Function: Timer Output
Setting: 12
This Timer function, that is built into the Drive, is independent of the rest of the Drive operation, i.e. there is no requirement
for a Run command for the timer to operate. A Timer digital output will close b4-01 seconds after a digital input configured as
Timer Input (H1-0x= 18) closes and remains closed. The Timer digital output will remain closed for b4-02 seconds after the
Timer digital input opens and remains open.
Refer to the descriptions of parameters b4-01 and b4-02 for a timing chart of the Timer function.
Function: Fref/Fout Agree 2
Setting: 13
The "Fref/Fout Agree 2" output will close whenever the actual output frequency is within the Speed Agree Width (L4-04) of
the current frequency reference regardless of the direction.
Function: Fref/Fset Agree 2
Setting: 14
The "Fref/Set Agree 2" output will close whenever the actual output frequency and the frequency reference are within the
Speed Agree Width (L4-04) of the programmed Speed Agree Level (L4-03). This Fref/Fset Agree 2 output is direction
sensitive according to the direction programmed in L4-03.
Function: Freq Detect 3
Setting: 15
A "Freq Detect 3" output will be closed whenever the output frequency is equal to or below the value of the programmed
Speed Agree Level (L4-03). The Speed Agree Width (L4-04) is the hysteresis to the Freq Detect 3 function. Whenever the
output frequency approaches the Speed Agree Level while accelerating it will need to be equal to or exceed the Speed Agree
Level (L4-03) plus the Speed Agree Width (L4-04) before the Freq Detect 3 output will energize.
As the output frequency approaches the Speed Agree Level while decelerating, the Freq Detect 3 output will de-energize
exactly at the Speed Agree Level.
This Freq Detect 3 output is direction sensitive according to the direction programmed in L4-03.
Function: Frequency Detection 4
Setting: 16
A Frequency Detect 4 output will be closed whenever the output frequency is equal to or above the value of the programmed Speed
Agree Level (L4-03). The Speed Agree Width (L4-04) is the hysteresis to the Freq Detect 4 function. Whenever the output frequency
approaches the Speed Agree Level (L4-03) while accelerating it will de-energize exactly at the Speed Agree Level.
As the output frequency approaches the Speed Agree Level while decelerating, the Freq Detect 4 output will
de-energize when the output frequency is equal to or below the Speed Agree Level (L4-03) minus the Speed Agree Width (L4-04).
This Freq Detect 3 output is direction sensitive according to the direction programmed in L4-03.
