Number / Alarm Cause
A145 The "digital input" with the "disable actual
value" function was actuated while the roll
Actual-value disable feed was running.
not allowed - axis
standstill Effect:
The axis movement is stopped via the
deceleration ramp, the "disable actual value"
function is not executed.
A146 A positioning movement was aborted. When
attempting to resume the movement at the
Direction of movement point of interruption, the roll feed would have
not allowed had to travel in the opposite direction to reach
the programmed target position. This is
inhibited by the setting of machine data 37
"response after abort".
There are various possible reasons for the
axis crossing the target position when a
positioning movement is aborted:
- Motor coastdown
- The axis was moved intentionally, e.g. in
setup mode.
Effect:
The axis movement is inhibited.
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.

Counter-measure
The "digital input" for "disable actual value"
can only be actuated when the axis is
stationary.
Move the axis in front of the target position in
setup mode before continuing.
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.
