Note: The output frequency results from the parameter setting.
=> See also firmware Functional Description: "Encoder
Emulation".
Note: Conditionally due to the internal signal processing the period
duration and the duty cycle of the signals put out vary.
Therefore the following requirements of the signal filtering for
UA1 and UA2 arise.
f
≥ 500 kHz f
Pass
≥ 1 MHz
f < 500 kHz f
Pass
≥ 2 x f
Note: The evaluation electronics of the control must be able to
process the maximum output frequency of 1 MHz. Otherwise
not all of the signal pulses can be evaluated.
Note: The frequency measurement is not suitable for the RPM
measurement derived from the incremental emulator signals.
