What Can Go Wrong? Here’s What We Fix

Parker 690+ drives are dependable — but like any industrial VFD, they can develop issues. We routinely repair the following:

• High Voltage Trip: Surges in the DC bus caused by abrupt stops, power issues, or improper braking setup.
• Low Voltage Alarms: Under-voltage trips linked to missing supply phases or weak incoming power.
• Overcurrent Faults: Current draw spikes due to shock loads, miswired motors, or internal shorts.
• Excessive Heat: Thermal shutdown from poor airflow, ambient heat, or failed heatsink components.
• Motor Stall Detection: The drive halts when it senses the motor isn’t rotating under expected load.
• Brake Resistor Overload: Dynamic braking circuitry overheating due to rapid decel rates.
• Brake Switch Stress: Drive tripping from overloaded or faulty internal braking switch.
• Communication Loss: HMI or controller disconnects triggering “Lost Comms” faults.
• Safe Torque Off Failure: STO board malfunctions — a common failure we repair with high reliability.
• Comm Code ‘n’ Errors: Internal data bus miscommunication between the control and power boards.
• Feedback Errors: Encoder or speed signal loss leading to drive inaccuracy or overspeed conditions.
• Current Limiting Trips: Exceeding stack current capacity due to process spikes or overloads.
• 24V Supply Issues: Low voltage detection on customer output, often caused by shorts or load surges.
• Phase Failure: One or more input phases missing — or damaged input stages inside the VFD.
• Desaturation (DESAT): Instantaneous overcurrent events usually tied to a failing power section.
• Ripple Voltage Faults: High DC ripple indicating poor rectification or unbalanced phase input.
• Brake Short Circuit: Short detected in external brake resistor wiring or inside the drive.
• Overspeed Detected: Drive flags speed exceeding safe limit — usually encoder or motor-related.
• Analog Input Failure: Misconfigured or damaged analog inputs, often from incorrect 4–20mA wiring.
• Low Speed Overcurrent: Motor pulls too much current while stationary — bad boost settings or faults.
• Motor Overtemp Warning: Internal temperature sensor alerts or thermistor failures.
