Effects when the limit value is exceeded for SG

Configurable stop response

When the selected speed limit value is violated, a stop response configured in the

following machine data/parameters is generated:

for 840D sl:

MD36961 $MA_SAFE_VELO_STOP_MODE

MD36963 $MA_SAFE_VELO_STOP_REACTION[n]

for SINAMICS S120:

p9561 SI Motion SLS (SG) stop response (Control Unit)

p9563[0...3] SI Motion SLS (SG)--specific stop response (Control Unit)

S An alarm is displayed (for 840D sl: 27011, for SINAMICS S120: F01714). After

the cause of the fault has been removed, the alarm can be acknowledged with

RESET. The monitoring function is then again active.

S Depending on the selected monitoring clock cycle, the dynamic drives may

cause a brief increase in speed on the monitored axis/spindle before the stop

response sequence starts.

S For traversing modes which use a transformation with singularity points

(e.g. 5--axis transformation and TRANSMIT), relatively high axis--specific

speeds occur at these points. These speeds can initiate stop responses even

though the Cartesian motion of the tool center point (TCP) is below the

selected speed limit value.

The monitoring functions provided by SI are basically axis--specific. This means

that it is not possible to directly monitor the TCP.
