Switching hysteresis of the frequency threshold Qmin
Question:
How many Hz has the switching hysteresis of the programmable frequency threshold Qmin (C0017)?
Answer:
The programmable frequency threshold Qmin (C0017) has a switching hysteresis of 0.5 Hz. If e. g. a value of 5 Hz is entered in code C0017, the signal PCTRL1-QMIN will switch to HIGH-level as soon as the output frequency is 5.5 Hz. If the frequency threshold is exceeded once (PCTRL1-QMIN = HIGH) and the output frequency is reduced, the signal PCTRL1-QMIN will switch back to LOW-level as soon as the frequency threshold entered in code C0017 is reached (in this example in case of 5 Hz).
