Description
This parameter is the torque constant of the motor in Nm/A.The value can be online checked according to the following equation:
Kt = 60 *√3 * Ui/( 2 * π* n)
Where:
Ui = induced voltage of the motor
n = actual rotor velocity
-
- This parameter is automatically configured for Kollmorgen motors when AXIS#.MOTOR.AUTOSET = 1 and can be modified while AXIS#.MOTOR.AUTOSET = 1 if its AXIS#.MOTOR.DISAUTOSET index = 1.
