Note
You can disable automatic adjustment via:
• MD13070 $MN_DRIVE_FUNCTION_MASK[n], Bit 15 = 0
Manual parameterization
If any of the aforementioned requirements for automatic adjustment is not met, the NC
machine data and drive parameters must be adjusted manually.
● MD37620 $MA_PROFIBUS_TORQUE_RED_RESOL = drive parameter: "Torque
reduction evaluation"
Example for SIMODRIVE 611U
Assumptions:
● Machine axis X1 corresponds to drive 12A
● The torque reduction evaluation is to be 0.1%
Assigning parameters for the DP slave 611U/Drive 12A
SimoCom U commissioning tool: Menu command Commission > Other parameters > Expert
List > Number > 881
Torque reduction: P0881 = 1638.40 (≙ 0.1%)
The parameter is immediately effective.
