4. DESCRIPTION OF PARAMETERS
87
Example: Assume that the following settings have been made. If an
abnormal load is detected for the first axis, movement along
the first, third, and fourth axes is stopped. If an abnormal load
is detected for the second axis, movement along the second
and fourth axes is stopped.
Parameter No.1881 Setting
(First axis) 1
(Second axis) 2
(Third axis) 1
(Fourth axis) 0
NOTE
This parameter is enabled when the ANA parameter (bit 5 of
parameter No.1804) is 1.
1885 Maximum allowable value for total travel during torque control
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter sets the maximum allowable value for the total travel
(error counter value) for an axis placed under torque control, as specified
by the axis control command of the PMC axis control function. If the total
travel exceeds the parameter–set value while torque control is applied, a
servo alarm (No.423) is generated.
NOTE
This parameter is enabled when the TQF parameter (bit 4 of
parameter No.1803) is 0 (follow–up is not performed during
torque control).
1886 Positional deviation when torque control is canceled
[Data type] Word axis
[Unit of data] Detection unit
[Valid data range] 0 to 32767
This parameter sets the positional deviation used when torque control,
performed for an axis according to the axis control command of the PMC
axis control function, is canceled and position control is resumed. After
the positional deviation has fallen to the parameter–set value, switching to
position control is performed.
NOTE
This parameter is enabled when the TQF parameter (bit 4 of
parameter No.1803) is 0 (follow–up is not performed during
torque control).
