Determine start position without position feedback
Calculate the standard deviation
200 SUT_GET_POI Find the point of inflection
Fine tuning is not possible. Pretuning will be executed first.
Calculate the standard deviation
Attempt to reach the setpoint with the maximum or minimum output value
400 TIR_CTRLN Attempt to reach the setpoint with the existing PID parameters
(if pretuning has been successful)
Determine oscillation and calculate parameters
Fine tuning not successful
