Why does my VFD fault on overcurrent when the motor starts?
A VFD overcurrent fault at startup usually means the motor draws more current than the drive's limit, often due to excessive acceleration…

Why does my VFD fault on overvoltage during deceleration?
Your VFD faults on overvoltage during deceleration because the motor acts as a generator, pumping energy back into the DC bus faster…

Why does my VFD show an overcurrent fault at startup but run fine after reset
An overcurrent fault at startup usually means the VFD's acceleration ramp is too short for the motor's inertia, causing a current spike…

Why does my VFD show ground fault error on startup
A VFD ground fault on startup usually means insulation breakdown in the motor windings or cables, moisture in the conduit, or a…

Why does my VFD show overcurrent fault at startup
A VFD overcurrent fault at startup usually means the motor is drawing too much inrush current because the acceleration ramp is too…

Why does my VFD show overcurrent fault at startup but runs fine after reset?
A VFD overcurrent fault at startup usually means the motor draws excessive inrush current during acceleration, often caused by too-short acceleration time,…

Why does my VFD show overcurrent fault at startup only
A VFD overcurrent fault at startup usually means the motor's inrush current exceeds the drive's limit, often caused by too-short acceleration ramps,…

Why does my VFD trip on ground fault only during motor startup
A VFD that trips on ground fault only during startup usually indicates insulation breakdown in the motor windings or cables that only…
