2104 Threshold for abnormal load detection alarm
[Data type] Word axis
[Unit of data] Torque command unit (Refer to the digital servo operator’s manual for
details.)
[Valid data range] 0 to 7282
(The maximum motor torque is 7282, regardless of the motor type.)
This parameter specifies the threshold load torque at which an abnormal
load detection alarm is issued.
Monitor the load torque by setting bit 5 of parameter No. 2015 to 1 then,
for this parameter (No. 2104), set a value larger than the maximum
monitored torque. An output of 4.4 V is equivalent to 7282 in the units of
this parameter.

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
[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.
