What Is the Indramat F208 Fault Code?

Indramat motion control products are renowned for their durability, ruggedness, and long-lasting performance. Though the company no longer manufactures new products, Indramat drives and motors remain in use today across a wide range of industrial applications. Their modular design allows for straightforward maintenance and component replacement even decades after initial installation.

One commonly encountered diagnostic message is the F208 fault code, which helps operators identify a mismatch between the drive and motor configuration after a hardware change.

Understanding the F208 Fault Code

On ECODRIVE drive controllers, the F208 fault appears as F2 followed by 08 in a repeating sequence on the H1 status indicator. According to the Indramat manual, this code means:

“UL The motor type has changed.”

This fault typically occurs when you replace the servomotor and then power up the system for the first time with the new motor. The drive controller compares the motor type stored in its parameter file with the connected motor’s feedback memory. If there is a mismatch, the controller flags the F208 error to inform the operator.

What Happens Behind the Scenes?

Each Indramat motor contains feedback memory, which stores regulator settings for:

• Position control loop

• Velocity control loop

• Current control loop

When the F208 error is triggered, the controller identifies that the motor connected does not match the one previously programmed in the parameter file. Clearing the F208 code prompts the drive controller to overwrite the stored values with the new motor's default settings.

How to Clear the F208 Error Code

Clearing the F208 fault is a non-fatal, straightforward process that can be handled in house without professional assistance. The method depends on the type of motor you’ve installed:

 For MDD and MKD Motors:

• Simply press the S1 reset button on the front panel of the drive.

 For 2AD, 1MB, or ADF Motors:

• Use the C700 Basic Load Command to load default settings from the motor feedback memory.

Once the code is cleared, the controller will automatically load the appropriate motor data and resume normal operation.

FAQs

 Is F208 a critical fault?

No. F208 is a non-fatal error. It’s more of a notification than a critical fault, alerting the user to a change in hardware that needs to be acknowledged by the controller.

 What happens when the F208 code is cleared?

When you clear this code, the default control loop parameters from the motor are loaded into the drive controller. This action overwrites the existing controller settings.
