How to Resolve Indramat Fault Codes

Indramat motion control systems are renowned for their reliability, precision, and long lifespan. Designed to deliver high performance under rigorous industrial conditions, these drives, motors, and power supplies rarely fail when operated within the manufacturer’s specifications. However, like any piece of equipment, wear and tear over time can lead to fault codes being displayed on the system.

These fault codes, which appear on the H1 status display or controller interface, serve as diagnostic indicators to help you understand the nature of the issue. While some can be resolved easily in house, others require professional repair or part replacement.

Understanding Indramat Fault Codes

Each Indramat product whether a drive controller, servo amplifier, power supply, or motor has its own catalog of error codes. These codes are documented in the original product manuals and help users identify the problem quickly. Many of these issues can be resolved by simply pressing the S1 reset button or reloading parameters, while others signal more complex problems requiring service or part replacement.

Common Indramat Fault Codes and Their Fixes

Here are some frequently encountered Indramat fault codes and suggested steps for resolution:

F208 – UL (Motor Type Changed)

This fault code appears when a new motor is powered up for the first time. It signals a change in the stored motor parameters.
Fix: Press the S1 button or execute the C700 Basic Load command to initialize the drive with default parameters.

F209 – PL (Load Parameter Default Values)

Triggered when a different firmware version is used that’s incompatible with existing parameters.
Fix: Run the load basic parameters command or press the S1 reset button to clear the fault.

F218 – Amplifier Overtemperature Shutdown

This error indicates the heatsink has exceeded its safe temperature threshold, causing the amplifier to shut down to prevent damage.
Fix:

• Ensure adequate ventilation

• Clean the heatsink

• Lower the ambient temperature

• Replace the blower fan if defective

F221 – Motor Temperature Surveillance Defective

Generated when the motor temperature monitoring circuit fails due to broken wires or short circuits.
Fix:

• Inspect and repair the motor’s temperature monitoring wiring

• Check for loose or faulty connections

F248 – Low Battery Voltage

A rare error indicating the internal battery is running low typically occurs after 10 years of use.
Fix: Replace the servo drive battery within two weeks to avoid memory loss.

FAQs

 How are Indramat fault codes documented?

Indramat fault codes are listed in the user manual for each product series. Each code includes:

• A code definition

• Possible causes

• Recommended actions
  These are presented in logical order, allowing users to troubleshoot from the most likely to the least likely cause.

 Can all fault codes be resolved in-house?

Some codes such as F208 or F209 can be cleared by pressing the S1 button or reloading firmware parameters. Others, such as F221 or F248, may involve component-level diagnostics or replacements and should be addressed by a trained technician.
