Number / Alarm Cause
A148 The current deceleration value is 0, e.g.
because of a RAM storage error or an error in
Deceleration = 0 the technology firmware.
Effect:
The position control system is deactivated and
the drive is decelerated via the "deceleration
time during errors" (machine data 43).
A149 Internal error in the technology software.
Distance to go negative Effect:
The position control system is deactivated and
the drive is decelerated via the "deceleration
time during errors" (machine data 43).
A150 The selected NC program contains a slave
axis which is already being used by another
Slave axis already master axis (M7 only, not significant for the
allocated to other F01 technology option).
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
Slave axis operating for the F01 technology option).
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,
Slave axis operating not significant for the F01 technology option).
mode changed
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A153 A warning is active in the slave axis required
by the master axis (M7 only, not significant for
Error in slave axis the F01 technology option).
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A154 The "follow-up mode" [FUM] control signal is
active in the slave axis required by the master
Follow-up mode in axis. A slave axis which is switched to follow-
slave axis active 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
deceleration ramp.

Counter-measure
This fault should not normally occur. It is used
as an emergency stop feature for the
technology software.
Replace the hardware (M7; MCT).
This fault should not normally occur. It is used
as an emergency stop feature for the
technology software.
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.
