OVER LOAD CURRENT IN VFD
I HAVE MOTOR-189 AMP
ACS 880 VFD -260 AMP
CAN I OPEN OVERLOAD LIMIT TILL 276 AMP.
First, it would be important to understand why you want to open a current limit up to 276 A.
The nominal current of the electrical motor is 189A, so at 500V drive that delivers 260 A should be more than enough.
If you don't say why you need 276 A, I can't give you an alternative suggestion ...
In any case, you can try to enable parameter 30.15 and see if you can set the maximum current you want on parameter 30.16 - 30.17
The physical current limit that the drive can supply is defined by the HW characteristics.
These are operations that require a specific competence and for which, in my opinion, the possible secondary effects must be carefully evaluated before.
