Description of application faults

At a Glance

These faults are signaled by the AX_ERR bit (%Ir.m.c.5). The parameters can be accessed via the Configuration editor adjustment screen.

Soft stops

The following table shows the cause, the signal and the remedy to be applied in the case of a Soft stop fault: This fault is blocking and cannot be deactivated.

Cause	The moving part is no longer situated between the 2 thresholds: software Lo limit and software Hi Limit (this monitoring is activated as soon as the axis is referenced)
Parameters	Software Hi Limit: SL_MAX (%MDr.m.c.14) Software Lo Limit: SL_MIN (%MDr.m.c.16)
Consequence	The moving part is forced to stop
Signal	SLMAX bit (%MWr.m.c.3.3): Software Hi Limit passed SLMIN bit (%MWr.m.c.3.4): Software Lo Limit exceeded
Remedy	Acknowledge the fault and, in manual mode, remove the moving part exceeding the soft stops to within the valid measurement zone. To do that, you must check: that no movement is in progress, that manual mode is selected, that the STOP command is set to 0, that the axis on which the command is carried out is referenced, that there is no other fault with stop on the axis. The moving part can either be brought back manually or by means of the commands JOG+ and JOG-.
