- LlmorganSep 23, 2025
Press the stop key. If the fault persists, consult you supplier.
What to do if GE AF-70 LP Inverter shows Internal memory fault (DSP)?
Press the stop key. If the fault persists, consult you supplier.
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.
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.
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 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 to do if GE Inverter shows Internal memory fault (IO)?
Press the stop key. If the fault persists, consult you supplier.
What to do if GE Inverter is too cold?
If the GE Inverter indicates an under temperature condition, the ambient temperature is less than -10°C. Raise the temperature above -10°C to start the drive.
What to do if GE AF-70 LP displays Motor PTC thermistor trip?
If the GE Inverter indicates a Motor PTC thermistor trip, it means the connected motor thermistor has detected an over temperature condition. Check the wiring connections and the motor itself.
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 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.
