Target position
You can approach a target position in various modes. A new block is not written
until you press "Exec" while the drive is at zero speed.
Table 5-12. Target Specification in Mode 10
Target position is specified
by approaching it in
mode 1
mode 2
by entering the coordinate in
mode 6
mode 7
Speed
You can specify a new target position in modes 1, 2/3, 6 and 7. This allows
positioning to take place at the speeds specified in the machine data. You can
vary these speeds via an Override factor, thus enabling extremely exact
positioning.
Incremental speed 100% is always entered for each traversing program block
generated in teach-in mode.

The modes can be started by selecting one of the following
functions:
