• Frame Type: IP20 – minimal protection
• Part Number: Parker 690+0020/230/1NN

Common Faults – We Handle Them All

Here’s a fresh take on the most frequent faults we repair in our lab for this Parker model:

• AC Input Phase Missing: Detected imbalance or dropped line on input terminals.
• High DC Bus Level: DC link voltage spikes due to regen braking or line surges.
• Low Voltage Under Load: Voltage sag under torque, often linked to poor supply or motor mismatch.
• IGBT Short Circuit: Power transistors blow under overload or heat stress.
• Drive Overheating: Heat sink or thermal sensor trips due to dust-clogged airflow or failed fan.
• No Encoder Feedback: Loss of signal from incremental encoder or resolver.
• Braking Faults: Even if not used, some drives still flag errors when braking circuit is unbalanced.
• Excessive Current Alarm: Output amps spike during motor ramp-up or deceleration.
• Emergency Stop Chain Broken: Safety loop is open or jumpered improperly.
• Analog Signal Fault: Input control range out of expected voltage/current specs.
• PLC Integration Loss: No comms over Modbus/Profibus, or handshaking mismatch.
• Gate Drive Anomaly: Control board can’t send correct pulses to switching transistors.
• Motor Overspeed Trip: Rotational feedback exceeds max configured frequency.
• Boot-up Error: Drive halts on initialization due to config corruption or firmware bug.
• Cap Bank Ripple Fault: Internal caps show high ripple – sign of aging or surge impact.
• Heatsink Sensor Open/Short: Bad thermal reading from heatsink probe or broken trace.
• Ground Leakage Alarm: Unexpected voltage present on motor frame or VFD housing.
• Processor Failure: Internal logic controller locks up, often from noise or power loss.
• 10V/24V Supply Out of Range: Control reference voltage not being regulated properly.
• Motor Temperature Trip: VFD halts due to excessive heat inside motor windings.
• Acceleration Failure: Load takes longer to ramp than allowable – triggers safety cutoff.

Flexa Systems Does It Right
