The following machine data can be changed as related units of data by switching over the
parameter set during operation:
● MD31050 DRIVE_AX_RATIO_DENOM[n] (load gearbox denominator)
● MD31060DRIVE_AX_RATIO_NUMERA[n] (load gearbox numerator)
● MD32200 POSCTRL_GAIN[n] (servo gain factor).
● MD32810 EQUIV_SPEEDCTRL_TIME[n] (equivalent time constant speed control loop for
● MD36200 AX_VELO_LIMIT[n] (threshold value for velocity monitoring)
Index[n] of the machine data is coded as follows: [closed-loop control parameter set no.]: 0-5
Spindle parameter sets:
In the case of spindles, each gear stage is assigned its own parameter set. The relevant
parameter set is activated in accordance with the "Actual gear stage" IS (V380x 2000.0 to
.2). The machine data that is changed over with the spindle gear stage is listed in the section
titled "Spindles".

Axis parameter sets
● Parameter set 1 (index=0) is always activated for axes not involved in tapping or thread
● For axes involved in tapping or thread cutting, the same parameter set number as for the
Note
If, for example, a load gearbox is active for an axis, this ratio (numerator, denominator) must
be entered in all other parameter sets used for threads in addition to the parameter set with
index=0.
The current parameter set is displayed in the "System" → "Service Display" operating area on
the "Service Axes" screen.
