Error Cause of error
number
When you were downloading the
current position value from the EnDat
encoder (only following switch-on of
machine), an error was detected in
the encoder. If the speed encoder is
used for reading the position value,
the evaluation is the same.
The cause of the error is transferred
as a status bit and displayed on the
TNC with 5 status bits:
xxxxx = xx001 Light source
xx010 Signal amplitude
xx100 Position value
Encoder cable defective.
Encoder defective.
Encoder input on TNC defective.
509 FK programming: An FK block in
which CLSD (contour end) is
programmed contains incremental
axis coordinates.
58 The calculated path of the tool
exceeds the traversing range
(software limit switch) of the
machine.
The calculated path of the tool
exceeds the traversing range
(software limit switch) of the
machine.
1798 The digitizing range exceeds the
traversing range (limit switch).
2232 In the active part program there are
ERROR blocks that cannot be run
by the iTNC (e.g. TOOL DEF block
—ISO: G99 block — with active tool
file).
200 The interface is not connected.
The external unit is not switched on
or not ready.
The transmission cable is defective
or incorrect.
182 The "control-is-ready" input is not
active.
Corrective action
Exchange the encoder cable.
Exchange the encoder.
Use another encoder input on the
TNC.
defective
too low
incorrect
Use CLSD only with absolute axis
coordinates.
Check the programmed
coordinates, and if necessary edit
the program.
Check the datum, and if necessary
reset the datum.
Check the programmed
coordinates, and if necessary edit
the program.
Check the datum, and if necessary
reset the datum.
Check the values in the Range
cycle.
If necessary, reset the datum.
If necessary, delete the entire
ERROR block.
In the Programming and Editing
mode, select the ERROR block
and, with the rightward arrow key,
go into the block. Edit the block and
exit it with END. When the error is
eliminated, the TNC automatically
cancels the word ERROR.
Check the data transfer line.
Check the emergency-stop circuit.
