Understanding the Indramat F406 Fault Code

Indramat, once a leader in motion control technology, was known for its high-quality products until it was acquired by Rexroth and later integrated into Bosch Rexroth operations, leading to the discontinuation of its original product line. The assortment of Indramat motion control products included motors, encoders, drive controllers, and power supplies, all designed to cater to a broad spectrum of industrial applications. Despite their cessation in manufacturing, Indramat products are lauded for their durability and outstanding performance and remain essential in many older motion control systems today.

Although new Indramat products are no longer available, refurbished units can still be obtained from various vendors.

Indramat products are known to display a range of error codes when issues arise. These codes are crucial for diagnosing problems, enabling either straightforward fixes within the facility or requiring the involvement of skilled technicians.

One such error code, the Indramat F406, is characterized as a "Phase switching without ready signal error." This issue is displayed on the drive controller’s H1 status panel, alternating between "F4" and "06."

Common Causes of the F406 Fault Code:

The F406 error can occur under two scenarios, both involving the SERCOS module:

1. The SERCOS master module attempts a phase change but doesn’t receive a ready signal from the corresponding drive controller.

2. There is a malfunction or defect within the SERCOS module itself.

FAQs:

1. What type of error code is the F406 fault code?

   - The F406 is classified among the F4XX series of F codes by Indramat, which are generally interface error codes. When such codes appear, the drive controller will opt for the best possible deceleration settings available.

2. Can the Indramat F406 fault code be fixed in-house?

   - Addressing the F406 fault code usually surpasses basic in-house troubleshooting capabilities due to its complexity. It typically demands the attention of technicians who are specifically trained to manage and resolve such intricate issues. Hence, professional assistance is advised for effectively handling this fault in your motion control systems.

Navigating these error codes and understanding their implications are essential steps in maintaining the continuous operation and performance of Indramat-powered systems.
