2.1.2 Response to RESET and function abort
Response to RESET
During selection (fixed stop not yet reached) the function FXS can be aborted with RESET.
The termination is carried out such that an "almost achieved" fixed stop (setpoint already
beyond the fixed stop, but still within the threshold for the fixed stop detection) will not result
in damage.
This is achieved by synchronizing the position setpoint to the new actual position. As soon
as the fixed stop is reached, the function remains operative even after RESET.
Function abort
A function abort can be triggered by the following events:
• EMERGENCY STOP:
– With an 840D control, the NC and drive are disconnected from the supply after
EMERGENCY STOP, i.e. the PLC must react.
– With an 840Di control, the NC and drive are disconnected from the supply after
EMERGENCY STOP, i.e. the PLC must react.
Caution
Make sure that after canceling the function
"travel to fixed stop" by "EMERGENCY STOP," no dangerous machine situation
(MD37002 $MA_FIXED_STOP_CONTROL e.g. canceling pulse disable) can arise.
• The fixed stop monitoring function responds in the case of:
– Exit from fixed stop position by axis
– Tool breakage
– Pulse disable
