SPLDMT Spindle load torque monitor function
0 : The spindle load torque monitor function is disabled.
1 : The spindle load torque monitor function is enabled.
4247 Magnetic flux compensation time constant for spindle load torque monitor
[Data type] Word axis
[Unitofdata] 1msec
[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.
4249 Observer gain 1 for spindle load torque monitor
[Data type] Word axis
[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
4341 Threshold for abnormal load detection alarm
[Data type] Word axis
[Unitofdata] 0.01 %
[Valid data range] 0 to 10000
This parameter specifies the threshold load torque at which an abnormal
load detection alarm is issued for the spindle. Set a percentage (in units of
0.01 %) for the maximum output torque of the motor. When 0 is set, no
abnormal load detection alarm is issued for the spindle.
