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.
