8. Fast counters in the ecomat R 360
The controller ecomat R 360 has a total of 8 fast inputs which
can process input frequencies up to 50 kHz. Apart from
measuring the frequency at the inputs FRQ0...FRQ3 the inputs
ENC0 to ENC3 can also be used to evaluate encoders (counter
functions) with a maximum frequency of 10 kHz.
The functions FREQUENCY and INC_ENCODER are available
for simple evaluation.
If the fast inputs of the ecomat R 360 are used as "normal"
digital inputs the increased sensitivity to noise has to be
taken into account (e.g. contact bouncing in the case of
mechanical contacts). The standard digital input has an
input frequency of 50 Hz. If required, the input signal has
to be debounced by means of the software.
