The control program compares the absolute value of
parameter 71.04 Deviation act value
defined by this parameter. If the absolute value is within the
deadband range for the time period defined by parameter
71.40 Deadband delay, PID's deadband mode is activated
and 71.06 PID status word
PID's output is frozen and
frozen is set.
If the absolute value is equal or greater than the deadband
range, PID's deadband mode is deactivated.
Range
Defines the deadband delay for the deadband function. See
parameter 71.39 Deadband
