 FunctionClosed A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Allows conversion of drive torqueClosed Torque is the tendency of a force to rotate an object about an axis. Just as a force is a push or a pull, a torque can be thought of as a twist values from rated torque units
(1000 = rated motor continuous torque) to N.m (Newton meter).

N.m (Newton meter)

No default

Actual torque applied by the drive associated to the axis.

Rated torque = Nominal Drive Current * Torque factor = DRV.ICONT * MOTOR.KT.

DRV.ICONT is obtained by SDO parameter: index 5083h (sub-index 0).

MOTOR.KT is obtained by SDO parameter: index 3593h (sub-index 0).

For more information, see:

  • Communication SDOs
  • Manufacturer specific SDOs
  • Profile specific SDOs

To read/write an SDO object with an index greater than 16#7FFF (32767), the value must be entered in this form:
any_to_int(index # in hex format).

Example: any_to_int(16#8321).

  • The actual units of DRV.ICONT and MOTOR.KT are 1/1000 of the actual values if obtained by SDO.
  • The formula, if using the SDO values, is:
    • Rated Torque = Torque = (SDO(DRV.ICONT)/1000) * (SDO(MOTOR.KT)/1000).
