What variable did You read out?
usually You should read the NC-Systemdata $AA_IM (MCS) or $AA_IW (WCS). Both variables provide the already modulo calculated position value.

The corresponding data from NCVAR-selector are:

$aa_iw	C[.]	1	SGA	actToolEdgeCenterPos[.]
$aa_im	C[.]	1	SMA	actToolBasePos[.]

hope that helps
