Decoding Rexroth Indradrive Fault Codes

Rexroth IndraDrives are at the heart of many manufacturing and industrial operations. However, encountering fault codes on your drive interface can be a daunting experience if you're not equipped with knowledge to interpret what these codes mean. We can simplify the process by decoding the most common fault codes, their potential causes, and solutions.

Here's an overview:

- F9xxx – Fatal System Errors

- F8xxx – Fatal Errors

- F7xxx – Safety Technology Errors

- F4xxx – Interface Errors

- F3xxx – Non-Fatal Safety Technology Errors

- F2xxx – Non fatal errors

- Exxxx – Warning Diagnostic Messages

Understanding Generic Fault Code Series

F9XXX Series

F9XXX codes represent serious issues that hinder the normal operation of the drive system and cannot be resolved through conventional means. When these errors arise, the drive's safety behaviors are deactivated, drive torque gets locked, and power is shut down post the display of a diagnostic message. A system reboot becomes necessary to regain functionality. Here are a few specific error examples:

  • F9001 – Error Internal Function Call: This error signifies a general software problem. To rectify, switch the drive OFF and then back ON; if the error persists, it may be necessary to replace the drive.

  • F9002 – Error Internal RTOS Function Call: This error is triggered by a software glitch. It's recommended to reach out to the manufacturer's Service or Customer Support team.

  • F9003 – Watchdog: This error results from a triggered watchdog timer. In such cases, contacting the Service team for a drive replacement is advisable.

F8XXX Series

F8XXX codes encapsulate fatal errors that can occur during initialization or operation. These errors, unable to be cleared ordinarily, necessitate a complete drive shutdown. When such errors are encountered, the drive's open-loop U/f control or closed-loop control cannot be guaranteed. Clearing these requires executing a cf, S-0-0099, C0500 Reset class 1 diagnostics error command, identifying and eliminating the root cause, and re-enabling the drive.

  • F8022 - Encoder Signals Incorrect: This error occurs when encoder signals fall out of hardware-supervised thresholds. Solutions involve inspecting and potentially replacing the encoder cable, or cleaning the encoder.
  • F8070 - +24 Volt DC Error: This arises when the control voltage supply falls outside tolerance limits. Check the supply cable and control voltage connector, and verify the power supply unit for rectification.


F7XXX series errors represent Safety Technology faults that cause automatic drive shutdown, putting the drive in safety-related standstill mode and turning off the output. To reset, specific procedures must be followed, which may include correction of any existing configuration errors. Here are some error examples:

F7010 – Safety Related Limited Increment Exceeded: This error occurs when position range values are exceeded in safety function. Clear the error by executing the S-0-0099, C0500 Reset command.

F7011 – Safety Related Limit Val., Exc. In Pos. Dir.: This error triggers when a certain limit is exceeded. Remedy involves executing the S-0-0099, C0500 Reset command to clear the error.

F7012 – Safety Related Limit Val., Exc. In Neg. Dir.: This error arises when a negative limit is exceeded. Resolution is similar, by running the S-0-0099, C0500 Reset command.

F4XXX Series

F4xxx codes highlight interface errors. These issues prevent normal NC reaction initiation and leave the drive torque-free post error reaction. Here are some specific examples:

F4001 – Double MST Failure Shutdown: This implies the drive didn't receive Master Synchronization Telegram (MST) in two continuous SERCOS cycles. You may need to inspect fiber optic connections or adjust SERCOS cycle times.

F4002 – Double MDT Failure Shutdown: It means the drive didn't receive Master Data Telegram (MDT) in two continuous field bus or SERCOS cycles. Start cyclic communication or inspect the fiber optic cable bus transmission line.

F4003 – Invalid Communication Phase Shutdown: It signifies an incorrect SERCOS master module communication phase. In such cases, it's best to consult the control unit's manufacturer.

F3XXX Series

F3XXX series errors signify non-fatal safety technology issues. These errors let the user specify the drive action through an appropriate parameter setting. Upon encountering these errors, the drive loses torque and power gets turned off. This is a large series of errors, and you can read a full list here. Some specific error examples:

F3111 - Reference Missing When Selecting Safety Related End Position: This happens when the acceleration threshold exceeds. To rectify, reset class 1 diagnostics and increase the value if necessary.

F3112 - Reference Missing When Selecting Safety Related End Position: Occurs without establishing safety related reference. Remedy involves reverting safety related position and resetting class 1 diagnostics.

F3117 - Plausibility Error of Actual Position Values: Triggered by implausible values for channels 1 and 2. Solution is to check parameterization and execute homing procedure command on channel 2.

F2XXX Series

F2XXX series encapsulates non-fatal errors, allowing for a variable and customized error response. They usually signify minor disruptions that can be fixed without substantial system interference. Here are three specific instances:

F2026 - Undervoltage in Power Section: Indicates a drop in DC bus voltage below the preset minimum value. Remedy includes reactivating the mains voltage or reducing power supply load.

F2816 - Softstart Fault Power Supply Unit: This error suggests a significant deviation in the DC bus voltage curve, indicative of a power section issue. Corrective actions encompass power section replacement or checking the mains voltage.

F2174 - Loss of Motor Encoder Reference: Occurs when the drive controller fails to establish a reference for encoder-related position data. Clearing the error and reestablishing position data reference is the recommended solution.

EXXXX Series

EXXXX codes encompass Warning Diagnostic Messages, which signal potential issues that might disrupt the system's optimal functioning. It's crucial to rectify these warning messages to prevent more severe complications. Here are a few specific examples:

E8260 – Torque/Force Command Value Limit Active: This warning is due to exceeding drive-related acceleration capabilities or incorrect torque/force limit values parameterization. You can resolve this by adjusting the preset velocity value, acceleration value, or torque/force limit values.

E8057 – Device Overload, Current Limit Active: This error indicates excessive thermal load on the drive controller, leading to continuous current limitation activation. Adjusting the drive controller to meet the motor or application requirements or optimizing the mechanical system can solve this issue.

E8034 – Emergency-Stop: Triggered by the drive controller's function to monitor its E-Stop input. Addressing the trigger cause, rectifying the configuration of digital outputs and inputs, or replacing the defective control section can mitigate this issue.
