MLAxisRatedTq
Description
Allows conversion of drive torqueTorque 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).

TorqueTorque 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 | Description |
Actual torque applied by the drive associated to the axis Rated torque = Nominal Drive Current * Torque factor = DRV.ICONT * MOTOR.KT
About SDO
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 details, refer to:
To read/write an SDO object with an index greater than 16#7FFF (32767), the value must be entered in the form The actual units of DRV.ICONT and MOTOR.KT are 1/1000 of the actual values if obtained by SDO. So the formula, if using the SDO values, is: Rated Torque = Torque = (SDO(DRV.ICONT)/1000) * (SDO(MOTOR.KT)/1000) |
