Common Failures We Service

This unit is no stranger to stress in industrial environments. Here are some recurring breakdowns Flexa Systems resolves:

• Analog Input Drift: Inaccurate speed or torque reference over time.
• Drive Overload Fault: Excessive current draw due to motor mismatch or friction.
• Control Board Short: Burnt tracks or input damage from spikes or static.
• IGBT Failure: Output stage issues from heat, short-circuit, or wear.
• DC Bus Alarm: Excessive ripple or capacitor degradation triggering faults.
• Contactor Precharge Delay: Charging sequence stuck due to relay issues.
• Ground Leakage Detection: Earth path faults through motor cable insulation.
• Encoder Module Mismatch: Feedback errors due to incompatible modules.
• Memory Read Issues: Parameter set failure from aging EEPROM chips.
• Start Inhibit Not Resolved: Logic condition missing to allow soft start.
• Cooling Fan Failure: Internal fan stalls leading to overtemperature shutdowns.
• Fieldbus Timeout: Communication board not responding, often intermittent.
• Heatsink Sensor Alarm: Faulty thermistor or loss of contact with sink.
• Drive Ready but Won’t Run: External command lines inactive or miswired.
• Fault Code 16 / Trip Lockout: Latched fault conditions requiring reset sequence.
• Output Phase Imbalance: Worn contactors, bad motor windings, or dirty terminals.
• Analog Scaling Issues: Poor zero or span calibration leading to unstable speeds.
• Gate Drive Malfunction: Uneven switching pulses leading to fault trips.
• Power Supply Undervoltage: Faulty capacitors or unstable mains input.
• Vibration-Induced Relay Wear: Long-term use leading to intermittent logic faults.
• Reset Not Honored: Control logic locked due to external blocking signals.
