D
This setting is valid when L3-05 is set to 1 or 2.
D
Normally it isn’t necessary to change this setting.
D
Decrease this setting when the motor capacity is small compared to the Inverter capacity or stalling
occurs when the motor is operated with the factory setting.(Set this current value as a percentage of
the Inverter’s rated current, i.e., 100% corresponds to the Inverter’s rated current.)

Set these constants when outputting one of the frequency agree or frequency detection signals from
a multi-function output. Table 7.13 shows the relationship between these constants and the output sig-
nals.

Fref/Set Agree 1
Frequency Detection 1
Frequency Detection 2
Set the speed that you want to detect in
Hz.
The set speed is an absolute value, so the
speed is detected in forward or reverse.

Frequency Detection 1
Frequency Detection 2
Set the speed detection range in Hz.
