5.3 Description of Function Codes 5.3.2 E codes (Extension terminal functions)
5-174
E31, E32
Frequency detection (level and hysteresis width)
Related function codes: E36 (Frequency detection 2, level),
E54 (Frequency detection 3, level)
When the output frequency exceeds the frequency detection level specified by E31, the “Frequency (speed)
detection 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.
