 Take caution when the following condition is satisfied because the inverter recognizes the deviation value as
a negative (positive) value even though a positive (negative) deviation is given:
Pr. 934 PID display bias coefficient > Pr. 935 PID display gain coefficient
To perform a reverse operation, set the forward operation in Pr. 128 PID action selection . To perform a forward
operation, set the reverse operation in Pr. 128 . In this case, the PID output shutoff release level is (1000 - Pr.
577 ).
(Example) Set the following:
Pr. 934
= "500" and
20% (4mA is applied),
Pr. 935
= "100"
and 100% (20mA is applied).
When the set point=400 and the
measured value=360, the deviation is
+40 (>0), but the inverter recognizes the
deviation with -10% (<0). Because of
this, operation amount does not
increase in the reverse operation
setting.
The operation amount increases when
the forward operation is set.
To perform PID output shutoff release at
deviation of +40 or higher, set
Pr. 577
=
"960."
(12) Analog input display unit changing (Pr. 241)

You can change the analog input display unit (%/V, mA) for analog input bias/gain calibration.

Depending on the terminal input specification set to Pr. 73 , Pr. 267 , and voltage/current input switch the display
units of C43(Pr. 934), C45(Pr. 935) change as shown below.

If the Pr.241 setting is changed, the increments of the C3(Pr.902) , C4(Pr.903) , C6(Pr.904) , and C7(Pr.905) are
also changed. ( Refer to page 189 )
