Differential Gains to zero and increase the Proportional Gain Parameter 77 until the system becomes unstable then lower the gain until the system stabilizes again Set the Proportional Gain about 15 less than that value that stabilizes the system If only Proportional Gain is used and the system is operating in a steady state condition set point is fixed and process variable has settled to a fixed value there will always be a certain amount of error in the system This is called the steady state error Integral Gain Parameter 78 is used to force the steady state error to zero by increasing the output speed command with respect to time Over time the error will be forced to zero because the Integral term will continue to change the speed command even after the Proportional term reaches steady state and no longer affects the speed command The Integral Gain affects the rate of rise of the output speed command from the Integral term Small amounts of Integral Gain can cause large changes in PID performance so care must be taken when adjusting Integral Gain Too much Integral Gain will result in overshoots especially if large step changes in error occur Typically Proportional and Integral Gain are all that is needed to fine tune the system However it may be necessary to use Differential Gain Parameter 79 to further stabilize the system especially when quick responses are required The Differential term responds to the rate of change o
