SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Setting parameters for the SINUMERIK 840Di NC
Enter value 0.1 in the axis-specific machine data of machine axis X1
S
MD 37620: PROFIBUS_TORQUE_RED_RESOL (torque reduction resolu-
tion on PROFIBUS (LSB weighting)).
The machine data is effective after NC reset (warm restart).

Boundary conditions
Notice
It is the start-up engineer’s responsibility to ensure that the parameter settings
are consistent in the SINUMERIK 840Di NC and all relevant drives for which
torque reduction is being performed.
The following data must be consistent in terms of values and meaning:
1. SINUMERIK 840Di NC machine data
MD 37620: PROFIBUS_TORQUE_RED_RESOL (torque reduction resolu-
tion on PROFIBUS (LSB weighting))
2. Drive
With automatic adjustment:
Parameter P0881 torque reduction evaluation
With manual adjustment:
The parameter corresponding in meaning to the DP slave 611U: pa-
rameter P0881.
Notice
If automatic adjustment cannot be performed by the SINUMERIK 840Di NC
due to requirements that are not met, of if the drive returns a value for parame-
ter P0881 that lies beyond the NC machine data limit values, or if the torque
reduction is not rescaled on the NC end, no alarm is issued. The machine data
S
MD 37620: PROFIBUS_TORQUE_RED_RESOL (torque reduction resolu-
tion on PROFIBUS (LSB weighting))
is effective in all cases independently.
