We Repair These Common Faults on This Unit 🔧

• ⚡ Overvoltage during deceleration due to regen energy buildup or missing braking resistor
• 🔋 Undervoltage caused by low power supply, missing phase, or internal PSU fault
• 🚨 Overcurrent when torque spikes, motor wiring faults, or improper boost is applied
• 🌡️ Heatsink temperature trips due to cooling fan issues or poor airflow in enclosure
• 🛑 Motor stalling — generally a result of excessive load or misconfigured stall protection
• 🔥 Brake resistor overload — especially in high-inertia applications or with undersized braking setup
• 💥 Brake switch trip due to repeated heavy braking or excessive thermal stress
• 📡 Lost communications — often tied to COMMS parameter misconfig or damaged cabling
• 🛑 STO is not present, but drive may still shut down from I/O safety loop issues
• 🔄 Internal logic/power board desynchronization from firmware or hardware failure
• 🎯 Speed feedback alarms — caused by encoder signal drop or parameter mismatch
• ⚠️ Current limit exceeded when motor ramp or torque curve is too aggressive
• 🔌 24V output undervoltage caused by overloaded external circuits or shorted terminals
• ⚠️ Phase loss alarms due to fuse failure, loose wiring, or internal board damage
• 💣 DESAT fault — usually blown IGBT or power stage fault, often seen in high-torque operations
• 🔄 VDC ripple alarms — typically caused by degraded DC link capacitors or phase input issues
• 🧨 Brake resistor circuit trips due to short circuit or overload current
• 🚀 Overspeed feedback caused by encoder issues or unstable control loop
• 📏 Analog input misreadings — typically sensor signal out-of-range or shorted cable
• 🐌 Low-speed overcurrent — common when boost is set too high at zero frequency
• 🌡️ Motor overheating due to improper ventilation, failed thermistor, or overdriven motor
