Top Faults We Service on This Unit ⚠️
- ⚡ DC overvoltage during fast braking or when resistor path is open
- 🔋 Undervoltage trips caused by weak or unstable power supply
- 🚨 Motor overcurrent from short circuits, improper tuning, or heavy torque spikes
- 🌡️ Heatsink temperature trips from poor airflow or fan failure
- 🛑 Motor stall errors due to underconfigured current limit or excessive load
- 🔥 Brake resistor overloads caused by frequent or rapid deceleration
- 💣 Brake switch overuse failure — often after high braking duty cycles
- 📡 Communication loss from misconfigured COMMS timeout or damaged cable
- 🛑 STO safety input issues or intermittent faults from wiring degradation
- 🔁 Control-to-power communication sync errors from firmware instability
- 🎯 Speed feedback faults from encoder signal loss or parameter mismatch
- ⚠️ Current limit exceeded under acceleration or torque overshoot
- 🔌 24V power rail undervoltage caused by external short circuit
- ⚡ Phase loss trips due to wiring issues or internal damage
- 💥 DESAT (Over-I) — typically means damaged IGBTs or blown gate driver
- 🔄 High DC bus ripple due to failing capacitors or missing input phase
- 🧨 Brake resistor circuit trip — usually a wiring error or overload
- 🚀 Overspeed alarms from unstable feedback or encoder malfunction
- 📏 Analog input misreadings — sensor failure or incorrect signal mode
- 🐌 Overcurrent at low speeds due to misconfigured boost or load jump
- 🌡️ Motor overtemp protection trips from thermistor failure or cooling problems
