Set Values
•This parameter is used to set the electronic thermal protection constant of motor over -
load detection OL1.
•The default setting does not need any changes in normal operation.
•To
set the parameter according to the characteristics of the motor , confirm the thermal
time constant with the motor manufacturer and set the parameter with some margin. In
other words, set the value a little shorter than the thermal time constant.
•To
detect motor overloading more quickly , reduce the set value, provided that it does
not cause any application problems.
