KEB 12F5A1D-3A0A F5 Combivert Axis Drive
Product Introduction
The KEB 12F5A1D-3A0A is a 3-phase drive from the F5 Combivert Axis Drive Series. It operates on 400 VAC input with a rated current of 13.3/10.6 A. The output power reaches 4 kW at 6.6 kVA with a switching frequency of 8 kHz. Additionally, this drive includes a 24V DC power supply for control circuits. You can use it for applications requiring precise temperature regulation and motor control.
Unlike standard drives, the KEB 12F5A1D-3A0A specializes in PID-based control. It accepts thermocouple and RTD sensor inputs directly. Therefore, this unit works well for ovens, dryers, and plastic processing machinery.
Technical Specifications
The KEB 12F5A1D-3A0A delivers an impressive 98% efficiency. Its temperature measurement resolution reaches 0.1°C across a range of -50°C to 150°C. The maximum heatsink temperature allowed is 90°C (194°F).
For outputs, this drive provides relay outputs and a 4-20 mA analog output. The 4-digit LED display shows status, temperature readings, and fault codes. Communication happens through RS485 Modbus RTU, which integrates easily with PLCs and HMIs.
Furthermore, the control type is PID (Proportional-Integral-Derivative). This closed-loop method maintains stable temperature or process variables without constant manual adjustment.
Mechanical and Mounting Information
The KEB 12F5A1D-3A0A uses a panel mount design. You can install it inside control cabinets with proper ventilation. The enclosure protects against dust and indirect splashes typical in factory environments.
Additionally, the F5 Series shares many common components across different models. This design simplifies spare parts management and maintenance planning.
Installation Guidelines
First, mount the KEB 12F5A1D-3A0A on a flat panel surface using four screws. Next, connect 400 VAC 3-phase power to the input terminals. Then, wire your thermocouple or RTD sensor to the designated analog input channels.
Meanwhile, connect the 24V DC control power separately. Use shielded twisted-pair cables for the RS485 Modbus RTU network. Finally, configure the PID parameters through the front 4-digit LED display or via Modbus commands. Always follow local electrical safety codes during installation.

Frequently Asked Questions (FAQ)
1. Can I use the KEB 12F5A1D-3A0A without a temperature sensor?
Yes, but you will lose PID temperature regulation. The drive still functions as a standard VFD.
2. Does this drive support single-phase input?
No, it requires 400 VAC three-phase power. Single-phase operation is not possible.
3. How do I set the PID target temperature?
Use the front 4-digit LED display and navigate to the PID setpoint parameter. Alternatively, send Modbus RTU commands.
4. What communication protocols does this drive support?
It supports RS485 Modbus RTU. No other protocols are available on this model.
5. What is the maximum switching frequency?
The KEB 12F5A1D-3A0A runs at 8 kHz switching frequency by default.
