• 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

Description
Set the level where the SU signal turns ON.
Set the frequency where the FU (FB) signal turns ON.
Set the frequency where the FU (FB) signal turns ON in
reverse rotation.
Same as the Pr.42 setting.
Set the frequency where the FU2 (FB2) signal turns ON.
Set the frequency where the FU3 (FB3) signal turns ON.
Set the frequency where the LS signal turns ON.
Set the hysteresis width for the detected frequency.
