2.6 Block search Type 5 SERUPRO
2.6.2
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 additional 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.
• Tapping and thread cutting are performed at the usual velocity for DryRun.
DryRun and SERUPRO affect the spindle/axis with the following G codes:
72
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.
Basic logic functions: Mode group, channel, program operation, reset response (K1)
