2050 Rotary axis path is too small with G98
Scan
When executing a part program
S
Effect
Machining stops
S
Interlocking of NC start
Explanation
The traversed distance to go of the rotary axis in G98 is so small (or 0) that it is not possible to calculate a path
feedrate for the linear axes to be traversed.
Remedy
Check the programmed values in the block. If the rotary axis has to traverse a distance to go, path feed (G94)
should be used in this block.
Note
Alarm is displayed with reference to channel
2056 Travel through transformation center
Scan
When executing a part program
S
Effect
Interlocking of NC START
S
Machining is interrupted
Explanation
With TRANSMIT transformation selected, a part program block which brings about a movement directly through
the transformation centre has been programmed.
S
Remedy
Check program
S
Check whether the function "Travel through transformation center" can be used.

2057 Thread/revolutional feedrate missing
Scan
When executing a part program
S
Effect
Machining is not started or is terminated
S
Interlocking of NC START
S
Erläuterung
A thread has been programmed with G33, G34, G35 although this function has not been implemented in the
control.
S
Revolutional feedrate G95 has been programmed
S

S
A program not included in the function set of the control has been programmed
S
Remedy
Check program
S
Check NC machine data
S
Have function options upgraded.
Alarm is displayed with reference to block and channel.

result in additional axes from the programming, e.g. when setting the coordinate rotation
S
Remedy
Check program
S
Have function option retrofitted if possible
Note
Alarm is displayed with reference to block and channel
