We Fix These Common Failures on This Model 🔍

• ⚠️ Overvoltage from oversized loads, regen energy with no brake resistor, or high supply input
• 🔋 Undervoltage issues from phase loss, line instability, or control board faults
• 🚨 Overcurrent from short circuits, load spikes, or poorly set boost parameters
• 🔥 Heatsink over-temp due to poor airflow or overheating cabinet conditions
• 🌀 Motor stall errors caused by excessive load or too-low current limit settings
• 💥 External brake resistor overload during abrupt or frequent stopping cycles
• 🧨 Internal brake switch trip from aggressive deceleration profiles
• 📡 Communication loss caused by bad cabling, improperly set COMMS timeout, or damaged ports
• 🛑 STO safety faults — often due to defective STO board components
• 🔁 Comms error between logic board and power section — usually solvable with firmware or board repairs
• 📉 Speed deviation errors from encoder feedback issues
• ⚡ Current limit exceeded during fast starts, torque bursts, or wrong ramp settings
• 🔌 24V output drop from overload or shorts in customer wiring
• ⚠️ Phase detection faults indicating missing phase or damaged internal components
• 💣 DESAT faults caused by blown IGBTs or shorted drive stages
• 📈 Ripple voltage instability from DC bus capacitor aging or input phase mismatch
• 🚧 Brake circuit faults due to shorted or improperly wired braking path
• 🚀 Overspeed conditions often from failed encoder feedback or configuration mismatch
• 🎚️ Analog input misreadings due to miswiring or mode conflict
• 🐌 Low-speed overcurrent from overboosting or failed motor wiring
• 🌡️ Motor overheating due to failed thermistor feedback or prolonged low-RPM usage
