Parker 690+0015/460/1BN | 11 kW / 15 HP VFD – 460V, Standard Enclosure

Fast Repairs or Same-Day Replacements

The Parker 690+0015/460/1BN is a 15 HP variable frequency drive built for 460V applications, housed in a durable NEMA 1 enclosure. It includes a factory-installed brake switch and no system board — making it ideal for standard automation use. Flexa Systems offers expert repair and quick supply options.

Typical Faults – All Repairable by Flexa

From power issues to logic faults, we restore these units fast. Here’s what we commonly resolve:

• Overvoltage on DC Bus: Often caused by regen energy, improper decel, or brake circuit mismatch.
• Undervoltage Detection: Power sag, weak input phases, or failing power supply stages.
• Current Spike Trip: Load faults, shorted outputs, or excessive ramp rates can trigger this.
• Overheat Shutoff: Drive disables output due to heatsink or ambient thermal rise.
• Motor Stall Fault: Motor fails to rotate under configured torque limits or loads.
• Braking Resistor Fault: Trip caused by external resistor overload or under-rated resistance.
• Internal Brake Switch Failure: Repeated decel cycles damage internal switching components.
• Communication Timeout: Loss of signal from HMI or PLC controller, usually recoverable.
• STO Trip: Safety loop error or wiring loss triggering Safe Torque Off condition.
• Internal Logic Fault (Code N): Drive logic fails handshake between control and gate driver boards.
• Feedback Loss or Overspeed: Encoder signal dropout or misconfiguration leads to speed-related faults.
• Excess Current Alarm: Load briefly draws beyond limit — from sudden torque spikes or tuning mismatch.
• Auxiliary 24V Rail Fault: Short or overload on IO circuit pulling down control voltage.
• Phase Loss Detection: Missing one power leg, either externally or inside the drive input stage.
• Desaturation Event: Instant protection against IGBT overcurrent — often repairable at power board level.
• DC Link Ripple Voltage Fault: Caused by capacitor failure or input waveform distortion.
• Brake Output Short: Short circuit in external resistor or drive output path detected.
• Motor Overspeed Trigger: Motor RPM exceeds configured max — usually due to encoder fault or instability.
• Analog Input Error: Sensor signal missing, out of range, or improperly scaled.
• Low-Speed Overload: High current drawn when motor is at zero speed — typically due to high boost or blocked load.
• Motor Temp Fault: Thermistor detects overheating — due to cooling issues or sensor damage.
