Faults and Alarms
Number / Alarm
Cause
A202
An axis which does not exist was detected in
the decoded NC block. A logical name (X, Y,
Axis unknown
Z, A, B, C) must be assigned to each axis with
machine data 2 (axis assignment). Only these
logical axis names can be used in the NC
block. These errors cannot normally occur,
since the logical axis names are verified when
the NC blocks are entered.
Exception: Machine data 2 (axis assignment)
is changed afterwards.
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values – decoder error location"
task.
Effect:
NC program execution is inhibited or aborted,
the axis is brought to a standstill via the
deceleration ramp.
A203
The NC block which was read in contains an
illegal 1st G function.
1st G-function not
allowed
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
A204
The NC block which was read in contains an
illegal 2nd G function.
2nd G-function not
allowed
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
A205
The NC block which was read in contains an
illegal 3rd G function.
3rd G-function not
allowed
The NC program number and NC block
number in which the NC block decoder
detected the error can be read out with the
"output actual values - decoder error location"
task.
Effect:
The axis movement is inhibited or stopped via
the deceleration ramp.
12-28
Counter-measure
Correct the NC block.
-MDI mode:Only G90 (absolute dimensions) or
G91 (incremental dimensions) can be entered
as the 1st G function. Only G91 is allowed for
the roll feed version.
-Automatic/single-block mode:Define a legal
1st G function according to the table (see the
Programming Guide).
-MDI mode:Only G30 to G39 (acceleration
override) can be entered as the 2nd G
function.
-Automatic/single-block mode:Define a legal
2nd G function according to the table (see the
Programming Guide).
-MDI mode:No 3rd G function is allowed.
-Automatic/single-block mode:Define a legal
3rd G function according to the table (see the
Programming Guide).
