Output frequency detection
 Output up-to-frequency sensitivity (SU signal, Pr.41)
The inverter output frequency is detected and output as output signals.
Pr. Name Initial value Setting range Description
41
M441 Up-to-frequency
sensitivity
10% 0 to 100% Set the level where the SU signal turns ON.
42
M442 Output frequency
detection
6 Hz 0 to 590 Hz Set the frequency where the FU (FB) signal turns ON.

M443
Output frequency
detection for reverse
rotation
9999
0 to 590 Hz
Set the frequency where the FU (FB) signal turns ON in
reverse rotation.
9999 Same as the Pr.42 setting.

M445 Third output frequency
detection
60 Hz 0 to 590 Hz Set the frequency where the FU3 (FB3) signal turns ON.
865
M446
Low speed detection
1.5 Hz 0 to 590 Hz Set the frequency where the LS signal turns ON.
870
M400 Speed detection
hysteresis
0 Hz 0 to 5 Hz Set the hysteresis width for the detected frequency.
• Up to frequency (SU) is output when the output frequency reaches the set
frequency.
• The Pr.41 value can be adjusted within the range ±1% to ±100%
considering the set frequency as 100%.
• This parameter can be used to check that the set frequency has been
reached, and provide signals such as the operation start signal for related
equipment.
