4247 Magnetic flux compensation time constant for spindle load torque monitor
[Data type] Word axis
[Unit of data] 1 msec
[Valid data range] 0 to 8192
[Standard setting] Depends of the motor model.
This parameter is used to compensate the delay in the generation of
magnetic flux in the spindle motor relative to the specified value. When 0
is set, it is assumed that the generation of magnetic flux is not delayed.
4248 Spindle load torque monitor constant
[Data type] Word axis
[Valid data range] 0 to 32767
[Standard setting] Depends of the motor model.
This constant is determined by the maximum output torque and inertia of
the motor. It is used for observer processing.

[Valid data range] 0 to 32767
[Standard setting] 500
4250 Observer gain 2 for spindle load torque monitor
[Data type] Word axis
[Valid data range] 0 to 32767
[Standard setting] 500
