Example
Frequency at Qr = 382 Hz
Maximum frequency:
Set “Maximum frequency” to a value ≥ 382 Hz.
Recommendation. Round up to 400 Hz.
Minimum pulse width:
1 Hz corresponds to 1000 ms
382 Hz corresponds to 2.6 ms
1/(2 x “Frequency at Qr”) = 1.3 ms
Set “Minimum pulse width” to an integer value < 1.3 ms.
Recommendation: set 1 ms.
