Masking of Faults

At a Glance

With a TSX CAY •2 or TSX CAY 33 module it is possible to individually mask 4 of the 8 external faults (hardware) during channel configuration (MSK_HDERR parameter).

Mask Faults Screen

The Mask faults screen is used to define the faults that you would like to mask:

The 4 faults that you can mask are as follows:

Fault	Associated parameter
Speed controller fault	DRV_FLT
Encoder supply fault	ENC_SUP
Emergency stop fault	EMG_STP
24 V Power supply fault	AUX_SUP

Associated Variables

During a power outage, the masked faults are not signaled and the associated variables are not refreshed:

channel error bit CH_ERROR (%I.r.m.c.ERR),
status wordCH_FLT(%MWr.m.c.2).

The AX_FLT, AX_OK and HD_ERR information bits are updated without taking account of masking. All axis movement is interrupted by a stop and disabling of the variable speed controller.
