Understanding the Indramat F220 Fault Code

Indramat has built a reputable legacy in motion control systems with a comprehensive lineup that includes drive controllers, motors, encoders, and power supplies, offered in multiple configurations. Despite ceasing operations over two decades ago, the robustness, long-lasting nature, and superior performance of their products remain valuable in current technological applications.

Detailed in the drive controller's user manual are various error codes along with their causes and the suggested remedial actions. Prominently, the Indramat F220 fault code stands out. This non-fatal error leads to an automatic drive shutdown as a safeguard, similar to other errors in the F series. Implementing consistent maintenance and climate control is a proven strategy to lessen or prevent F220 and other related errors.

Specifically, the F220 fault is associated with "Bleeder overload shutdown" due to overheating, as noted in the manual. This error displays alternately as "F2" and "20" on the H1 status display.

This overheating typically occurs when the motor generates regenerative energy that surpasses the bleeder or braking resistor's capacity, thus exceeding safe operational limits. In such instances, the drive takes preemptive action by shutting down to protect the bleeder from damage due to overheating.

Steps to Fix the F220 Fault Code

Addressing the F220 fault involves several steps:

- Lowering the acceleration setting if the input power is excessively high.

- Reducing the velocity if the energy output is too high.

- Ensuring that the drive installation is correct and conforms with its designed specifications.

- Installing an additional bleeder module if required.

Frequently Asked Questions

1. What proactive measures can prevent the F220 fault code?

   An early warning code is usually displayed on the H1 screen before any shutdown triggered by the F220 fault. Promptly responding to these warning signs by making the necessary adjustments and conducting timely repairs can prevent this fault from occurring.

2. Is it possible to manage the resolution of the F220 fault code internally?

   While certain tasks like altering acceleration and velocity levels or adding a bleeder module might require technical knowledge or professional help, checking that the installation of the drive is accurate can definitely be carried out internally.

Adhering to these measures ensures that operators can maintain seamless operation of their Indramat systems, effectively minimizing disruptions caused by faults such as the F220.
