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

PROFIBUS_TORQUE_RED_RESOL
torque reduction resolution on PROFIBUS (LSB weighting)
min. input limit: 0.01
Protection level: 2 / 7
For the drives connected via PROFIBUS, the MD defines the resolution of the torque re-
duction transferred in the cyclic SIMODRIVE standard message frames 102 to 107 (control
word: TorRed). The torque reduction is e.g. required as part of the function "Travel to fixed
stop" (FXST).
At automatic adjustment, the machine data must be set so that it is consistent with the
meaning of drive parameter P0881: "Torque reduction evaluation"; or with manual adjust-
ment with the drive-end interpretation of the control word: TorRed.
The default value of 1% corresponds to the resolution that was valid prior to SW 2.2.
