What to do if GE Inverter displays Modbus comms loss fault?
If the GE Inverter displays a Modbus comms loss fault, check the incoming Modbus RTU connection cable and ensure that at least one register is being polled cyclically within the timeout limit set in H-36 Index 3.
What to do if GE Inverter is overheating?
If the GE Inverter's heatsink is overheating, first, verify that the ambient temperature around the drive is within the specified limits. Ensure that cooling air can freely circulate around it. If necessary, improve panel ventilation. Make sure that the bottom entry and top exit vents are not obstructed.
What to check if GE Inverter shows DC bus ripple too high?
If the GE Inverter indicates that the DC bus ripple is too high, check that all incoming supply phases are present and balanced.
What to do if GE Inverter shows Brake channel over current?
If the GE Inverter reports a brake channel over current, check the external brake resistor condition and connection wiring.
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.
