Parker 690+0100/460/CNN | 100 HP 460V VFD
The Parker 690+0100/460/CNN is a robust variable frequency drive designed for heavy-duty industrial applications requiring 100 HP and a reliable 460V input. This specific model features an open chassis format with no braking circuitry and no system board installed, making it ideal for custom applications where external control and braking systems are managed separately.
- Power Rating: 100 HP (Frame F)
- Input Voltage: 460V AC ±10%
- Enclosure: Chassis (IP20)
- Braking Option: None (N – Not Fitted)
- System Board: Not Included (N)
Drive Configuration Overview
Engineered for flexibility, the CNN configuration offers a streamlined build with no onboard braking system or system controller, giving integrators complete control over external modules. Whether you’re replacing a failed unit or scaling your system, this model offers solid baseline functionality.
Most Frequent Faults Resolved by Flexa Systems
- ⚠️ DC Bus Overvoltage – Often caused by rapid deceleration or improper resistor configuration.
- ⚠️ Undervoltage Conditions – Traced to unstable power inputs or loss of supply phases.
- ⚠️ Overcurrent Faults – Can result from shock loads or short circuits in motor leads.
- ⚠️ Heatsink Temperature Overload – Poor airflow or high ambient conditions often to blame.
- ⚠️ Motor Stall Detection – Typically due to misconfigured current limits or excessive load.
- ⚠️ Brake Resistor Overload – Occurs during repeated emergency stops or heavy load inertia.
- ⚠️ Brake Switch Fault – Signs of wear from heavy deceleration cycles or setup mismatches.
- ⚠️ Communication Timeout – COMMS parameters may be misconfigured or require reset.
- ⚠️ STO (Safe Torque Off) Failure – A common hardware issue we fix with confidence.
- ⚠️ Internal COMMS Errors – Disruptions between logic and power sections; often fixable via firmware rework.
- ⚠️ Speed Feedback Error – Can be due to faulty encoders or wiring issues.
- ⚠️ Current Limit Tripped – When the motor draws excessive current during load spikes.
- ⚠️ 24V Control Failure – Short circuits or excessive load on the output rail.
- ⚠️ Phase Loss – Missing power input phases or internal bridge faults.
- ⚠️ Desaturation Events – High-speed faults in the IGBT section, often power side related.
- ⚠️ DC Ripple Issues – Indication of input imbalances or capacitor degradation.
- ⚠️ Brake Short Circuit – Triggers when brake circuitry is overloaded or miswired.
- ⚠️ Overspeed Faults – Often caused by faulty feedback devices or control instability.
- ⚠️ Analog Input Errors – Bad scaling, sensor failure, or short circuits in external inputs.
- ⚠️ Low-Speed Overcurrent – Indicates possible motor tuning or boost setting issues.
- ⚠️ Motor Overtemperature – Triggered by load misalignment or thermistor circuit breaks.
