Heidenhain UM 111

The Heidenhain UM 111 is a specialized electronic module that serves as a core component in Heidenhain drive systems, which are widely used in high-precision Computer Numerically Controlled (CNC) machine tools. In technical terms, this product is most often described as a power module (Leistungsmodul), frequency converter (Umrichter), or servo drive.

Its primary function is to control and power a single electric motor. This motor can be either a feed axis motor (responsible for movement along the X, Y, or Z axis) or the machine's main spindle motor. The UM 111 is part of a larger, modular Heidenhain drive system, designed to work in conjunction with supply units (e.g., from the UV or UVR series) and controller units (CC).

Key Features and Characteristics:

• Power Conversion: The UM 111 module converts DC voltage from the drive system's intermediate circuit into a three-phase AC voltage with variable frequency and amplitude. This allows for precise control over the motor's rotational speed and torque.
• Modular Design: Heidenhain drive systems, including the UM series, feature a modular design. This means that several specialized modules are installed side-by-side in the machine's control cabinet—one supply module and a corresponding number of power modules (like the UM 111) for each controlled axis and spindle.
• Product Variants: Several versions of the module exist on the market, differing in their specifications and intended use. For example:
• UM 111B / UM 111BD: These versions may...
