S700, S300, S600, and S400 F24 Fault Code

The F24 fault is created by the WMASK feature which allows a defined Warning (nX warning) to generate a fault message (defined by WMASK)

WMASK is a bit-variable, with bit assignments that correspond to the STATCODE * status variable. The bit that is set within the WMASK variable means that the corresponding warning bit in the STATCODE * variable should generate an F24 fault message, as well as a warning. Unlike warnings, a fault message results in the disabling of the output stage, and the opening of the RTO contact.

A reconfiguration can be especially relevant for changing a following error n03 (this is normally indicated as a warning) to a fault. The value has to be entered in decimal.


The STATCODE * command returns the internal warnings in the form of a bit-variable. The assignments for the individual bits can be seen in the following table.

Bit Display Meaning
0 / 0x00000001 n01 =1 I2T Threshold override
1 / 0x00000002 n02 =1 Regen message
2 / 0x00000004 n03 =1 Contouring error
3 / 0x00000008 n04 =1 watchdog limit reached
4 / 0x00000010 n05 =1 Line phase missing
5 / 0x00000020 n06 =1 Software limit switch 1 active
6 / 0x00000040 n07 =1 Software limit switch 2 active
7 / 0x00000080 n08 =1 Wrong motion task started
MJOG activates the warning, if ACCR or DECR value is out of range

14 / 0x00004000 n15 =1 Wrong VCT entry started
15 / 0x00008000 n16 Is active, if one or more of the warnings n17...n31 are active.
16 / 0x00010000 n17 =1
The mode synchronization SYNCSRC is selected but the drive isn't in synchronies cycle
17 / 0x00020000 n18 Using Multiturn encoder feedback, a overrun over the maximum number of resolutions (+/-2048) was detected (starting with firmware 4.91)
18 n19 The motion task ramps are limited (range overflow on motion task data)
19 n20 Wrong GMT data
