(2) Spindle axis
[Description]
This function can read the estimate disturbance torque data. The
estimate disturbance torque data is the load torque data except a
necessary torque data for acceleration / deceleration of the spindle
motor. This read value is normalized from –16384 to 16384. The
value 16384 corresponds to the maximum torque of spindle motor.
Applying the following formula to this value, you can determine the
ratio of the estimate disturbance torque to the maximum torque of the
spindle motor.
Ratio (%) = [data] * 100 / 16384
Applying the following formula, you can also determine the estimate
disturbance torque (Nm). About the 30-min rated torque, refer to the
specification document of the motor.
Estimate disturbance torque (Nm) = [data] * N / 16384
N = [The 30-min rated torque of the motor] * 1.2.
