Lenze EVF9326-ES Vector Frequency Inverter | Series 9300

Technical Specifications Breakdown

Key parameters for the EVF9326-ES are listed below for quick reference:

Industry Applications

Conveyor Systems and Material Handling

The inverter's 150% overload capacity for 60 secondsThe wide output frequency range (up to 600 Hz) allows for fine speed adjustment, enabling precise synchronization of multiple conveyor segments.

Pump and Fan Control

In HVAC and pumping applications, the EVF9326-ES can vary motor speed to match demand, reducing energy consumption. The -10 to 60°C operating range ensures reliable operation in typical machine rooms, while the IP20 protection class suits clean, enclosed environments.

High-Speed Machining

With an output frequency up to 600 Hz, this inverter can drive motors at high rotational speeds, making it suitable for specialized spindles or centrifuges. The LED display provides real-time status, allowing operators to monitor frequency and load conditions easily.

Installation & Setup Guidance

When installing the EVF9326-ES, ensure the control cabinet provides adequate ventilation to maintain the ambient temperature within the specified range. The panel mount design simplifies integration into existing control panels. Verify that the supply voltage matches the 400 to 480 Volts AC range and that the input is 3-phase. Connect the motor leads to the output terminals, ensuring the motor's rated voltage and frequency are within the inverter's output capabilities. Use the LED display to confirm proper parameter configuration before starting the motor.

Maintenance & Reliability

Regularly inspect the inverter for dust accumulation on heatsinks and fans, as this can impair cooling. Check all electrical connections for tightness and signs of corrosion. Because the device operates in temperatures up to 60°C, ensure that the cabinet temperature does not exceed this limit. Periodically verify that the overload protection settings are correctly configured to match the connected motor's characteristics.

Vector Frequency Inverter for Demanding Motor Control

The Lenze EVF9326-ES is a vector frequency inverter from the Series 9300, engineered for precise motor management in industrial environments. It converts a 3-phase input into a variable frequency output, enabling accurate speed and torque control for AC motors. With a power supply voltage range of 400 to 480 Volts AC and an output voltage up to 480 Volts AC, this inverter is suited for standard European and North American industrial power systems.

This model delivers a rated active power of 11 kilowatts (14.75 horsepower) and supports an output frequency range of 0 to 600 Hertz, making it versatile for both standard and high-speed applications. The device offers an overload capacity of 150% for 60 seconds, ensuring reliable performance under transient load conditions.

Compatibility & Integration

The EVF9326-ES is a standalone vector frequency inverter, designed to work with standard 3-phase AC induction motors. It accepts a 3-phase input and provides a variable frequency output. The LED display offers a simple interface for local monitoring and parameter adjustment. For integration into larger automation systems, consult the Lenze Series 9300 documentation for available communication options (not specified in the provided data).

Selection Guide & Purchasing Advice

When selecting a frequency inverter, consider the motor's power rating, voltage, and speed requirements. The EVF9326-ES, with 11 kW rated power and 14.75 HP capacity, is well-suited for medium-duty applications. Its IP20 protection class is appropriate for control cabinet installation. For applications requiring higher overload or wider temperature ranges, consult with AutoDCSTech to explore other options in the Lenze Series 9300 lineup.

Troubleshooting & Common Issues

• Motor does not start: Check that the input power is within the 400-480V AC range and that the 3-phase supply is present. Verify that the enable signal is active and that the frequency setpoint is not zero.
• Overload trips: If the inverter trips on overload, confirm that the motor load does not exceed the 150% for 60 seconds rating. Inspect the mechanical system for jams or excessive friction.
• Display shows error code: Refer to the Lenze Series 9300 manual for specific error code meanings. Common causes include overvoltage, undervoltage, or overcurrent. Ensure the supply voltage is stable and the motor connections are correct.
• High temperature warning: If the ambient temperature approaches 60°C, improve cabinet ventilation or reduce the inverter's load duty cycle.
