17.4.2 Feedrate disable and feedrate/spindle stop
General
The feedrate disable or feedrate/spindle stop brings the axes to a standstill with adherence to the braking
characteristics and the path contour (exception: G33 block).

"Feedrate disable" DB21, ... DBX6.0
Interface signal "Feedrate disable" (DB21, ... DBX6.0) shuts down all axes (geometry and auxiliary axes) of a
channel in all modes.
"Feed stop" DB21, ...DBX12.3 geometry axes
Interface signals "Feed stop" (DB21, ... DBX12..3 and the following signals) for geometry axes 1, 2, and 3 stop
the geometry axes of a channel in JOG mode.
"Feed stop" DB31, ...DBX4.3 axisspecific
The axis-specific "Feed stop" interface signal (DB31, ... DBX4.3) is used to stop the relevant machine axis.
In automatic mode:
• If the "Feed stop" is performed for a path axis, all the axes traversed in the current block and all axes
participating in the axis group are stopped.
• If the "Feed stop" is performed for a positioning axis, only this axis is stopped.
Only the current axis is stopped in JOG mode.
Axis/spindle disable" DB31, ... DBX1.3
Activating "Axis/spindle disable" (DB31, ...DBX1.3) disables the axial PLC interlocks "No controller enable" and
"Feed stop".
The axial and channelspecific override, however, is active.
Activation of channel-specific feedrate disable
If G33, G34, G35 active: Not effective
If G63 active: Effective
If G331, G332 active: Effective
Activation of axis-specific function "Feed stop"
Active in G33, G34, G35 Effective
(causes contour deviations)
For active G63 Effective
In active G331, G332 Effective
