Machine data
2.4 Axis-specific machine data
Description: The oscillation time defined here is active in the M4 direction.
MD irrelevant to:
• All spindle modes except oscillation mode
• Oscillation via PLC (NC/PLC interface signal DB380x DBX2002.4 (Oscilla-
tion via PLC) enabled)
Related to:
MD35440 $MA_SPIND_OSCILL_TIME_CW (oscillation time for M3 direction)
MD10070 $MN_IPO_SYSCLOCK_TIME_RATIO (interpolator cycle)
NC/PLC interface signal DB380x DBX2002.5 (Oscillation speed)
NC/PLC interface signal DB380x DBX2002.4 (Oscillation via PLC)
Description: For SW 4.2 and higher:
Byte = 0:
The path interpolation is not affected
Byte = 1:
The path interpolation is not enabled (positioning axes continue traversing)
until the spindle has reached the specified speed. The tolerance range can be
set in MD 35150: $MA_SPIND_DES_VELO_TOL. If a measuring system is active,
then the actual speed is monitored, otherwise the set speed. Path axes tra-
versing in continuous-path mode (G64) are not stopped.
Byte = 2:
In addition to 1, traversing path axes are also stopped before machining
begins, e.g. continuous-path mode (G64) and the change from rapid traverse
(G0) to a machining block (G1, G2,..). The path is stopped at the last G0
block, and does not start traversing until the spindle is within the set
speed range.
Restriction:
If the spindle is newly programmed by the PLC (FC18) or a synchronized action
"shortly" before the end of the last G0 block, then the path decelerates tak-
ing the dynamic limitations into account. Because the spindle programming is
asynchronous, a traverse can be made into the machining block if necessary.
If the spindle has reached the setpoint speed range, then machining starts
from this position.
Byte = 3:
No longer available for SW 5.3 and higher.
