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!
