General machine data
13070 DRIVE_FUNCTION_MASK
MD number Bit-coded screen for selecting the functional scope expected by the NC with PROFIBUS
drives
Default setting: 0 Min. input limit: 0 Max. input limit: FFFF FFFF
Changes effective after POWER ON Protection level: 2/7 unit: -
Data type: DWORD Valid as of software version: 2.1

Bit 2: Deactivation of the 611U-specific parameter access encoder drivers
Bit 3: Deactivation of the 611U-specific parameter access output drivers.
Bit 4: Activation of external drive: DSC bits (STW1.12/STA1.12)
Bit 5: Deactivation of 611U-specific drive parking (STW2.7/STA2.7)
Bit 6: Deactivation of the 611U-specific travel to fixed stop (STW2.8/STA2.8)
Bit 7: Deactivation of the 611U-specific internal motor switchover (STA2.9 to 11)
Bit 8: Deactivation of the 611U-specific ramp block (STW1.13)
Bit 9: Deactivation of the 611U-specific function generator functions (STW1.8/STA1.13)
Bit 14: Selection of non-cyclic DP communication: 0=DPT; 1=DPV1
Bit 15: Deactivation of consistency check of PROFIBUS message frame configuration
STW: Control word (PDA word in PROFIDrive message frame to DP slave)
STW: Control word (PDA word in PROFIDrive message frame from DP slave)
PDA: Process data
Axis-specific machine data
37620 PROFIBUS_TORQUE_RED_RESOL
MD number Torque reduction resolution on PROFIBUS (LSB weighting)
Default setting: 1 Min. input limit: 0.005 Max. input limit: 10
Change valid after NEWCONF Protection level: 2/7 unit: %
Data type: DOUBLE Valid as of software version: 2.2
Meaning: The default value 1% refers to the original weighting: The torque limit value is transferred to
the PROFIBUS in increments of 1%; the value 100 in the corresponding PROFIBUS data
cell signifies full torque reduction (i.e. without power).
By changing the MD to e.g. 0.005%, the raster conversion of the value in 0.005% can be
specified, i.e. the torque limit value is rasterized by the factor 200.
For restriction to the rated torque, the value 0 is transferred in this case, a full torque
reduction (i.e. without power) denotes the transferred value 10000.
To avoid wrong adaptation, the adjusted value of the machine data must be configured
according to the drive, or the permanently defined interpretation of the torque reduction
value must be selected.
