z
Rapidly stabilizing control status
To rapidly stabilize the control conditions even when overshooting occurs, shorten the integral
time and lengthen the differential time.
z
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.

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.
