KEB 17F5A1G-350A F5 Drive 18.5 kW 400V 75A

KEB 17F5A1G-350A 18.5 kW F5 Combivert Axis Drive

Product Introduction

The KEB 17F5A1G-350A delivers powerful motor control for heavy industrial applications. This axis drive belongs to the respected F5 Combivert series. It operates on three-phase 400V systems with an 18.5 kW power rating. For peak demands, the unit supplies up to 75A (Imax). Furthermore, the 17.F5.C1G-350A includes field-oriented control for precise torque and speed regulation. You will also benefit from optional KEB-SMM sensorless motor management. Consequently, this drive reduces the need for external feedback devices while maintaining high performance.

Technical Specifications

The 17F5A1G-350A offers robust electrical characteristics for demanding machines. Below are the key parameters:

• Voltage: 3-phase 400V

• Input Current (In): 42 A

• Max Current (Imax): 75 A

• Power Rating: 18.5 kW

• Switching Frequency: 4/16 kHz (configurable)

• Protection Class: IP20 / VBG 4

• Interference Emission Standard: EN 61800-3

• Product Standards: EN 61800-2, EN 61800-5-1

Moreover, the drive meets strict EMC requirements for industrial environments. Its C1 EMC part number indicates suitability for residential and light industrial settings as well. Therefore, you can install the KEB 17.F5.C1G-350A near sensitive control equipment.

Environmental & Operating Parameters

This drive handles tough conditions with ease. Its operating temperature ranges from -10°C to 45°C. Storage temperature extends from -25°C to 70°C. Additionally, the IP20 enclosure protects against fingers and small objects above 12mm. However, this drive is not waterproof or dust-tight. For indoor use only, install it inside a control cabinet. Furthermore, the VBG 4 compliance adds mechanical safety for German industrial accident prevention standards.

Advanced Control Features

The 17F5A1G-350A excels in precision motor control. First, field-oriented control (FOC) provides decoupled control of torque and flux. This results in fast response and high efficiency across the speed range. Second, synchronous motor control allows operation with permanent magnet motors. Third, optional KEB-SMM (sensorless motor management) eliminates the need for encoders or resolvers. Meanwhile, the drive automatically tunes itself to your motor's characteristics. As a result, you get near-servo performance without the cost of feedback devices.

I/O & Connectivity Options

The 17.F5.C1G-350A offers flexible input configurations. It includes 8 programmable digital inputs for various command signals. You can assign these for start/stop, fault reset, speed presets, or safety functions. Additionally, the drive provides 2 analog inputs with multiple ranges:

• 0 to 10V

• ±10V

• 0 to 20 mA

• 4 to 20 mA

Specifically, these analog inputs accept both voltage and current signals. Therefore, you can connect standard PLC outputs, potentiometers, or pressure transducers directly. For outputs, refer to the drive manual for analog and relay configurations.

Installation Guidelines

Installing the KEB 17F5A1G-350A requires careful planning. First, mount the drive vertically on a flat, non-flammable surface. Maintain at least 100 mm clearance above and below for cooling air. Next, connect the three-phase input to L1, L2, and L3 terminals. Use copper wires rated for 75°C minimum. For 42A input, 10 mm² (8 AWG) is recommended. Then attach the motor leads to U, V, and W terminals. For switching frequencies above 4 kHz, keep motor cable lengths under 30 meters. Finally, program the parameters using the keypad or KEB software. Always verify earth grounding before power-up.

Safety & Protection Features

The 14F5C1D-380A includes multiple protection mechanisms. First, short circuit monitoring protects against phase-to-phase faults. Second, overtemperature protection shuts down the drive if internal temperatures exceed limits. Third, the IP20 enclosure prevents accidental contact with live parts. Furthermore, the VBG 4 compliance adds mechanical safety for industrial environments. For maximum safety, install an external circuit breaker rated for 50A before the drive.

Typical Applications

This drive suits many heavy-duty industrial machines. Specifically, it works well for:

• Extruders and injection molding machines

• Large conveyors and material handling systems

• Centrifuges and mixers

• Winders and unwinders

• Pumps and fans above 15 kW

Additionally, the KEB 17F5A1G-350A performs excellently in crane and hoist applications. Its field-oriented control provides smooth acceleration and precise load holding.

Frequently Asked Questions (FAQ)

1. Does the KEB 17F5A1G-350A require an external encoder?
No, with KEB-SMM sensorless motor management, external encoders are optional. However, you can add one for even higher precision.

2. What is the difference between 4 kHz and 16 kHz switching frequency?
4 kHz reduces switching losses and allows longer motor cables. 16 kHz reduces audible motor noise but may require output filters for long cables.

3. Can the 17.F5.C1G-350A run a 230V motor?
No, this drive outputs 400V only. A step-down transformer or different drive model would be needed for 230V motors.

4. How do I enable sensorless motor management?
Set parameter Pn.07 to 2 for KEB-SMM mode. Then perform an auto-tuning routine with your motor disconnected from the load.

5. What is the maximum motor cable length for this drive?
At 4 kHz, up to 100 meters of shielded cable is allowed. At 16 kHz, reduce length to 30 meters maximum to avoid reflections.
