ABNTDT
[Data type] Bit axis
ABNTDT Output of the estimated load torque (for each axis)
0 : Disabled
1 : Enabled
This parameter must be specified when using the estimated load torque
output function or the abnormal load detection alarm function.
2050 Velocity control observer
[Data type] Word axis
[Valid data range] 0 to 32767
[Setting value] 3559
When using the velocity loop observer (by setting bit 2 of parameter No.
2003 to 1), set 956 in this parameter.
2051 Velocity control observer
[Data type] Word axis
[Valid data range] 0 to 32767
[Setting value] 3329
When using the velocity loop observer (by setting bit 2 of parameter No.
2003 to 1), set 510 in this parameter.
2103 Retraction distance upon the detection of an abnormal load
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter specifies the distance by which the tool is to be retracted,
by reversing the motor, if an abnormal load is detected. When the motor is
rotating at low speed, however, the tool may be retracted too far. To
prevent this, the motor is stopped, instead of being reversed, while the
specified feedrate is less than the value listed in the table below.
When this parameter is set to value A, the detection of an abnormal load
causes the tool to be retracted in the reverse direction by the distance A,
then stopped, if the specified feedrate is equal to or greater than the value
listed below.
Detection unit Feedrate
1m
0.1m
A / 8 mm/ min
A / 80 mm/ min
When this parameter is set to 0, the motor stops immediately upon the
detection of abnormal load.
