The 6RB2100-0NA21 is a SIMODRIVE 210 DC-FDD (Feed Drive) control unit, specialized for the analog management of up to three motion axes. Designed for legacy industrial automation applications, this APCB (Assembled Printed Circuit Board) control unit provides precise motion coordination and drive regulation. It serves as the primary intelligence for multi-axis feed drive systems, translating analog signals into controlled mechanical movement for high-precision machinery.

Features

  • Multi-Axis Management: Controls up to 3 independent axes, facilitating synchronized motion in complex machinery.
  • Analog Interface: Utilizes high-reliability analog signal processing for drive regulation.
  • SIMODRIVE 210 Compatibility: Specifically engineered for the legacy SIMODRIVE 210 ecosystem, ensuring direct integration with existing DC feed drive configurations.
  • Reliable Construction: Designed for stable performance in demanding industrial production environments.

Applications

  • Multi-axis machine tools and coordinate measuring machines.
  • Legacy CNC systems requiring analog feed drive regulation.
  • Industrial automation setups utilizing DC-FDD motor technology.
  • Maintenance and sustainment of established multi-axis manufacturing lines.

Installation Guidelines

  • Cabinet Installation: Ensure the unit is mounted in a dust-free, climate-controlled cabinet to prevent environmental contamination of the APCB components.
  • Signal Integrity: Given the analog nature of this control unit, keep signal cables shielded and routed strictly away from high-current power cables to prevent electromagnetic interference (EMI).
  • Grounding: Proper grounding of the unit is essential for stable analog performance. Ensure all shielding is terminated at a common ground point as specified in the SIMODRIVE 210 documentation.
  • System Maintenance: As this unit is in the "Phase-Out" stage, verify that your existing system power supplies and feedback loops are in good working order, as aging peripheral components are common points of failure in older SIMODRIVE installations.

FAQ

What is the primary function of the 6RB2100-0NA21?
It is an analog control unit for the SIMODRIVE 210 DC-FDD system, capable of managing up to 3 separate axes of motion.

Does this module use digital or analog control?
This module is designed for analog control signal management.
