DIFFERENTIAL (D) TIME, AND PID LIMIT:



DIFFERENTIAL (D) TIME
it is the integral timed of d control . the unit is second . d, control is not performed when the setting  is  0.00
NOTE: the response of pid control is subject to proportional gain  integral time and differential time   .in actual debugging , to to optimize the operational ,please modify the responsiveness with load , when it is set to be  0.00 , control  (p,i,d control ) will not act.

PID LIMIT:

set this constant as a percentage of the maximum  output frequency , with the maximum frequency taken as  100% constant b,5-0,6 prevents the the frequency  reference after pid control from exceeding  the fixed value.
