Influences on positioning accuracy:
The positioning accuracy is determined by the hydraulic and mechanical conditions. The right
choice of valve is therefore a decisive factor. In addition, two mutually contradictory requirements
(short position time and high accuracy) must be considered when designing the system.
The electronic limitations lie mainly in the resolution of the analogue signals, although with our
modules a resolution of < 0.01% only needs to be considered with long positions. In addition, the
linearity of the individual signal points (PLC, sensor and control module) must be considered. The
worst-case scenario is that a system-specific absolute fault occurs.
The repeat accuracy is, however, not affected by this.
