Repairable Faults We Frequently Solve 🛠️

• ⚡ Overvoltage conditions from regen loads or braking misconfigurations
• 🔋 Undervoltage trips caused by low input supply or missing phase
• 🚨 Overcurrent shutdowns — typical causes include motor cable shorts or load surges
• 🌡️ Heatsink temperature alarms from blocked ventilation or cooling fan failure
• ⛔ Stall detection trips due to excessive mechanical load or improper torque limits
• 🧨 No brake switch present — deceleration faults may appear during abrupt stops
• 📡 Communication timeout — COMMS port fault or short watchdog settings
• 🛑 STO safety faults — often related to STO signal integrity or failed board input
• 🔁 Controller to power section desync — common after firmware corruption or internal bus damage
• 🎯 Encoder/speed feedback errors — resulting from signal loss or configuration mismatch
• ⚠️ Current limit exceeded under sharp acceleration or torque shock
• 🔌 24V output line sag from customer terminal short circuits
• ⚡ Phase detection faults caused by missing leg, fuse failure, or internal trace issue
• 💥 Instantaneous overcurrent (DESAT) from failed IGBTs or control section issues
• 🔄 DC ripple alarms from aged capacitor banks or power phase imbalance
• 🛠️ Analog input misreadings due to signal overrange or improper sensor wiring
• 🐌 Overcurrent at low frequency from boost overshoot or poor motor tuning
• 🌡️ Motor thermal faults triggered by open thermistor or blocked cooling path
