Failures We Routinely Repair

Here’s a complete breakdown of all issues we see — and solve — with this drive type:

• DC Bus Overvoltage: Regeneration surge or incorrect braking resistor sizing can push the voltage too high.
• Input Undervoltage: Voltage dips from incoming power or supply instability trigger protection shutdowns.
• Overcurrent Events: Start-up overloads, phase imbalance, or short circuits often lead to current spikes.
• Overheating: Poor ventilation or blocked airflow raises drive temperature beyond safe limits.
• Stalled Motor Trigger: When torque demand exceeds drive output or motor isn’t rotating as expected.
• Braking Resistor Fault: Caused by frequent decel cycles or damaged external brake resistor.
• Brake Switch Failures: Internal power stage for braking overheats or wears out under load.
• Communication Timeouts: Control or display panel loses handshake with the drive.
• Safe Torque Off Error: Safety signal lost or STO board failure — very common, quickly fixable.
• Control Bus Error (Code N): Disruption between logic and power stage causes internal comms fault.
• Speed Feedback Problems: Encoder faults, wiring issues, or invalid feedback signals cause overspeed or instability.
• Current Limit Violation: Overload scenario where motor demand exceeds drive capability.
• Aux 24V Output Drop: Fault on the low-voltage output rail due to shorts or excess draw.
• Phase Loss Fault: Missing one or more input legs — can be internal rectifier or external issue.
• DESAT Trip: Instant power stage trip due to transistor protection kicking in from overcurrent.
• Ripple Voltage Exceeded: Poor filtering or power imbalance leads to unstable DC voltage.
• Brake Short Detection: Overcurrent within dynamic brake output — internal or wiring related.
• Speed Overshoot Trip: Drive exceeds setpoint limits due to feedback instability or tuning.
• Analog Signal Error: Bad input on 4–20mA or 0–10V channel due to wiring or sensor failure.
• Overcurrent at Zero Speed: Happens when boost levels are wrong or motor insulation is failing.
• Motor Overtemperature: Either from continuous overload or damaged thermistor/sensor input.
