KEB 09F5C1B-3A0A 1.5kW Frequency Inverter – F5 Series

KEB 09F5C1B-3A0A Frequency Inverter for Precision Motor Control

Product Introduction

The KEB Combivert F5 frequency inverter, model 09F5C1B-3A0A, delivers 1.5 kW of power for demanding industrial applications. It operates on a 3-phase 400V power supply at 50/60 Hz. The input current rating stands at 4.1 Amps, while the maximum current reaches 8.9 Amps for handling overload conditions. Output frequency ranges from 0 to 800 Hz, and output voltage spans 0 to 480V AC. This drive complies with EN 61800-2 and EN 61800-5-1 for product safety and performance.

Technical Specifications – Core Electrical Parameters

The 09F5C1B-3A0A features a switching frequency adjustable between 8 kHz and 16 kHz. This flexibility allows users to balance between low motor noise and reduced switching losses. For electromagnetic compatibility, the drive follows EN 61800-3 for emitted interference, minimizing disruption to nearby equipment. Short-circuit monitoring and earth fault monitoring come standard, enhancing operational safety per industry requirements.

Feedback and Encoder Support

One standout feature of the 09F5C1B-3A0A is its broad encoder compatibility. It supports:

• Resolver feedback

• Incremental encoder feedback

• Sin/Cos encoder feedback

• Absolute encoder feedback

Such versatility makes this drive suitable for precision positioning applications. Furthermore, a potential-free operator connection is available. Serial interfaces are also included, enabling seamless integration into complex automation networks.

Environmental and Mechanical Dimensions

The KEB 09F5C1B-3A0A carries an IP20 enclosure rating. This protects against solid objects larger than 12mm but not against water. Therefore, install it inside a clean, dry control cabinet. The operating temperature range spans -10°C to +45°C. Storage temperatures may range from -25°C to +70°C. Physical dimensions are as follows:

• Height: 22 cm (8.6 inches)

• Width: 9 cm (3.5 inches)

• Length: 16 cm (6.2 inches)

• Weight: 2.0 kg (4.4 lbs)

Installation Guidance for the KEB 09F5C1B-3A0A

First, mount the 09F5C1B-3A0A vertically on a non-flammable surface. Ensure at least 100 mm of free space above and below for airflow. Next, connect the 3-phase 400V AC input to terminals L1, L2, L3. Use appropriate fusing rated for 4.1A nominal input current. Then, wire the motor to output terminals U, V, W. For feedback devices, connect your encoder (resolver, incremental, Sin/Cos, or absolute) to the dedicated feedback port. Finally, power up the unit and configure parameters via the serial interface or optional operator panel.

Frequently Asked Questions (FAQ)

1. Can the KEB 09F5C1B-3A0A run without an encoder?
Yes. The drive supports sensorless operation. However, for closed-loop precision, you can add resolver, incremental, Sin/Cos, or absolute encoder feedback.

2. What is the difference between the 07F5C1B and this 09F5C1B model?
The 09F5C1B-3A0A offers 1.5 kW power and 8.9A maximum current. The 07F5 series typically provides 0.75 kW. Choose based on your load requirements.

3. Does this drive include an EMC filter?
The 09F5C1B-3A0A follows EN 61800-3 for emitted interference. An internal EMC filter is present. For stricter environments, an external harmonic filter may be added.

4. How do I change the switching frequency?
Access the parameter menu via the serial interface or an optional keypad. Adjust the switching frequency parameter between 8 kHz and 16 kHz. Higher frequencies reduce motor noise but increase heat.

5. Is the IP20 rating safe for washdown areas?
No. IP20 offers no water protection. Install the 09F5C1B-3A0A inside an IP54 or higher rated enclosure if moisture or dust is present.
