Stall Prevention
Current level can be setting (It can be set separately in acceleration or constant speed; it can be set with or
without protection in deceleration)
Instantaneous Over Current
(OC) and Output Short-
Circuit (SC) Protection
Inverter stops when the output current exceeds 160% of the inverter rated current
Inverter Overload Protection
(OL2) If inverter rated current 120%/1min is exceeded, inverter stops. The factory default carrier frequency is
2~4KHZ

Motor Overload Protection
(OL1)
Electrical overload protection curve
Over voltage (OV)
Protection
If the main circuit DC voltage rises over 820V, the motor stops running.
Under voltage (UV)
Protection
If the main circuit DC voltage falls below 380V, the motor stops running.
Auto-Restart after
Momentary Power Loss Power loss exceeds 15ms.
Auto-restart function available after momentary power loss in 2 sec.
Overheat(OH) Protection Use temperature sensor for protection.
Ground Fault (GF)
Protection
Use current sensor for protection.
DC Bus Charge Indicator When main circuit DC voltage ≥ 50V, the CHARGE LED turns on.
Output Phase Loss (OPL)
Protection
If the OPL is detected, the motor stops automatically.
