CHAPTER 5 PARAMETERS
E5GN
5–22
ST self-tuning
The control must be set to temperature input
and 2-PID control.
Ă• The ST (selfĆtuning) 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 outĆ
put ON simultaneously with or before starting operation of the E5GN.

Control period (OUT1)
Control period (OUT2)
The control must be set to 2-PID control.
Ă• This parameter sets the output period. Set the control period taking the control charĆ
acteristics and the electrical life expectancy of the relay into consideration.
Ă• In a standard control system, use the control period (OUT1)" parameter. The conĆ
trol period (OUT2)" parameter cannot be used.
Ă• 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 heatĆ
ing side control period, and use the control period (OUT2)" parameter to set the
cooling side control period.
Parameter Setting Range Unit Default
Control period (OUT1) 1 to 99 Second 20
Control period (OUT2) 1 to 99 Second 20
