MODABS

MODABS 1:

The MODABS function carries out a modulo division and determines the unsigned modulo value within the modulo range.

Examples

MODABS( 400.56, 360) = 40.56

MODABS( -400.56, 360) = 319,44

Similar functions: MOD, LMOD

Note: The MODABS function can be used to calculate the modulo set position of an NC axis from its absolute set position.

ModuloSetPosition := MODABS( NcToPlc.fPosSoll, 360 );
