General feed disable

GENERAL FEED DISABLE
1 signal: Effects feed hold of all interpolator controlled axes provided that no G 33 (thread
cutting) signal is present.
0 signal: Effects feed enable of all axes.
Notes:
• The signal is effective only in the automatic modes.
• When GENERAL FEED DISABLE is selected, all axes in motion are brought to a standstill
along the contour. Position control remains operative, i.e. the following error is reduced to
zero.
• GENERAL FEED DISABLE is activated if at least one bit in DW 6 is set.
• If an axis must not be traversed in any mode due to interlock conditions, this must be
prevented for the specific axis with FEED DISABLE.
• A message can be allocated to any FEED DISABLE bit.
