Conditions which will cause the autotuning to stop:
When the temperature set value (SV) is changed.
When the memory area is changed.
When the PV bias value is changed.
When the AT bias value is changed.
When transfer to Manual mode using the Auto/Manual transfer.
When the measured value (PV) goes to input error range [Measured value (PV) Input error
determination point (high) or Input error determination point (low) Measured value (PV)].
When the power is cut off.
When FAIL occurs in the module whose channel is under the autotuning. Otherwise, when FAIL
occurs in the H-PCP-J module.
When transfer to the PID control mode by the PID/AT transfer.
When operation mode is set to “Unused,” “Monitor” or “Alarm.”
When the Control RUN/STOP function is changed to the “Control STOP” function.
When the above-mentioned conditions to stop the autotuning occurs, the autotuning is
immediately stopped and switch over to the PID control mode. The PID constants
return to the values at the start of the autotuning.
