The following selection sets the balancing times (in MD32800
$MA_EQUIV_CURRCTRL_TIME or MD32810 $MA_EQUIV_SPEEDCTRL_TIME) of all
involved axes to the largest time constant:
● The following questions must be answered:
– Which axis parameter set may be reparameterized (for the path interpolation)?
– May the first axis parameter set be overwritten?
– Does the spindle need to be part of the path interpolation?
– If the thread cutting should also run with this axis configuration, parameter set 2 for the
● Save the original path data!
Programming
Note
In the following program example, those cycle calls required for the reoptimization are
highlighted bold.
Any cycle calls not highlighted are optional.
DEF INT myaxiswithnewload=4
; Switch to a safe data set.
; Traverse axis to the safe position / home position.
; Strategy settings were made from the user interface: target value for the equivalent time!
; Is a destination data set (DDS) available that may be overwritten?
CYCLE751(1)
; Optimize axis 4, with path interpolation.
; Select strategy:
CYCLE752(myaxiswithnewload,3,true)
CYCLE752(1,3,true)

axes and the gear stages in the spindle (parameter set 2 ... 6) may need to be optimized.

; Open the optimization session.
; Add axis 4, accept optimization strat-
egy from the standard optimization file
(XML file), consider the axis for an op-
timization of the path interpolation.
; Add axis 1 because of the path inter-
polation.
