V1: Feedrates
17.4 Feedrate control
Basic Functions

For gray-coding, the override factors corresponding to the switch position should be entered in the machine data:
MD12030 $MN_OVR_FACTOR_FEEDRATE (evaluation of the path feedrate override switch)
MD12050 $MN_OVR_FACTOR_RAPID_TRA (evaluation of the rapid traverse override switch)
An active feedrate override has an effect on all path axes that are assigned to the current channel. An active
rapid traverse override has an effect on all the axes that are traversed with rapid traverse and that are assigned
to the current channel.
No rapid traverse override switch available
If there is no dedicated rapid traverse override switch, you can choose between rapid traverse override and
feedrate override. The override to be active can be selected via the PLC or operator panel front. When rapid
traverse override is active, the feedrate override values are limited to 100%.
• To activate the rapid traverse override via the operator panel front, the basic PLC program transfers the
selection of the feedrate override for rapid traverse to the activation signal for the rapid traverse override:
DB21, ... DBX6.6 = DB21, ... DBX25.3
and the feedrate override value in the rapid traverse override value:
DB21, ... DBB5 = DB21, ... DBB4
• When selecting the rapid traverse override via the PLC, the PLC user program should set the activation signal
for the rapid traverse override:
DB21, ... DBX6.6 = 1
and the feedrate override value transferred into the rapid traverse override value:
DB21, ... DBB5 = DB21, ... DBB4
