9.2.2 Resetting the error/fault
• A fault can only be reset via bit 7 in the Controlword ( 0x6040 or 0x6840 for axis B).
• If there is another fault pending after resetting the fault, bit 3 in the status word remains set
and object 0x603F (or 0x683F for axis B) now shows the error code of this fault.
• Certain errors can only be reset by 24 V mains switching. These are, for instance, internal errors
due to internal communication faults, initialisation errors, and checksum errors of the firmware
or the persistent data (elapsed-hour meters and power-on hour meters, calibration values, etc.).
• Certain errors (e.g. earth fault or short circuit of the motor phases) can cause a delay time. In this
case, the fault can only be reset via bit 7 in the Controlword after the delay time has elapsed.
• Active delay times are displayed via bit 14 in the Lenze status word ( 0x2831 or 0x3031 for axis
B).
• The remaining delay time can be read out via the following object:
0x2840 | 0x3040 - Delay time: Reset error
0x2841 | 0x3041 - Reset error
In parallel to the execution of a quick stop in the "Fault reaction active" device status, this timer is started.
Depending on which of the following two conditions occurs first, the device status changes from "Fault reaction
active" to "Fault":
• Condition 1: Quick stop has braked the drive to standstill.
• Condition 2: This timer has elapsed.
The status change to "Fault" triggers a pulse inhibit and, if available, the holding brake is applied.
Note!
In case of setting "-2: Quick stop if possible..." in 0x605E (or 0x685E for axis B):
If due to an encoder error, quick stop is replaced by DC current braking or short-circuit braking, a standstill cannot
be detected anymore. In this case, only the condition 2 (timer has elapsed) causes an exit of the "Fault reaction
active" device status.
