The "Force/torque weighting method" schematic shows the structure with which the acceleration is scaled using the SERCOS wizard. A distinction must be made between linear and rotary weighting in this. In percentage weighting the permanently permissible standstill torque of the motor is used as the reference value. All torque/force data is given in [%] with one decimal place.
Torque polarity:
The polarity of the torque can be inverted according to the application. A positive torque reference indicates clockwise rotation (looking at the motor shaft).

Linear weighting
| Unit | Weighting factor |
Parameter weighting (LSB) |
|---|---|---|
| Nm | 1 | LSB = Unit * Exponent |

Rotary weighting
| Unit | Weighting factor |
Preferential weighting (LSB) |
Parameter weighting (LSB) |
|---|---|---|---|
| Nm | 1 | 0.01 Nm | LSB = Unit * Exponent |
