Set these parameters when outputting one of the frequency agree or frequency detection signals from
a multi-function output (settings 2, 3, 4, 5, 13, 14, 15, or 16). The following table shows the relationship
between these parameters and the output signals.
Parameter Related output settings Parameter function
Speed Agree Level
(Absolute value) Fref/Set Agree 1 (setting 3)
Frequency Detection 1 (setting 4)
Frequency Detection 2 (setting 5) 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.
Speed Agree Width
(Absolute value) Fref/Fout Agree 1 (setting 2)
Fref/Set Agree 1 (setting 3)
Frequency Detection 1 (setting 4)
Frequency Detection 2 (setting 5) Set the speed detection range in Hz.
Speed Agree Level +/–
(Signed value) Fref/Set Agree 2 (setting 14)
Frequency Detection 3 (setting 15)
Frequency Detection 4 (setting 16) Set the speed that you want to detect in Hz.
Set positive values for forward, negative
values for reverse.
Speed Agree Width +/–
(Signed value) Fref/Fout Agree 2 (setting 13)
Fref/Set Agree 2 (setting 14)
Frequency Detection 3 (setting 15)
Frequency Detection 4 (setting 16) Set the speed detection range in Hz.
•
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. There is a timing
chart showing the operation of these signals on the following page.
