Faults and Warning Messages
Jump to a section on this page:
A warning, generally a notification, that is not critical and does not require the machine to immediately shut off. A fault, generally a notification, is a critical system failure that stops machine operation. The severity of the fault depends on which system-stop mechanism is used.
Faults and warnings follow the same pattern and are identified by a four digit code:
G G X X
where GG is a two digit group code and XX is a two digit ID. All faults and warnings are grouped together to easily identify the part of the system having trouble.
| Group | Group # |
|---|---|
| 10 | System |
| 11 | File |
| 15 | Hardware |
| 20 | Power |
| 25 | Temperature |
| 30 | Software |
| 4# | Feedback (# indicates the feedback number) |
| 50 | Motor |
| 55 | Wake and Shake |
| 60 | Motion |
| 70 | Fieldbus |
| 90 | Safety |
Retrieving Fault and Warning Information
Faults are retrieved on a per-axis basis with: AXIS#.FAULTS, where # is the axis number. Similarly, retrieve per-axis warnings with AXIS#.WARNINGS.
DRV.FAULTS returns faults across all axes, with the format X-#### where X is the axis number and #### is the four digit fault code. DRV.WARNING provides warnings across all axes with a similar format.
Feedback faults are reported with axis faults if the feedback is configured as a feedback source for the axis (e.g. AXIS#.IL.FBSOURCE, AXIS#.VL.FBSOURCE , AXIS#.PL.FBSOURCE ). If a feedback is not a feedback source for an axis, its faults are read with FB#.FAULTS where # is the feedback number.
Clearing Faults and Warnings
Once fault conditions are corrected, clear faults on an axis using AXIS#.CLRFAULTS . To clear faults on all axes with a single command, use DRV.CLRFAULTS .
The action table can also be used to clear faults. Action task 12: Clear Faults can be configured to trigger on edge conditions of the action sources. The action task ID selects the axis on which to clear faults.
The hardware enable input can also be used to clear faults. If AXIS#.HWEN.MODE is 0, faults for the axis are cleared on the rising edge of the hardware enable signal.
Fault History
Faults are logged to flash memory for convenience and debugging. To retrieve the last 50 faults with timestamps, use the keyword DRV.FAULTHIST.
To retrieve a more extensive history of faults, use DRV.FAULTHIST/all.
Fault Reaction
The drive’s reaction to a fault is determined by the nature and severity of the fault and the ability of the drive to control motion to zero speed. There are three supported fault reactions:
- Perform a controlled stop to decelerate to zero speed, using the controlled stop configuration for the axis. See Controlled Stop.
- Perform dynamic braking to decelerate the axis to zero speed. See Dynamic Braking.
- Disable the power stage for the axis that allows the connected motor to coast to zero speed.
Fault Table
A list of all possible faults and warnings can be found by using DRV.FAULTLIST.

For example, homing modes 3, 6, 10 and 11 require the feedback to provide a Z/index pulse and not all feedbacks provide this signal. If the homing move is started then it may run continuously because it is missing a signal from the feedback. | Select a different homing mode or change the feedback being used. |
| W6026 | Current homing mode requires (see AXIS#.HOME.IPEAK) to be set by user. | The homing mode selected requires that AXIS#.HOME.IPEAK is set to non-zero. | Set AXIS#.HOME.IPEAK to a value non-zero. |
| W6027 | Current command saturated. | AXIS#.IL.CMD has exceeded AXIS#.IL.LIMITP or AXIS#.IL.LIMITN . | Increase current limits (AXIS#.IL.LIMITP or AXIS#.IL.LIMITN ) or reduce load by decreasing trajectory acceleration/velocity. |
| W6028 | Gear feedback source is invalid. | The feedback selected as the gearing source is uninitialized or assigned to the same feedback being used as the commutation, velocity, or position feedback source. | Verify (see AXIS#.GEAR.FBSOURCE) is not 0 and does not match the feedback being used for AXIS#.IL/VL/PL.FBSOURCE. |
| W6029 | Gantry Position error higher than warning threshold. | GANTRY.PL.ERR exceeded GANTRY.PL.ERRWTHRESH. | Increase warning threshold, fix mechanical linkage, improve tuning or remove disturbances. |
| W6030 | Target position was overshot due to invalid Motion Task activation. | The drive cannot decelerate from its current speed to reach the end point of the second Motion Task without moving past it. Increase the deceleration rate in the move or trigger the move earlier.
Note: This warning is only generated if AXIS#.FAULT6004.ACTION is set to 4. |
Change Motion Task profile and clear fault with AXIS#.CLRFAULTS . |
| W7000 | Fieldbus communication lost. |
All fieldbus communication was lost. |
Check fieldbus connections (X11/X12), settings and control unit. |
| W7001 | Fieldbus sync frames lost. | The fieldbus lost synchronization. | Check fieldbus connection or the settings of your fieldbus master. |
| W7010 | Telegram selected by keywords larger than telegram of PLC. | (see PROFINET.USEMODULECFG) is set to 0 and the telegram selected by AXIS#.PROFINET.TELEGRAMID/AXIS#.PROFINET.SUPPTELEGRAMID is larger than the telegram configured in the PLC. Cyclic data will be truncated to the length of the PLC’s telegram. | Change PROFINET.USEMODULECONFIG to use the PLC’s telegram in the drive or set AXIS#.PROFINET.TELEGRAMID/ AXIS#.PROFINET.SUPPTELEGRAMID to a smaller telegram or change the PLC configuration to use a larger telegram. |
| W7011 | EtherCAT Rx received before preparing Tx data finished. |
Within one fieldbus cycle, Rx data from the master was received before the drive finished calculating and copying Tx data.
|
Refer to Synchronization for details on how to validate and adjust EtherCAT synchronization settings or deactivate this warning by setting ECAT.ENRXWARN to 0. |
| IRT configured without isochronous mode. | IRT has been enabled without setting isochronous mode when using telegrams 3 or 5 on either axis. | It is recommended to enable isochronous mode in the PROFINET controller when using telegrams 3 or 5 to guarantee synchronization. If isochronous mode cannot be enabled, the warning can be disabled and bypassed by setting PROFINET.ENISOWARNING to 0. | |
| W7014 | EtherNet/IP dynamic map size exceeds assembly size. | Adjustable sized EtherNet/IP assemblies are in use and either the dynamic command or response maps are larger than the assembly sizes. | Either reduce the number of parameters mapped in the command/response maps or increase the size of the adjustable size EtherNet/IP assemblies being used by the PLC. See Dynamic Assemblies. |
| W7015 | Fieldbus velocity command too low. | Fieldbus commanded a velocity lower than the minimum limit.
Note: This warning is only generated if AXIS#.FAULT7015.ACTION is set to 4. |
Increase fieldbus velocity command. Velocity is clamped at AXIS#.VL.LIMITN. |
| W7016 | Fieldbus velocity command too high. | Fieldbus commanded a velocity higher than the maximum limit.
Note: This warning is only generated if AXIS#.FAULT7016.ACTION is set to 4. |
Reduce fieldbus velocity command. Velocity is clamped at AXIS#.VL.LIMITP. |
| W7018 | Fieldbus cyclic position command not received in time. | One or more fieldbus position setpoints took too long to arrive. If this occurs three or more times in a row, it will trigger F7019. Note: This warning is latched until the drive stops following controller position. | Configure timing properly on the controller side. Ensure the drive and controller clocks are being synchronized. Verify EIP.PLLMODE is set to 1 (CIP Sync). |
| W9000 | Warning: Safe torque off | Safe torque off function has been triggered. W9000 is only generated if AXIS#.SAFE.STO.REPORTFAULT is 1. | Reapply supply voltage to STO if safe to do so. |
| W9007 | Safe brake parameters inconsistent. | The safe parameters, AXIS#.SAFE.SBC.BRAKE#ATTACHED, indicate a brake is attached, but non-safe brake keywords, AXIS#.MOTOR.BRAKE , BRAKE#.AXIS, do not and drive was enabled. |
From the safety parameter screen in WorkBench under safe brake control (SBC), verify the SBC Brake parameters agree with the drive related parameters that a brake is configured or not.
The keywords AXIS#.MOTOR.BRAKE, BRAKE#.AXIS, and SBC configuration all must agree with each other. For example, if no brake is present AXIS#.MOTOR.BRAKE should be 0 and safe parameters for SBC should indicate ‘Not Configured’. If brake is present, AXIS#.MOTOR.BRAKE should be 1, BRAKE#.AXIS should be assigned to proper axis, and safe parameters for SBC should be set to ‘Configured…’
AXIS#.SAFE.SBC.BRAKE1ATTACHED and AXIS#.SAFE.SBC.BRAKE2ATTACHED can be verified for the currently active safe parameters. |
| W9008 | Warning: Brake Test Time Overflow | A safe brake test has not been executed within the configured time limit. | Extend safe brake test time limit or execute a safe brake test. |
| W9009 | Warning: SMM Over Temperature | Safe motion module is over temperature. | Replace hardware. |
| W9010 | Warning: SMM State not operational | Safe motion module is not ready to enable. | Verify safe ID and safe parameters are validated and correct. Check for other faults on the safe motion monitor. |
| W9011 | SMM I/O failure detected. | SMM I/O failure detected. | Update to latest firmware. If problems persist, contact Customer Support. |
| W9012 | Safe brake test cannot start. | Pre-conditions are not met. | Prepare the axis for a safe brake test. Axis must not be faulted, enabled, and at a standstill. All attached brakes must be released. |
| W9013 | Safety rotary switch value differs from validated safe ID. | The rotary switches were changed after the drive completed start-up. | Change the rotary switch value to match the validated safe ID or reboot the drive to validate a new safe ID. |
| W9014 | Developer SMM firmware version detected. | A developer firmware image is on the SMM board. | Load official release firmware. |
| W9015 | Non-certified SMM-drive firmware version pair detected | The SMM and drive firmware images were not certified to function properly together. | Load SMM and drive firmware that have been certified together. Currently, there are only two certified version pairs:
|
| W9016 | Mismatch in drive and SMM safety parameter version | The safety parameter version used at drive startup doesn't match the SMM firmware version. | Reboot the drive. If problem persists, contact Customer Support. |
