3.2.2.26 G61 Stop block preprocessing
Carry out time synchronization with coarse interpolator.
G61
With the G61 function, the block preprocessing of the interpreter can be
temporarily stopped, i.e. the interpretation of the next block is stopped until
the last block has been processed in the order buffer of the coarse
interpolator.
If G61 is used within a profile, this forces the axes on the path to come to a
temporary stillstand, since no connection speed can be determined without
a connection block.

3.2.2.27 G74 Home position approach
The preparatory function G74 is used to execute the home position
approach.
G74 AXES
AXES Validity identification (any value)
There are two home position approach possibilities.
If the function G74 is programmed without other addresses in a DIN block,
the automatic home position approach is executed in the sequence which is
defined in the machine constants.
If individual axes are specified, the home position approach is only carried
out in the programmed axes.
The direction of the home position approach is defined by the corresponding
machine constant of the axis, i.e. the direction corresponds to the automatic
home position approach. An axis is programmed by the input of any
single−digit number under the corresponding axis address.
G74 X The home position approach is carried out for the configured axes in the
configured sequence.
