PID control
* When both
Pr.934
and
Pr.935
are set to a value other than "9999," the set point of D9248 and
the measured value of D9249 are set with coefficients. The setting range for the devices are
from the smaller coefficient to the larger coefficient of
Pr.934
and
Pr.935
.
(Refer to the
Instruction Manual of the inverter
for the details of
Pr.934
and
Pr.935
.)

Description
D9248 PID set point / PID deviation
Set point:
0 to 100%*
Deviation value:
-100 to 100%
Set the PID set point or PID
deviation (0.01% increments*)
D9249 PID measured value
0 to 100%*
Set the PID measurement
value (0.01% increments*)
D9250 PID manipulated variable
-100 to 100%
Stores the PID manipulated
variable (0.01% increments)
D9255 PID operation control
0
PID operation stop
1
PID operation start
CAUTION
•
The PID set point/PID deviation value of D9248 automatically switches over
by
Pr. 128
setting.
•
If
Pr. 128
is set to deviation input (70, 71, 90, 91), setting value of PID
measured value (D9249) is made invalid.
•
Operates in the maximum value (the minimum value) of the setting range if
the value outside the range is set.
