The operation timings of each signal are shown below.
E31, E32
Frequency Detection (Level and Hysteresis width) E36, E54 (Frequency Detection 2 and 3 (Level))
When the output frequency (estimated/detected speed) exceeds the frequency detection level specified by E31,
the "Frequency (speed) detected signal" comes ON; when it drops below the "Frequency detection level minus
Hysteresis width specified by E32," it goes OFF.
The following three settings are available.
