Rapid traverse and
feed rate limitation If more than one axis is moved simultaneously, the rapid traverse on the path
vpath is formed from the appropriate axis components.

In MP_maxFeed, define the maximum rapid traverse for this axis.
Feed rate and rapid traverse are significantly lower for Manual Operation:

Define the feed rate for manual mode in MP_manualFeed.

Define the feed rate for rapid traverse in MP_rapidFeed.
If the value in PP_ChnContourFeedMax is greater than the value in
MP_maxFeed, the parameter value applies. After the control is switched on,
or after an interruption of the PLC run, PP_ChnContourFeedMax is assigned
the value 300 000 so that MP_maxFeed becomes effective.
The maximum possible feed rate depends on the encoder being used.
vmax [mm/min] = P [mm] · fi [kHz] · 60
vmax = Maximum traverse speed
P = Signal period of the encoder
fi = Input frequency of the encoder input (see “Chapter 3.5, Mounting and
Electrical Installation”)
Analog axes: The rapid traverse rate at an analog voltage of 9 V is defined in
MP_maxFeedAt9V.
Feed rate values in
PLC operands The feed rate values are indicated in PLC operands (see the following tables).
The PLC can influence the following values:
 PP_ChnContourFeedMax: Maximum feed rate
 PP_AxManualFeedMax: Maximum manual axis feed rate
v
axis 2
v
axis 1
v
path
Note
The absolute maximum velocity of this axis is defined in MP_maxFeed. This
value is not exceeded.
