Machine data
2.4 Axis-specific machine data
Description: The following error must have reached the limit value for exact stop fine by
the expiry of the time entered in this MD for traveling into the position
(position setpoint has reached the destination).
The current following error is therefore continuously monitored for the time
limit MD36010 $MA_STOP_LIMIT_FINE. If this time is exceeded, alarm 25080
"Positioning monitoring" is output, and the axis stopped. The time entered in
this MD should be long enough to ensure that the monitoring function is not
triggered under normal operating conditions, taking into account any settling
times.

MD 36010: $MA_STOP_LIMIT_FINE (exact stop fine)
Description: This MD serves as a tolerance band for the following monitoring functions:
• After termination of a traversing block (position partial setpoint=0 at
the end of the movement), whether the following error has reached the
limit value for MD36030 $MA_STANDSTILL_POS_TOL (standstill tolerance) is
monitored after the programmable MD36040 $MA_STANDSTILL_DELAY_TIME (delay
time, standstill monitoring).
• After termination of a positioning action (exact stop fine reached),
positioning monitoring is replaced by standstill monitoring. The axis is
monitored for moving from its position by more than defined in MD36030
$MA_STANDSTILL_POS_TOL (standstill tolerance).
If the setpoint position is over- or undershot by the standstill tolerance,
alarm 25040 "Standstill monitoring" is output and the axis stopped.
Special cases:
The standstill tolerance must be greater than the "exact stop limit coarse".
