CHAPTER 5 PARAMETERS
Initial Setting Level
ST self-tuning
• The ST (self tuning) function executes tuning from the start of program execution
to calculate PID constants matched to the control target. When the ST function is in
operation, be sure to turn the power supply of the load connected to the control out

Control period (OUT2)
• This parameter sets the output period. Set the control period taking the control char
acteristics and the electrical life expectancy of the relay into consideration.
• In a standard control system, use the control period (OUT1)" parameter. The con

trol period (OUT2)" parameter cannot be used.
• In a heating and cooling control system, the control period can be set independently
for heating and cooling. Use the control period (OUT1)" parameter to set the heat
ing side control period, and use the control period (OUT2)" parameter to set the
cooling side control period.
