These PLC interface signals are used to define whether this machine axis
is assigned to handwheel 1 or 2 or is not assigned to any handwheel.
Only one handwheel can be assigned to an axis at any one time.
If several interface signals "Activate handwheel" are set, then the following
priority applies: Handwheel 1 before handwheel 2.
If the assignment is active, then the machine axis can be traversed using the
handwheel in the JOG mode.
This machine axis is neither assigned to handwheel 1 nor 2.
The PLC user program can use this interface signal to interlock the influence
on the axis by turning a handwheel.

Function Manual Basic Functions H1
Feedrate stop / spindle stop (axis-specific)
Signal(s) to axis / spindle (PLC → NCK)
Signal(s) updated: Cyclic
The signal is active in all modes.
Feedrate stop:
● The signal triggers a feedrate stop for the axis. For a traversing axis, this
signal brings it to a standstill with a controlled braking (ramp stop). No
alarm is output.
● The signal triggers a "feedrate stop" for all path axes interpolating relative
to each other when the "feedrate stop" is activated for any one of these
path axes. In this case, all the axes are brought to a stop maintaining the
path contour. When the feedrate stop signal is withdrawn, execution of
the interrupted parts program is resumed.
● The position control is kept, i.e. the following error is eliminated.
● If a travel request is issued for an axis with an active "feedrate stop", then
this is kept. This pending travel request is executed directly when
"Feedrate stop" is withdrawn.
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.
Feedrate stop:
● The feedrate is enabled for the axis.
● If a travel request ("travel command") is active when the "feedrate stop"
is withdrawn, this is executed immediately.
Spindle stop:
● The speed is enabled for the spindle.
● When "spindle stop" is withdrawn, the spindle is accelerated to the
previous speed setpoint with the acceleration characteristic or, in the
positioning mode, positioning is resumed.
