• 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 output ON simultaneously with or before
starting operation of the E5AZ/E5EZ.

• This parameter sets the output period. Set the control period taking the
control characteristics and the electrical life expectancy of the relay into
consideration.
• In a standard control system, use the "control period (OUT1)" parameter.
The "control period (OUT2)" parameter cannot be used.
• In a heating/cooling control system, the control period can be set inde-
pendently for heating/cooling. Use the "control period (OUT1)" parameter
to set the heating side control period, and use the "control period (OUT2)"
parameter to set the cooling side control period.
• Whenever control output 1 is the current output, "control period (OUT1)"
cannot be used.
