Drive Features and Use Case
This drive comes with an integrated brake switch, making it perfect for operations requiring quick deceleration of large loads. It’s an excellent fit for conveyors, fans, and process control systems where torque control and braking are critical.
Common VFD Faults We Repair
- 🛠️ Excessive DC Bus Voltage – May occur when decelerating heavy inertia loads.
- 🛠️ Low Voltage Dropouts – Often caused by unstable or missing supply phases.
- 🛠️ Motor Overcurrent – Linked to improper load profiles or sudden load spikes.
- 🛠️ Overheated Heatsink – Triggered by limited airflow or dense panel layout.
- 🛠️ Motor Stalls – Typically due to low current limits or boost setting issues.
- 🛠️ Brake Resistor Overload – Common with repetitive or high-torque stops.
- 🛠️ Brake Switch Trips – Resulting from intense deceleration demands or faults.
- 🛠️ Communication Loss – Timeout errors due to parameter misconfiguration.
- 🛠️ STO Board Failures – Safe Torque Off circuits are repairable in-house.
- 🛠️ Control/Power Card Errors – We resolve internal communication problems swiftly.
- 🛠️ Feedback Loop Errors – Encoder or wiring faults may trigger overspeed trips.
- 🛠️ Overcurrent at Low Speeds – Usually tied to boost values or torque profiles.
- 🛠️ 24V Power Fault – From output rail short or overload.
- 🛠️ Input Phase Failure – Inconsistent power supply or rectifier damage.
- 🛠️ IGBT Desaturation – A fast internal fault in the power bridge; common and repairable.
- 🛠️ Ripple Voltage High – Suggests missing input phase or failing capacitors.
- 🛠️ Brake Short Circuit – Typically traced to brake wiring or resistor configuration.
- 🛠️ Overspeed Fault – Linked to bad speed feedback or motor tuning errors.
- 🛠️ Analog Input Fault – Shorted sensor wires or wrong scaling on 4-20mA inputs.
- 🛠️ Boost-Related Current Faults – Due to aggressive torque profiles at low speeds.
- 🛠️ Motor Overtemperature – Often caused by blocked ventilation or sensor faults.
