A150
The selected NC program contains a slave
axis which is already being used by another

master axis
Example:
NC program 1, started in axis X, contains NC
blocks for axes X and Y. NC program 2 is
started in axis Z and contains NC blocks for
axes Z and Y. This program is denied with
warning 150, because axis Y is already being
used by program 1.
Effect:
NC program execution is inhibited or aborted.
A151
The slave axis required by the master axis is
not in "slave" mode (M7 only, not significant

mode not allowed
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A152
The "slave" mode was deselected in the slave
axis during the traversing movement (M7 only,

Effect:

A154
The "follow-up mode" [FUM] control signal is
active in the slave axis required by the master

up mode cannot be operated by the master
axis (M7 only, not significant for the F01
technology option).
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the

A155
The "reset" [RST] control signal is active in the
slave axis required by the master axis. A slave

Counter-measure
The same slave axis cannot be used
simultaneously by several NC programs.
The slave axis must be switched to "slave"
mode.
The slave axis must remain switched to
"slave" mode.
The NC program will only run if all of the axes
it needs are error-free. To clear this warning,
you must first clear all the warnings in the
slave axis.
Deactivate follow-up mode in the slave axis.
Cancel the "reset" [RST] control signal in the
slave axis.
