Speed Agree Level
(Absolute value)
Fref/Set Agree 1
Frequency Detection 1
Frequency Detection 2
Set the frequency (or motor speed) that you
want to detect in Hz.
The set speed is an absolute value, so the
speed is detected in forward or reverse.
Speed Agree Width
(Absolute value)
Fref/Fout Agree 1
Fref/Set Agree 1
Frequency Detection 1
Frequency Detection 2
Set the frequency (or motor speed) detec-
tion range in Hz.
Speed Agree Level

Fref/Set Agree 2
Frequency Detection 3
Frequency Detection 4 Set the frequency (or motor speed) that you
want to detect in Hz.
Set positive values for forward, negative
values for reverse.

Set the frequency(or motor speed) detec-
tion range in Hz.
D
Set the corresponding setting in the multi-function output (H2-01, H2-02, or H2-03) to output the de-
sired Fref/Fout Agree signal, Fref/Set Agree signal, or Frequency Detection signal.
