1.
Set "Method selection" to "Param write" of the control mode to be used.

stations"[CC IE Field Configuration][Online][Parameter Processing of Slave Station]
2.
Set "CH Cooling system setting".
● An auto tuning calculation formula to find PID constants is determined based on this setting; therefore, configure this
setting before executing auto tuning.
● "Air Cooled" and "Water Cooled" roughly indicate the level of the cooling ability. When a device is too cooled even if it is
set to air cooled, set the module to Water cooled (1H). When a device is not very cooled even if it is set to water cooled,
set the module to Air cooled (0H).
● In general, the ability of water cooling is higher than that of air cooling and cooling may be too strong if the same PID
constants as air cooling are used. Some time is required until the control becomes stable upon the initial start-up,
disturbance, or setting change. Therefore, in auto tuning, PID constants for when the module is set to Water cooled (1H)
become larger than those for when the module is set to Air cooled (0H).
