7.4  Speed control (P/PI) switching function

 

Relation

Speed control mode is normally controlled by 
proportional-integration compensation (Pi), which keeps the 
deviation between the actual speed and speed command 
becomes 0. Further, you can also achieve a propotional control 
function, which can be used as drooping operation (i.e. one load 
with several inverters) with this option card. 
Set P/PI switching function to one of the intelligent input terminal 1

∼

8 by the operator to achieve 

this function. (Input ‘43’ in one of C001

∼

C008.)  When this is turned on, control mode becomes 

proportion control (P). 
Please set proportional gain(Kpp ; a value used to decide the speed change rate)  to H052 by a 
digital operator. The relationship between the Kpp value and the speed change rate is shown 
below.
