Machine axis X1:
S MD37620: $MA_PROFIBUS_TORQUE_RED_RESOL == 0.1
18.3.7 Constraints
No message is displayed in the following cases:
S If any of the requirements are not met, no automatic adjustment can be per-
formed for the SINUMERIK 840Di sl NCK.
S The parameter assigned in the drive for the torque reduction evaluation lies
outside of the NCK machine data limit values.
S The torque reduction is not renormalized for the NCK.
Irrespective of whether or not a message is displayed, the following NCK ma-
chine data is effective in all cases:
S MD37620: $MA_PROFIBUS_TORQUE_RED_RESOL
Notice
It is the commissioning engineer’s responsibility to ensure that the parameter
settings are consistent in the SINUMERIK 840Di sl NCK 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 sl NCK machine data
MD37620: $MA_PROFIBUS_TORQUE_RED_RESOL
2. Drive
S Automatic adjustment:
Parameter for torque reduction evaluation:
– SINAMICS: p1544
– SIMODRIVE: P0881
S Manual adjustment:
Drive parameter for torque reduction evaluation.
