Issue:
Needs to adjust the voltage boost, on an ATV312 drive.
Product Line:
ATV312
Environment:
All
Cause:
Need for more voltage on startup.
Resolution:
Go to SEt menu
[IR compensation] 0 to 100% default is 20%
- For [U/F mot 1 selected] (UFt) = [SVC] (n) or [Energy sav.] (nLd), : IR compensation
- For [U/F mot 1 selected] (UFt) = [Cst. torque] (L) or [Var. torque] (P), : Voltage boost
Used to optimize the torque at very low speed (increase [IR compensation] (UFr) if the torque is insufficient).
Check that the value for [IR compensation] (UFr) is not too high when the motor is in a hot state otherwise some
instabilities can occur.
Note: Changing [U/F mot 1 selected] (UFt), will cause [IR compensation] (UFr) to return to its factory setting (20%).
