Parker 690+0150/460/CBS | 150 HP 460V VFD

The Parker 690+0150/460/CBS is a top-tier 150 HP AC drive that comes with a chassis enclosure, integrated braking switch, and a built-in system control board. Designed for demanding automation setups, this configuration offers both high braking capability and communication/control flexibility through its system board.

• Horsepower: 150 HP (Frame F)
• Voltage Input: 460V AC ±10%
• Enclosure: Chassis Mount (IP20)
• Braking Circuit: Brake switch included (B)
• System Board: Installed (S)

Why This Model?

This specific CBS configuration is tailored for advanced control environments. The presence of a system board enables fieldbus communication and flexible I/O mapping, while the brake switch allows it to decelerate heavy loads safely and repeatedly. Perfect for conveyor lines, cranes, presses, and high-speed equipment.

Typical Faults We Resolve

• ⚠️ High DC Link Voltage – Often caused by aggressive deceleration without proper resistor sizing.
• ⚠️ Input Power Drops – Detected when voltage supply phases drop or dip below spec.
• ⚠️ Excess Motor Amperage – Shock loads or faulty tuning can result in overcurrent faults.
• ⚠️ Drive Overheating – Result of blocked airflow, compact cabinet layouts, or ambient heat.
• ⚠️ Motor Not Starting – May relate to system board misconfiguration or torque limit settings.
• ⚠️ Brake Resistor Trip – When brake energy exceeds design rating or resistor is undersized.
• ⚠️ Brake Switch Fault – Caused by fast load stops or excessive heat buildup.
• ⚠️ COMMS Timeout – The system board may lose handshake if network parameters are off.
• ⚠️ STO Malfunction – Common if Safe Torque Off wiring is open or STO board is faulty.
• ⚠️ Control ↔ Power Desync – Internal communication issues; often fixed by firmware updates or board-level repairs.
• ⚠️ Encoder Overspeed – Feedback loop instability or noise can trigger this.
• ⚠️ Instant Current Spike – When current exceeds limits during rapid torque changes.
• ⚠️ 24V Dropout – Caused by overloaded accessories or shorted I/O modules.
• ⚠️ Phase Loss – One or more supply lines are open or weak.
• ⚠️ IGBT Overcurrent (DESAT) – Indicates internal power section failure.
• ⚠️ Ripple Voltage Detected – Suggests capacitor issues or input imbalance.
• ⚠️ Brake Short Circuit – Often related to wiring or damaged resistor components.
• ⚠️ Overspeed Detection – Control system might see noise or invalid RPM readings.
• ⚠️ Analog Input Error – Mismatched signal types or sensor failure.
• ⚠️ Boost Overdraw – Occurs at low speeds if torque boost is too aggressive.
• ⚠️ Motor Overtemperature – Likely caused by airflow restriction, load issues, or failed thermistor.
