100.0% Yes A 1AAH
b5-07
PI offset adjust-
ment
Sets the offset after PI-control as a per-
centage of the maximum output fre-
quency.
-100.0
to
+100.0
0.0% Yes A 1ABH
b5-08
PI delay time
constant
Sets the time constant for low pass filter
for PI-control outputs in 1-second units.
Usually not necessary to set.
0.00 to
10.00
0.00 s Yes A 1ACH
b5-09
PI output char-
acteristics selec-
tion
Selects forward/reverse direction for PI
output.
0: PI output is forward.
1: PI output is reverse
0 or 1 0 No A 1ADH
b5-10 PI output gain Sets output gain.
0.0 to
25.0
1.0 No A 1AEH
b5-11
PI reverse output
selection
0: Limit to 0 when PI output is negative.
1: Reverses when PI output is negative.
Limit to 0 is also active when reverse pro-
hibit is selected by
b1-04.
0 or 1 0 No A 1AFH
b5-12
Selection of PI
feedback signal
loss detection
0: No detection of PI feedback loss.
1: Detection of PI feedback loss.
Operation continues during detection,
the fault contact is not operated.
2: Detection of PI feedback loss.
The motor coasts to stop at detection,
and the fault contact operates.
0 to 2 0 No A 1B0H
b5-13
PI feedback loss
detection level
Sets the PI feedback loss detection level
as percentage using the maximum output
frequency as 100%.
