Understanding the KEB F6 Drive System

The KEB F6 Drive is engineered to provide precision control over industrial motors, allowing you to change the speed, control the position, and connect to other automation systems with ease. These drives are often utilized in places where precise motor management is critical such as conveyor belts, packaging machines, or elevators.

The F6 has a few variants, such as the 13.F6.K1D-YU4M which as an inverter size of 13 and a more compact design or the 15.F6.A32-3513 with an inverter size of 15 and is slightly larger. Each variant is designed with precision and quality in mind. A key feature of the F6 series is the brake control system, which ensures safe and reliable operation, especially in applications where precise stopping and holding are critical.

Common Error Codes and Their Meanings

The KEB F6 drive system utilizes a comprehensive error code system displayed in the ru01 exception state parameter. These errors include events like overcurrent, overvoltage, overheating, and communication issues. Each error has its own code and explanation to help technicians find the main cause of the problem quickly.

Here are some common faults:

• ERROR overcurrent PU (code 3): Indicates there's a short circuit or the power module is broken.
• ERROR over potential (code 5): This means the voltage in the DC link is too high.
• ERROR overload (code 7): This indicates there is too much power load on one of the modules.
• ERROR overheat (code 10): This means the power supply is too hot.

Procedure for Clearing Error Codes on the KEB F6 Drive

The following steps outline the typical procedure for clearing an error on the KEB F6 drive:

1. Error Code Identification: First, identify the specific error code displayed in the ru01 exception state parameter.
2. Fault Rectification: Subsequently, address the underlying cause of the error. For instance, in the event of an overcurrent fault (code 3), investigate potential short circuits or inspect the power module.
3. Error Reset: To clear the identified error, initiate the "fault reset" function. This function can be activated by setting Bit 7 of the control word, either through the drive settings interface or via the connected control system.
4. Automatic Fault Response: The F6 drive incorporates an automatic fault response functionality that attempts to rectify certain errors. This feature can be programmed for specific error types, such as undervoltage, using parameters like pn83 and pn84.
5. Power Cycle for Persistent Errors: Finally, some errors may necessitate a complete power cycle of the drive (turning it off and then on again) after the root cause of the fault has been resolved.

Important Considerations:

It is crucial to recognize that not all faults can be cleared using the same method. Therefore, it is advisable to consult with professionals at Wake Industrial to mitigate potential complications. They can categorize error responses into distinct groups, including:

• Immediate fault response (uncontrolled drive stop)
• Deceleration ramp to fault (controlled deceleration before shutdown)
• Quickstop (emergency stop)
• Disable operation (controlled deceleration while maintaining power)

For configurable errors, users have the flexibility to select the appropriate error response using the relevant pn parameters, allowing for application-specific adjustments.
