Energy chain options include various configurations for horizontal and vertical energy supply. Limit switches options for inductive PNP and NPN limit switches. Central lubrication is available as an option.
- Precision vs. Repeatability: Precision involves systematic target/actual deviations plus 2 sigma (standard deviation). Repeatability is the ability to return to a target position consistently, measured unidirectionally or bidirectionally, with or without the effect of backlash.
- Resolution: The smallest detectable distance by the measuring system, generally less than the achievable step width due to additional factors.
- Rigidity: Resistance to mechanical deformation under static or dynamic loads, indicating static or dynamic rigidity.
- Single-index: Magnetic tapes with incremental and index tracks, providing reference signals when crossed, tailored to customer specifications.
- Step Width: The minimum repeatable distance traversed by a linear drive, influenced by resolution and drive train errors.
- Straightness: Horizontal movement deviation on the X-axis, measured by displacement on the Y-axis.
- Torque: A rotational movement variable, expressed as M = r × F1, measured in Nm.
- Wobble: Angular deviation in rotary tables due to bearing tolerances.
- Coil-independent Dimensions:
- Fa: Constant attraction force between primary and secondary parts.
- Fc: Continuous motor force leading to warming.
- Fp: Briefly generated motor force causing significant heating without cooling.
- Km: Motor constant indicating force to power loss ratio.
- Pv: Heat output leading to temperature increase, calculated using Km.
- Pvp: Peak power loss at peak current (Ip).
- Pc: Power loss at continuous current (Ic).
- T: Permitted coil temperature, influenced by installation, cooling, and operation mode.
- Coil-dependent Dimensions:
- Ic: Current for continuous force generation.
- Ip: Peak current for peak force generation.
- Kf: Coil dimension for force production with current.
- Ku: Coil dimension for armature counter voltage as a function of speed.
- R25: Coil resistance at 25°C, increasing at higher temperatures.

3. Calculation basis3.1 Service life calculation for KK/KF spindle axes3.1.1 Service life calculation The repeated strain of the block and shaft results in signs of fatigue on the surface of the track and ultimately leads to pitting. The service life of a linear axis is defined as the total travel distance covered until pitting occurs on the surface of the track or shaft. The service life can vary greatly even if linear axes are manufactured in the same way and used under the same movement conditions. Therefore, the nominal service life is taken as a reference value for estimating the service...

3.1.2.1 Calculation of the service life of the linear guide Since the load on a block varies greatly, an equivalent load must be included in the calculation of the service life. The equivalent load is defined as the load that causes the same wear on the bearings as the variable load. In this way non-constant operating conditions are taken into consideration. - Combined dynamic equivalent load This formula allows for a simplified calculation of the dynamic equivalent load.
