 Setting the notification zone of the output frequency reaching the set
point (SU signal, Pr.41)
• The Up to frequency (SU) signal is output when the output frequency reaches the set frequency.
• The value can be adjusted within the range ±1% to ±100% considering the set frequency as 100%.
Pr.41
• It may be useful to use this signal to start operating related equipment after checking that the set frequency has been
reached.

Output current detection function

If the inverter output current which reaches a specific value is detected during operation, the relative signal is output via an
output terminal.

Description
Set the level where the SU signal turns ON.
Set the frequency at which the FU signal turns ON.
Set the frequency at which the FU signal turns ON only while the
motor rotates in reverse direction.
Same as the Pr.42 setting.
Description
Set the output current detection level. Consider the value of the
rated inverter current as 100%.
Set the output current detection time. Enter the delay time
between the time when the output current reaches the set
current or higher and the time when the Output current
detection (Y12) signal is output.
Select the inverter operation at the time when the Y12 signal
turns ON.
