Digital filter (from Firmware 02)

Digital filter (from Firmware 02)

The EL515x has a digital filter on encoder channels A and B that can be switched off (object Disable Filter, index: 0x80n0:08). This acts as a diffuse low-pass filter at about 100 KHz (equals 400,000 increments/second with 4-fold evaluation), i.e. the permissible limit frequency.

In each application it is advisable to check whether it would be advantageous to deactivate the filter - the detection of fast axis movements may be improved as a result.
