18.3.8 Data description (MD)
13070 DRIVE_FUNCTION_MASK
MD number Bit–coded screen for selecting the functional scope expected by the NCK with PROFIBUS
drives
Default setting: 0 Min. input limit: 0 Maximum input limit: FFFF FFFF
Changes effective after POWER ON Protection level: 2/7 Units: –
Data type: DWORD Applies from SW version: 2.1
Significance: Meaning of set bits:
Bit 0: Deactivation of the 611U–specific drive alarm mapping
Bit 1: Deactivation of the 611U–specific drive type detection
Bit 2: Deactivation of the 611U–specific parameter accesses encoder drivers
Bit 3: Deactivation of the 611U–specific parameter accesses output drivers
Bit 4: Activation third–party drive: DSC bits (STW1.12/STA1.12)
Bit 5: Deactivation of the 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 (STA2.9–11)
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 for PROFIBUS message frame configuration
CTW: Control word (PDA word in the PROFIDrive message frame to DP slave)
STW: Status word (PDA word in the PROFIDrive message frame from DP slave)
PDA: Process data
37620 PROFIBUS_TORQUE_RED_RESOL
MD number Torque reduction resolution on PROFIBUS (LSB weighting)
Default setting: 1 Min. input limit: 0.005 Maximum input limit: 10
Change valid after NEWCONF Protection level: 2/7 Units: %
Data type: DOUBLE Applies from SW version: 2.2
Significance: 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).
Bu changing the torque to 0.005%, for example, you can specify value increments of
0.005%, i.e., the torque limit value is incremented more precisely by a factor of 200.
In this case the value 0 is transferred to limit the value to the rated torque. A full torque
reduction (i.e. without power) is given by the value 10000.
To prevent an incorrect adaptation, the set value of the torque must be selected to match
the interpretation of the torque reduction value configured and defined for the drive.
