11AFH PID operation
error
• The deviation when starting auto
tuning (step response method)
became 150 or less.
• The deviation when finishing auto
tuning (step response method)
was 1/3 or greater than the
deviation when starting.
Continue • Check and correct the control data.
• If the deviation when starting auto
tuning (step response method) is not
150 or more, specify a set value for
auto tuning.

• The movement direction assumed
from the relationship between the
set value and process value when
starting auto tuning (step
response method) and the output
value movement direction do not
match.
Continue • Perform auto tuning again after
correcting the relationship between the
set value, auto tuning (step response
method) output value, and process
value.
• Check and correct the control data.
