Activate fixed feed rate 1 - 4 for machine axes
Edge evaluation: no
Signal(s) updated: cyclic
Description
These signals are used to select/de-select the function "fixed feed" and define which fixed feed
should be effective for machine axes.

Feed stop/spindle stop (axisspecific)
Edge evaluation: no
Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The signal is active in all modes.
Feed stop:
The signal triggers a "feed stop" for the axis. This signal brings all traversing axes to a standstill
with controlled braking (ramp stop). No alarm is output.
The signal triggers a "feed stop" for all path axes interpolating relative to each other when the "feed
stop" is activated for any one of these path axes. In this case, all the axes are brought to a stop with
adherence to the path contour. When the "feed stop" signal is canceled, execution of the interrupted
parts program is resumed.
The position control is retained, i.e. the following error is eliminated.
If a travel request is issued for an axis with an active "feed stop", this is kept. This queued travel
request is executed immediately after the "feed stop" is canceled.
If the axis is interpolating in relation to others, this also applies to these axes.
Spindle stop:
The spindle is brought to a standstill along the acceleration characteristic.
In the positioning mode, when the "Spindle stop" signal is set positioning is interrupted. The above
response applies with respect to individual axes.
Signal state 0 or
edge change
1 → 0
Feed stop:
The feed rate is enabled for the axis.
If a travel request ("travel command") is active when the "feed stop" is canceled, this is executed
immediately.
Spindle stop:
The speed is enabled for the spindle.
The spindle is accelerated to the previous speed setpoint with the acceleration characteristic or, in
positioning mode, positioning is resumed.
