1. Outline
This function enables to execute the external machine coordinate system shift for 8 axes
within 8 msec interval by extending the current external machine coordinate system shift
function. As for the PMC interface, R address area, which is set by parameter, is used
instead of G address (G000 – G002). The compensation value is specified by a binary
code ranging from –32767 to 32767 and it is absolute value.
It enables to multiply the compensation value of the external machine coordinate system
shift and magnification for each axis together.
(2)
By this, the shift range of compensation of the external machine coordinate system shift is
extended.
The maximum change value in every 8 msec is +-127. And if the pitch error compensation
and so on are effective, the maximum change value is +-127 including the pitch error
compensation value.

(2) When this function is effective ( parameter No.1203#0 = 1 ), normal external machine coordinate system shift becomes invalid. (3) If the R address area, which does not exist, is set, th
