- Analog Input Start Frequency (C16) C16 specifies the start frequency of inverter when F01=1 as follows:
0:
Select Value in C12; 1: Select 0 Hz.
C16 determines the analog input frequency reference (D17) for any analog voltage input below C12.
- Analog Input Low-pass Filter Gain (C17)
C17 specifies the number of sampling of filter analog input to help reducing noise on signal

Protective functions

Current limitation
When the output current of the inverter exceeds the level specified by the current limiter (F26), the inverter
automatically manages its output frequency to prevent a stall and limit the output current. (Refer to the
paragraph 2.5.2 Instantaneous over-current limitation)
If F25 = 1, the current limiter is enabled only during constant speed operation. If F25 = 2, the current limiter
is enabled during both of acceleration and constant speed operation. Choose F25 = 1 if you need to run the
