Modulo activated
When "Modulo" is activated (value = 1), the encoder value is mapped onto a recurring
modulo range. The modulo range is defined by the start value and the length. The start value
corresponds to the "Minimum encoder value" parameter.
The length is calculated using the following formula:
Length = ABS (maximum encoder value - minimum encoder value) +1
Figure 6-10
Encoder module
With the help of the "Encoder module" parameter, you specify how the encoder data that is
transferred to the DQ4HS module via module to module communication (MtM) is interpreted.
The selected encoder module/encoder channel must be identical with the configured
encoder module that supplies the encoder data.
Depending on which encoder module is being used, not only the encoder value but also the
value status of the encoder module and/or the direction of the encoder is included in the
supplied encoder data and processed in the cam control.
The following table shows the availability of value status and direction of the encoder
module:
