Description
Time required for only the differ-
ential (D) action to provide the
same manipulated variable as that
for the proportional (P) action. As
the differential time increases,
greater response is made to a
deviation change.
No differential control.
Y48 signal is output when the
absolute value of deviation amount
exceeds the deviation limit value.
No function
Select the operation to be per-
formed at the detection of upper,
lower, and deviation limit for the
measured value input. The opera-
tion for PID output suspension
function can be selected.
If the output frequency after PID
operation remains lower than the
Pr. 576 setting for longer than the
time set in Pr. 575, the inverter
stops operation.
Without output interruption func-
tion
Set the frequency at which the out-
put interruption processing is per-
formed.
Set the level (Pr. 577 minus
1000%) to release the PID output
interruption function.
