HPEHPE
HPE Specifies the actual detection unit for the output of interpolation-type
pitch error compensation, third-dimensional error compensation
interpolation-type straightness compensation, and thermal growth
compensation along tool vector as follows:
0: Detection unit
1: 1/1000 of detection unit (the same unit as for nano interpolation)
NOTE
1 Even when this parameter is set to 1, the measurement unit of
already set compensation data remains to be the detection unit.
So, it is unnecessary to change the compensation data.
2 Even when this function is enabled, the servo output for the
following functions remains to be in the detection unit:Stored
pitch error compensation, gradient compensation, straightness
compensation, and 128-point straightness compensation.
Cautions
CAUTION
1 The thermal growth compensation is not cancelled by
reset of CNC.
2 The amount of the compensation by this function
becomes invalid by the power down of the CNC.
3 In the calculation of the tool direction, calculation for
the rotary axis of the first group is made first, then
based on the calculation result, calculation for the
rotary axis for the second group is made.
4 This function is valid only for the same detection of
basic three axes.
5 The compensation by this function is kept intact even
if an axis is in the servo off by a servo off signal.
When an axis is in the servo off by a servo off signal,
the compensation input by this function is ignored.
6 When the control axis is compensated by this
function, the amount of the compensation is not
reflected in the machine coordinates value.
7 The tool head is supposed to be only one.
(Parallel axes is not available.)
8 Machine Zero Point Shift is available for the same or
different axis when this function is effective.
9 The positions of rotary axes which define the
direction of the tool axis are the positions on the
machine coordinates.
10 The thermal growth along tool axis data and its
compensation for each axis are displayed in
diagnosis screen.
