Handling Precautions
• Auto-tuning does not operate normally when the equipment to be
controlled is not connected.
• The time required for auto-tuning depends on the equipment controlled.
• When auto-tuning is executed, control is terminated , lower and higher
limit outputs are repeated several times and PV fluctuates. When
equipment failure may be caused by PID fluctuations, set the PID value
manually.
If just PID value can not be got in case of control object, sets PID value
with manual.
•A variable parameter PA08 setting makes values set at the start of auto-
tuning valid. A change in the PA08 setting made during auto-tuning
execution is ignored. The new value is valid in the next auto-tuning
operation.
