Filter

The filters of all channels are disabled on delivery.

The filter can be used to hide short signal jumps (spikes). They are regarded as invalid.

Enabling a filter

1. Enable the filter via the CoE parameter 0x80n0:01 "Enable digital filter".

2. Set the filter time via the parameter 0x80n0:14 "Digital filter counter".
Pulses that are shorter than the filter time are ignored. The filter time must be specified in microcycles. A "1" equals a disabled filter.

3. Check whether the macrocycle is smaller than the EtherCAT cycle time due to the selected settings.
The current macrocycle time can be read in CoE parameter 0xF900:08 "CycleTime". As a rule, it should be 20 % lower than the EtherCAT cycle time.
