Product Description
The 6SN1118-0DK23-0AA2 is a digital control loop module designed for the Siemens SIMODRIVE 611 system. It provides closed-loop regulation for dual-axis drive configurations. The hardware incorporates a direct measuring interface for Sin/Cos 1 VPP encoders, facilitating high-resolution position and velocity feedback. This eliminates the need for external signal converters, ensuring deterministic communication across the digital drive bus for precision CNC and multi-axis motion control tasks.
Mechanical housing specifications include a 0.53 kg net weight and a required vertical mounting orientation for thermal management. The unit is rated for operation at altitudes up to 1000 meters MSL (Mean Sea Level) without power derating. Operational ambient temperature is limited to 0°C to 40°C, while storage tolerances are rated from -40°C to 70°C. These parameters ensure the stability of the digital logic and internal circuitry in standard industrial cabinet environments.
Safety and regulatory compliance are verified by CE and cULus certifications. The module is designed for non-condensing environments with relative humidity up to 95% to prevent dielectric failure. This control block serves as a standard component for SIMODRIVE digital drive systems, providing the high-speed processing required for continuous-duty cycles in automotive assembly, aerospace tooling, and high-demand manufacturing cells.
Technical Specifications & Frequently Asked Questions
|
AXIAL CONFIGURATION
Q: Does the 0DK23-0AA2 support independent commutation for dual-axis drive trains?
A: Yes. The module is specifically architected for dual-axis regulation within the SIMODRIVE 611 framework. It processes two separate feedback loops simultaneously, allowing a single hardware slot to manage independent velocity and position control for two distinct motors.
|
ENCODER INTERFACE PROTOCOL
Q: What is the specific signal requirement for the direct measuring system?
A: The unit is hard-coded for Sin/Cos 1 VPP analog signals. By utilizing this direct interface, the module performs high-resolution signal acquisition without external interpolation, minimizing loop latency and maintaining deterministic communication across the digital drive bus.
|
|
THERMAL ORIENTATION CONSTRAINTS
Q: Is horizontal mounting permissible in high-density, low-clearance control racks?
A: Negative. Vertical mounting is a mandatory mechanical requirement. This orientation is essential for passive thermal convection. Deviating from vertical installation compromises internal airflow, leading to localized heat pockets that may cause digital logic drift or premature component failure.
|
MSL ALTITUDE LIMITS
Q: At what elevation does power derating become a factor for this control block?
A: The 6SN1118-0DK23-0AA2 maintains its full performance envelope up to 1000 meters MSL (Mean Sea Level). For deployments exceeding this threshold, derating calculations are required due to reduced air density and the subsequent decrease in heat dissipation efficiency.
|
|
DIELECTRIC INTEGRITY & HUMIDITY
Q: How does the module mitigate short-circuit risks in environments reaching 95% relative humidity?
A: The unit is rated for 95% non-condensing humidity. While the PCB is designed for industrial atmospheric tolerance, the control cabinet must maintain a temperature above the dew point. This prevents micro-condensation on the high-density digital traces, which is critical for preventing dielectric failure.
|
COLD-START RECOVERY (STORAGE)
Q: What is the stabilization protocol for a unit stored at the -40°C lower limit?
A: Units stored at -40°C must undergo a thermal soak at room temperature (minimum 4 hours) before power-up. Immediate energization of a "cold" module can cause internal thermal shock and condensation, potentially compromising the internal digital circuitry.
|
|
MECHANICAL VIBRATION STABILITY
Q: Does the 0.53 kg net weight necessitate specialized dampening in CNC tool-head applications?
A: The 0.53 kg mass is optimized for the SIMODRIVE 611 frame. While lightweight, it must be secured with the standard integrated locking screws to ensure gas-tight connectivity to the drive bus, especially in high-vibration aerospace or automotive machining centers.
|
GLOBAL REGULATORY TRACEABILITY
Q: Can this module be deployed in North American and European markets without additional safety certification?
A: Yes. The hardware carries both CE and cULus marks. This dual certification ensures the module meets international safety directives and electromagnetic compatibility (EMC) standards required for industrial environments in both regions.
