PROPORTIONAL GAIN (P), AND INTEGRAL (1) LIMIT.




PROPORTIONAL GAIN (P),
set the proportional gain of p control as multiples. the integral time of  I control is in unit of seconds.
NOTE:
the response of pid control is subject to proportional gain,integral time and different time. in the event of actual debugging , the response should be adjust when the load is operating to achieve the best operation state . 

INTEGRAL (1) LIMIT.
it is used to set the upper limit of control in unit of % with max . frequency taken as 100 %.
NOTE:
it is the  constant which limits the calculated value of integral control to be within a certain range in pid control . there is normally no need to change the default setting . reduce the setting if there is a risk of load damage , or of the motor going out of step , by inverters response when the load suddenly changes . if the setting is reduced too much , the target value and the feedback value will not match.
