To suppress a minor sustained oscillation due to the manipulated variable quantization (for
example, in pulse width modulation with PULSEGEN) a dead band is applied to the
(DEADBAND) control deviation. With DEADB_W = 0.0, the dead band is disabled. The
effective control deviation is indicated by the ER parameter.
The following figure shows the block diagram of the PID algorithm.
