Machine data
MD31050
DRIVE_AX_RATIO_DENOM[n]
(load gearbox denominator)
"-" Does not apply to this combination.
The coding of the machine data MD... DRIVE_AX_... index [n] is: [closed-loop control parameter set no.]: 0-5
Note
*) These MD are not required for encoder matching (path evaluation). However, they must
be entered correctly for the setpoint calculation! Otherwise the required servo gain factor will
not be set.
Variants of actual-value acquisition
The associated machine data for different variants of actual-value acquisition is described
below.
