Digital frequency extension module | Parameter setting & configuration

Digital frequency output

Parameter setting

3.2.5 Frequency limitation

In C13053

/ C14053 a frequency limitation can be set for the digital frequency output.

 If the frequency is limited, a fault message is generated and the response set in C13080

/ C14080

is executed.

– At the same time the output DFOUT_bOutputFreqLimited of the system block

LS_DigitalFrequencyOutput is set to TRUE.

 The hardware limits the digital frequency output to 500 kHz.

3.2.6 Touch probe

When the zero pulse occurs on track Z - Z

, a touch probe is triggered.

 The corresponding signals to execute touch probe processing are available via the

system block LS_TouchProbeDFOUT.

 In C13061

/ C14061 a delay time can be set for the touch probe.

 If a touch probe has been triggered, the output DFOUT_bTouchProbeReceived is set to

TRUE for one cycle.

 Tip!

Detailed information on touch probe processing can be found in the online

documentation for the controller in chapter "I/O terminalsTouch probe

detection".

 Note!

• Due to the remainder processing implemented in the 4 kHz control cycle, only

settings ≥ 4 kHz are reasonable for frequency limitation!

• If the digital frequency input is directly connected to the digital frequency

output, the set frequency limitation is without function!
