the designated slot guides on the Simodrive 611 rack and push it securely into place.
• Connect resolver feedback cables from the motors to the appropriate terminal connections, ensuring proper shielding to prevent signal noise.
• Route feedback and control signal wiring away from high-voltage motor power leads.
• Verify parameter settings and hardware configuration jumpers prior to system energization.
