Engineering Brief

KEB Combivert F5 High-Power Inverter Architecture

The 19F5A1H-350F is a heavy-duty controlled frequency inverter within the KEB Combivert F5 series, engineered for demanding industrial motor management. Rated for 42 kVA apparent power and delivering up to 60A continuous output current, this unit controls 30 kW (40 HP) 3-phase asynchronous and synchronous AC/DC motors across standard 400V industrial grids.

Built with an internal GTR7 braking transistor and a forced-air cooling structure, the drive supports complex automation tasks via 8 freely programmable digital inputs and 2 programmable analog outputs.

Performance Parameters

Operational Applications & Diagnostic Capabilities

Target Machinery & Fault Surveillance

• Application Compatibility: Heavy industrial extruders, high-volume hydraulic pumps, industrial centrifuges, stone-cutting equipment, overhead crane hoisting units, and large supply fans.
• I/O Signal Routing: The 8 digital inputs facilitate multi-preset speed configurations, external trip interlocks, and direction swapping without auxiliary PLC relays. The 2 analog outputs handle real-time feedback logging (e.g., actual motor torque or operational frequency).
• Overcurrent Fault Monitoring: Microprocessor monitoring trips the output stage when phase currents cross the 90.0A peak limit, shielding the internal IGBT bridge from direct thermal destruction.
• DC Bus Voltage Protection: Onboard GTR7 brake chopper activates dynamic energy dissipation into external braking resistors during deceleration ramps to prevent overvoltage trips.
• Thermal Dissipation Watchdog: Temperature sensors on the main power heatsink trigger fan regulation and thermal warning bits in the drive software before junction over-temperature faults occur.

Global PLC Spare HUB's Insight

Engineering Field Observations

• The 19F5A1H-350F is a robust 30 kW motor control solution, offering a stable balance between raw power output and cabinet footprint (297x340x255 mm).
• Setting the carrier switching frequency to 4 kHz optimizes the power stage thermal performance, minimizing internal heat dissipation under continuous 60A loading.
• Integrating the GTR7 dynamic braking transistor directly into the power section eliminates the need for external chopper units in high-inertia stopping applications.
• Flexibility across 305...528V AC inputs makes this module suitable for deployment across fluctuating plant power grids without requiring step-down transformers.

Frequently Asked Questions (FAQ)

Technical Selection & Maintenance Guidance

Q: What size braking resistor should be installed with the GTR7 chopper on this 30kW inverter?
A: Select an external power resistor matching the minimum resistance specification defined in the F5 manual for Frame Size 19, sizing the wattage based on the duty cycle of your dynamic stopping profile.

Q: How do the 2 programmable analog outputs function during plant monitoring?
A: They can be scaled in parameter menus to transmit proportional 0-10V or 4-20mA signals representing variables like output frequency, motor current, or calculated shaft torque to remote meters or PLCs.

Q: What thermal clearances must be observed when installing this chassis inside an enclosure?
A: Leave a minimum vertical clearance of 150 mm above and below the heatsink air paths to prevent thermal recirculation around the 297x340x255 mm frame.

Q: Can this drive handle high-speed motor applications requiring output frequencies above 500 Hz?
A: Yes, it generates output frequencies up to 599 Hz, provided motor inductance limits and derating curves for higher switching frequencies are evaluated.

Q: How should line chokes be integrated when running on unstable 400V mains?
A: Installing a 3-phase line reactor on the 305...528V AC input terminal reduces line harmonics and absorbs voltage spikes, extending the service life of the DC bus capacitors.
