Parameter descriptions
654 Pulse Train Scaling Frequency
The pulse train (pulse sequence) signal at digital input IN2D (terminal X11.5) is scaled. Via parameter
Pulse Train Scaling Frequency 654, you can set which input frequency corresponds to the value of
Maximum Frequency 419. A read frequency of Maximum Frequency 419 means that at the pulse
train input, a frequency with the value of the scaling factor is applied.
Pulse Train Scaling Frequency
If parameter
Pulse Train Scaling Frequency 654 is set to zero, the frequency value at the digital
input will not be scaled.
Parameter
Repetition Frequency/Pulse Train 252 shows the actual value of pulse train input.
Pulse train signal on IN2D as reference value:

Output as percentage
In the case of a parameterization as a pulse train, the read frequency value is also available as a per-
centage for the reference percentage channel. 0 … 100% correspond to the signal frequency range 0
