• Enclosure: Chassis (IP20)
• Braking: Brake power switch installed
• System Board: Installed

🛠️ Most Common Faults We Can Help You With

• Overvoltage: Caused by rapid deceleration or high supply voltages — we’ll repair the circuitry and check the braking chain.
• Undervoltage: Low or missing supply phases, faulty rectifier section — we troubleshoot and resolve it.
• Overcurrent: Detected during acceleration/deceleration or due to shorted windings — our bench test can pinpoint the issue.
• Heatsink Overheat: Poor airflow or faulty fans — we clean, cool, and replace parts as needed.
• Stalled Motor: Motor not turning due to excessive load or wrong configuration — our tuning can fix it.
• Brake Resistor Trip: Happens when stopping heavy loads — we validate resistor sizing and replace failed components.
• Brake Switch Failure: Internal switch damage due to excessive braking cycles — we service or replace.
• Communication Timeout: Short comms timeout settings or board issues — our diagnostics will verify the root cause.
• STO Fault: Safety Torque Off trip — we can repair or replace the STO board reliably.
• Comm Error Code N: Control and power stage communication breakdown — common and fixable in our lab.
• Speed Feedback Error: Error due to encoder or feedback loss — we diagnose encoder and scaling setup.
• Current Limit Trip: Triggers under shock loads — we test motor load response and drive configuration.
• 24V Failure: Output voltage dropped — typically shorted external wiring or internal failure.
• Phase Loss: Missing input phases or blown fuses — our repair includes full supply validation.
• DESAT Trip: Instantaneous current surge — power stage components usually to blame, and we handle them all.
• Ripple DC Voltage: Ripple too high — we check capacitors and missing phase inputs.
• Brake Short Circuit: Excessive braking current — we confirm circuit integrity.
• Overspeed: Drive exceeds setpoint — encoder or feedback tuning needed, which we perform.
• Analog Input Error: Incorrect 4–20mA setup or wiring — we check and reconfigure cleanly.
• Low-Speed Overcurrent: Boosts too high or motor under too much load at low speed — fully tunable.
• Motor Overtemperature: Caused by thermistor faults or overload — we test sensors and settings thoroughly.
