Input Signal Processing
The following processing is applied to all input signal channels of the E-727 (channels for internal
sensors of the mechanics and for analog input lines):
 Analog to digital conversion
 Digital processing (filtering and linearization / scaling)
 Allocation of input signal channels to axes via the input matrix to calculate the axis
positions from the input signals

Analog to digital conversion
The results of the analog to digital conversion can be queried with the TAD? command for all
channels.
Digital processing
The digital processing of the input signals comprises the following steps:
 Digital filtering
 Electronics linearization
 Mechanics linearization
