Acceleration measures via MD

Machine data settings
The processing speed of the entire SERUPRO operation can be accelerated using the following machine data.
MD22600 $MC_SERUPRO_SPEED_MODE and
MD22601 $MC_SERUPRO_SPEED_FACTOR
With MD22600 $MC_SERUPRO_SPEED_MODE == 1, the SERUPRO operation will run at the usual "dry run
feedrate".
Through MD22600 $MC_SERUPRO_SPEED_MODE == 0
MD22601 $MC_SERUPRO_SPEED_FACTOR is evaluated,
and a further acceleration is permitted. Dynamic monitoring functions are disabled in this mode.
SPEED factor for channel axes during ramp-up
Machine data MD22600 $MC_SERUPRO_SPEED_MODE is effective for the following channel axes in the main
run throughout the entire SERUPRO operation:
• PLC axes
• Command axes
• Positioning axes
• Reciprocating axes
The functions of MD22600 $MC_SERUPRO_SPEED_MODE and
MD22601 $MC_SERUPRO_SPEED_FACTOR apply only to SERUPRO and not to program testing. In this case
no axes/spindles are moved.
CAUTION
The NC as a discrete system generates a sequence of interpolation points.
It is possible that a synchronized action that was triggered in normal operation will no longer
be triggered in SERUPRO.
Mode of functioning with DryRun
An active SERUPRO SPEED­FACTOR has the following effect on DryRun:
• DryRun is activated simultaneously.
This causes a switch from G95/G96/G961/G97/G971 to G94 in order to execute G95/G96/G961/G97/
G971 as quickly as you wish.
• Tapping and thread cutting are performed at the usual velocity for DryRun.
DryRun and SERUPRO affect the spindle/axis with the following G codes:
