Understanding Heat-Related Indramat Errors

Excessive heating in an Indramat servo system is a significant concern, often signaling potential heat-related problems and the risk of overheating. Generally, an Indramat component will display a warning code as a preliminary alert when it starts to overheat. If the temperature issue is not resolved promptly, the component might shut down automatically due to excessive heat.

Taking preventive measures against heat-related issues is more effective than addressing them after they occur. Regular maintenance and careful monitoring are key. For instance, it's recommended to check the fan bi-monthly and consider replacing it every ten years.

Typical Heat-Related Error Codes

Several heat-related error codes frequently occur within Indramat servo systems. Some common ones include:

- E250 – Heatsink Overtemperature Warning

- E251 – Motor Overtemperature Warning

- E252 – Bleeder Overtemperature Warning

- F218 – Heatsink Overtemperature Shutdown

- E219 – Motor Overtemperature Shutdown

- E220 – Bleeder Overtemperature Shutdown

FAQs

What is the "box fan" method for addressing heat-related errors?

Often seen as an economical fix, the "box fan" method involves using an external box fan to cool the servo system. This is usually a makeshift solution when addressing a failed or broken fan inside the cabinet without professionally repairing it. However, it's important to acknowledge the limitations and potential risks of this approach. Not only does it fail to ensure proper cooling, but it can also lead to further damage. Using a box fan with an open cabinet door can adversely affect the internal drive and might lead to the need for a drive replacement. Hence, it's crucial to thoroughly evaluate and repair the internal fan's condition when dealing with a malfunctioning cabinet.

What are common causes of heat-related errors in Indramat systems?

A widespread issue causing heat-related errors in Indramat systems is improper practices such as leaving control cabinet doors open. This is mistakenly believed to help in cooling the system but can instead allow dirt accumulation and condensation on electronic components, exacerbating overheating. Other factors include a faulty control cabinet, operation outside the recommended environmental conditions, high ambient temperatures in the plant, and damaged or ineffective fans and blowers. Overheating can result from any combination of these issues.
