Error Messages
The LED display on the servo drive's front panel displays errors that occur as an error number.
All error messages cause the ready for operation contact to be opened and the servo drive's output stage to be switched off. The motor generates no torque, and the motor's holding brake is applied.
Error | Designation | Explanation |
|---|---|---|
F01* | Heatsink temperature | Heatsink temperature too high. Limit value set by the manufacturer to 80° C. |
F02* | Overvoltage | Overvoltage in DC link. Limit value depends on the mains voltage. |
F03* | Following error | Message from position controller |
F04 | Feedback | Broken cable, short-circuit, earth short |
F05* | Undervoltage | Undervoltage in DC link. Limit value set by the manufacturer to 100V. |
F06 | Motor temperature | Temperature sensor faulty or motor temperature too high. Limit value set by the manufacturer to 145°C. |
F07 | Auxiliary voltage | Internal auxiliary voltage not correct |
F08* | Overspeed | Motor out of control, rotation speed unacceptably high |
F09 | EEPROM | The "F09" fault occurs if the checksum for the data and parameters in the EEPROM is not correct (can be caused, for instance, if power is removed from the drive while the parameters are being saved). This error can result either from a faulty EEPROM or from a faulty data checksum. In the second case, the fault can be rectified by saving the data (SAVE) again. |
F10 | Flash-EPROM | Checksum error |
F11 | Brake | Broken cable, short-circuit, earth short |
F12 | Motor phase | A motor phase is missing (broken connection or similar) |
F13* | Internal temperature | Internal temperature too high |
F14 | Output stage | Fault in the power output stage |
F15 | I²t max. | I²t maximum value exceeded |
F16* | Mains BTB | Two or three phases are missing from the supply |
F17 | A/D converter | Fault in the analog/digital conversion, usually caused by exceptional electromagnetic interference |
F18 | Ballast | Ballast circuit faulty, or setting not correct |
F19* | Mains phase | Absence of a phase from the supply (can be switched off for operation with two phases) |
F20 | Slot error | Slot error |
F21 | Handling error | Software error in the extension card |
F22 | Earth short | Only for 40/70 amp devices: Earth short |
F23 | CAN Bus off | Serious CAN Bus communication error |
F24 | Warning | Warning indication is interpreted as an error |
F25 | Commutation error | Commutation error |
F26 | Limit switch | Reference transit error (hardware limit switch reached) |
F27 | AS option | Fault in the operation of the AS option (control of the AS option and the ENABLE signal are present at the same time) |
F28 | EtherCAT synchronization error | EtherCAT synchronization error (e.g. jitter, double MDT error) |
F29 | EtherCAT configuration error | EtherCAT configuration error (e.g. Sync Manager parameterization) |
F30 | Emergency stop timeout | The "F30" error ("Emergency stop timeout") occurs when, in the case of a Stop or of an Emergency stop, the axis cannot physically be brought to a halt within a parameterized time window (default: 5000 ms, see <EMRGTO>) (halt limit <VEL0>: 5 RPM). This error can be triggered if very soft ramps are parameterized in the drive (see <DEC>, <DECSTOP>, <DECDIS>). |
F31 | Macro error | Error in the macro programming |
F32 | System error | The "F32" error ("System error") indicates an internal error. This error is generated when the servo drive is switched on if it has not been possible to successfully complete the system check during the initialization phase (see the output from the RS232 serial interface for the exact cause of the error). The error can also occur if the servo drive is too heavily loaded when cycle times a very short (see Runtime optimization). |
*) These error messages can be cleared with the CLRFAULT ASCII command without carrying out a reset.
If only one of these faults is present, and the Reset button is pressed or the Reset I/O function is used,
then again only the CLRFAULT command will be executed.
