LSE AC Drive Inverter Overload Protection
When the inverter input current exceeds the rated current, a protective function is activated to prevent damages to the inverter based on output current inverse - time proportional characteristics.
If the inverter motor protections are set properly, the following below are minimum drive parameter settings:
BA.13 - Motor Nameplate FLA
BA.15 - Motor Nameplate voltage
BA.19 - Utility voltage provided to the inverter.
- Load Duty drive parameter setting is PR.04 (ALL LSE AC Drives except H100+ is PR.02).
- All drives are factory set to Heavy-Duty (HD), except H100 drive which his Normal Duty (ND).
- Any LSE AC Drive Model Load Duty can be changed to (ND) except the M100 and S100N4X (HD) model only.
- Output Relay can be programmed to toggle on "IOL" Inverter Overload, settings below from table in S100 manual:
