Is this possible to generate an alarm in case of belt failure in the servo motor and can able to generate an alarm in master drive. pleasekindlyreply me for my query.

The other way I can think of (but this might be quite fiddly) is to use some logic and the Comparison reached bit in Status word 1, bit 10.

See Attachment, for example, use B104 (Drive running) AND B121 (Comparison Value Not OK), if the drive is running, but the torque drops below say 10%, then the user defined trip is activated.

I think you may have headaches this way though, as the torque may naturally drop below 10% when the machine is decelerating. This may mean you have to stop the drive with an OFF2, but if you are using a positioning application, then this may not be suitable.

I hope you have some things to experiment with now, I don't have any kit to try this on. Let us know if you find anything or maybe an easier way to implement this function.
Cheers,
Graeme
