Chapter 5 Function Code
E31, E32 Frequency Detection (Operation Level and Hysteresis Width)
Related Function Code: E36, E54 Frequency Detection 2, 3 (Operation Level)
This function outputs an ON signal when the output frequency is same or above the operation level set by
the frequency detection. When the output frequency decreases to below the [frequency detect operation
level - hysteresis width], the signal turns off.
The following three settings are available by the frequency detect 2 and 3.
