2.4 Axis-specific machine data
Description: Threshold for exact stop coarse
An NC block is considered as terminated if the actual position of the path
axes is away from the setpoint position by the value entered for the exact
stop limit. If the actual position of a path axis is not within this limit,
the NC block is considered as not terminated, and further part program execu-
tion is not possible. The magnitude of the value entered influences the tran-
sition to the next block. The larger the value, the earlier the block change
is initiated.
If the specified exact stop limit is not reached, then
• the block is considered as not terminated,
• further traversing of the axis is not possible,
• alarm 25080 Positioning monitoring is output after expiry of the time
specified in MD36020 $MA_POSITIONING_TIME (monitoring time for exact stop
fine),
• the direction of movement +/- is indicated for the axis in the position-
ing display. The exact stop window is also evaluated for spindles in
position control mode (SPCON instruction).
Special cases:
MD36000 $MA_STOP_LIMIT_COARSE must not be set smaller than MD36010
$MA_STOP_LIMIT_FINE (exact stop fine). To achieve the identical block change
behavior as with the "exact stop fine" criterion, the exact stop coarse win-
dow may be identical to the exact stop fine window. MD36000
$MA_STOP_LIMIT_COARSE must not be set equal to or greater than MD36030
$MA_STANDSTILL_POS_TOL (standstill tolerance).
