Parameter
Automatic Filter Adjustment
Hunting Monitor Period*
* These parameters are displayed when 2-PID control or standard control (not heating/cooling control) is
selected.
 Parameters
• Automatic Filter Adjustment (fa)
This parameter is used to execute automatic filter adjustment.
• Input Digital Filter (inf)
The set value of this parameter is used by a digital filter through which the sensor input passes to
create a stable input value even when the sensor input value fluctuates due to noise. This param-
eter is automatically set when automatic filter adjustment is used.
• Automatic Filter Adjustment Seal Period (fasp)
This is the period of small temperature variations (up to several seconds) that occur in one seal.
Normally, use the default for this parameter.*
• Automatic Filter Adjustment Hunting Monitor Period (fahp)
This is the period of large temperature variations (several tens of seconds or longer) when
packing.
Normally, use the default for this parameter.
If tuning for the automatic filter adjustment continues indefinitely or tuning requires a long time,
measure the temperature waveform to set this parameter.*
* If tuning for the automatic filter adjustment continues indefinitely or tuning requires a long time, measure the
temperature waveform to set this parameter according to the frequency of oscillation.
 Operating Conditions
Operation is possible when all of the following conditions are met.
• Startup Conditions
Automatic filter adjustment will start when all of the following conditions are met.
• The PID ON/OFF parameter must be set to
"PID."
• The Standard or Heating/Cooling parameter
must be set to "Standard."
• The Auto/Manual parameter must be set to
"Automatic."
• Restrictions during Execution
During automatic filter adjustment, the settings of other parameters cannot be changed in the
same way that they cannot be changed during auto-tuning.
However, the following parameters can be changed.
• Auto/Manual
• Communications Writing
• RUN/STOP
Automatic filter adjustment will be cancelled in the following cases. The value of the Input Digital
Filter parameter that was set during adjustment will not be saved.
