Reducing long-cycle oscillation
If oscillation occurs with a longer cycle than the integral time setting, it means that
integral operation is strong. The oscillation will be reduced as the integral time is
lengthened.
Figure 6.30 Reducing long-cycle oscillation diagram.
z
Reducing short-cycle oscillation
If the oscillation cycle is short and oscillation occurs with a cycle approximately the same
as the differential time setting, it means that the differential operation is strong. The
oscillation will be reduced as the differential time is shortened.
Figure 6.31 Reducing short-cycle oscillation diagram.
If oscillation cannot be reduced even by setting the differential time to 0, then either
lower the proportional gain or raise the PID primary delay time constant.
