code
11A1H PID operation • A value outside the range ( < 0

error was specified for the integral time
(T ).

error was specified for the derivative
time (T
11A6H PID operation • A value less than or equal to the
error operation cycle was specified for
the sampling time (T
11A7H PID operation • A process value variation (PV)
error overflow occurred.
11A8H • A deviation (EV) overflow
occurred.
11A9H • An integral calculation value
overflow occurred.
11AAH • A derivative gain (K
overflow occurred.
11ABH PID operation • A differential calculation value
error overflow occurred.
11ACH • A PID operation result overflow
occurred.
11ADH PID operation • A value smaller than the output
error lower limit setting value was
specified for the output upper limit
setting value.
11AEH PID operation • A value smaller than 0 was
error specified for the input variation
amount warning setting value or
output variation amount warning
setting value.
11AFH PID operation • The deviation when starting auto
error 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.
11B0H PID operation • The movement direction assumed
error 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.
11B1H PID operation • The input value (PV) did not
error change correctly, and auto tuning
(step response method) did not
function normally.
11B2H PID operation • A value equal to or lower than the
error output lower limit (LLV) was
specified for the auto tuning (limit
cycle method) output upper limit
(ULV).
