Default: 1
Min. input limit: 1
Max. input limit: 2147000000
Change effective after Power On
Protection level: 2/7
Unit: Data type: DWORD
Valid as from SW version:
Meaning:
In this MD, the denominator of the resolver gearbox must be entered.
The machine data index is coded as follows: [encoder no.]: 0
31080
DRIVE_ENC_RATIO_NUMERA[n]

Resolver gearbox numerator
Default: 1
Min. input limit: 1
Max. input limit: 2147000000
Change effective after Power On
Protection level: 2/7
Unit: Data type: DWORD
Valid as from SW version:

STEP_RESOL
MD number
Steps per stepper motor revolution
Default: 1000
Min. input limit: 0
Max. input limit: plus
Change effective after Power On
Protection level: 2/7
Unit: Data type: DWORD
Valid as from SW version:
Meaning:

32000
MAX_AX_VELO
MD number
Maximum axis velocity
Default: 10000
Min. input limit: 0
Max. input limit: ***
Change effective after Power On
Protection level: 2/7
Unit: mm/min,
Umdr./min
Data type: DOUBLE
Valid as from SW version:
Meaning:
In this MD, the limit velocity up to which the axis can accelerate must be
entered (rapid traverse limiting). If rapid traverse is programmed, this velocity
is used for traversing.
The maximum admissible axis velocity is dependent on the dynamic
properties of machine and drive, as well as on the limit frequency of the actual
value sensing.
