[PID ERROR]
The output upper limit setting value is smaller than
the output lower limit setting value.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set the values so that the output upper limit
setting value becomes larger than the output
lower limit setting value.
RUN: On
ERR.:On
CPU Status:Continue

[PID ERROR]
The input or output change rate alarm setting
value is smaller than 0.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set 0 or larger to the input or output change
rate alarm setting value.

[PID ERROR]
• The error at the start of auto tuning (step
response method) is 150 or less.
• The error at the end of auto tuning (step
response method) is 1/3 or more of the error at
the start of auto tuning.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Check the process value and set value, and
execute auto tuning again.
RUN: On
ERR.:On
CPU Status:Continue

[PID ERROR]
The operating direction estimated from the
process value at the start of auto tuning (step
response method) does not match the actual
operating direction output by auto tuning (step
response method).
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Correct the relationship among the set value,
manipulated value for auto tuning (step
response method), and process value, and
execute auto tuning again.
RUN: On
ERR.:On
CPU Status:Continue

[PID ERROR]
Auto tuning (step response method) does not
operate properly.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set the sampling time so that it will be longer
than the operation cycle, or set a larger value
for the input filter constant.
Change the settings, and execute auto tuning
again.
RUN: On
ERR.:On
CPU Status:Continue

[PID ERROR]
The output upper limit (ULV) for auto tuning (limit
cycle method) is smaller than the output lower limit
(LLV).
■Co
llateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set the values so that the output upper limit
(ULV) becomes larger than the output lower
limit (LLV).

[PID ERROR]
The PV threshold (hysteresis) setting value for
auto tuning (limit cycle method) is smaller than 0.
■Collateral information
• Common information: Program error location
• Individual information: -
■Diagnostic timing
• When instruction executed
Set 0 or larger to the PV threshold
(hysteresis) setting value.
