What should I do if my GE AF-70 LP Inverter shows an Input phase loss trip?
If the GE Inverter displays an Input phase loss trip, verify that all incoming power supply phases are present and balanced.
How to fix Autotune Fault on GE Inverter?
An Autotune Fault on the GE Inverter indicates that the motor parameters measured during autotune are incorrect. Check the motor cable and connections for continuity and ensure all three phases of the motor are present and balanced.
Why GE Inverter shows Over voltage on DC bus?
If the GE Inverter displays an 'Over voltage on DC bus' error, verify that the supply voltage is within the drive's allowed tolerance. If the fault occurs during deceleration or stopping, increase the deceleration time in F-04 or install a suitable brake resistor and activate the dynamic braking function with H-34.
How to resolve Output Fault on GE AF-70 LP?
An Output Fault on the GE Inverter suggests a problem on the drive's output, such as a missing phase or imbalanced motor phase currents. Inspect the motor and its connections.
What causes Motor Thermal Overload (I2t) on GE AF-70 LP?
The GE Inverter trips with a 'Motor Thermal Overload (I2t)' when it has delivered >100% of the value set in F-08 for an extended period, preventing motor damage.
How to fix Power stage trip on GE Inverter?
To address a power stage trip on the GE Inverter, check for short circuits on the motor and connection cable.
Why GE AF-70 LP Inverter shows Under voltage on DC bus?
An 'Under voltage on DC bus' error on your GE Inverter indicates that the incoming supply voltage is too low. This often occurs when power is removed from the drive. However, if it happens during operation, check the incoming power supply voltage and all components in the power feed line to the drive.
