Distance 2 from the zero point of the linear scale with absolute addressing refer-
ence marks to the reference position
NOTE
After this parameter is set, the power must be turned off then
back on for the setting to become effective.
[Data type] Word axis
[Unit of data] Detection unit 100,000,000
[Valid data range] –20 to 20
Set the distance from the scale zero point to the reference position. The
reference position is set according to parameter No. 1883 and this
parameter. This parameter is used if the distance from the scale zero point
to the reference position is beyond the setting range of parameter No.
1883.
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).
