Name Function
Specify the
Axis
axis.
*Note: AXIS_REF_SM3(FB): All function blocks for an axis group contain this variable, which works as the starting program for
function blocks.
Function

This function is available for DL_MotionControl V1.2.0.0 or later.

Absolute position (lrPosition) and modulus (lrModulo) relationship

Absolute position in modulo (lrPosition<lrModulo)

The final positioning is within the modulo.
Absolute position outside the modulo (lrPosition>lrModulo)

The final positioning is outside the modulo, running n times modulo distance.
Direction mode:

Positive－Only allow forward positioning

Absolute position ahead of current position: move forward to the target position of the next modulo.

Absolute position lags behind the current position: move forward to the target position of the next

modulo.
Negative－Only allow reverse positioning

Absolute position ahead of current position: move in reverse to the target position of the modulo.

Absolute position lags behind current position: move in reverse to the target position of the last modulo.

Current－Current motion direction positioning

Currently running forward, absolute position ahead of current position: move forward to the target

position of the next modulo.
Currently running forward, absolute position lags behind current position: move forward to the target

position of the modulo.
Currently running in reverse, absolute position ahead of current position: move in reverse to the target

position of the modulo.
Currently running in reverse, absolute position lags behind current position: move in reverse to the

target position of the last modulo.
Shortest－Shortest distance positioning

Absolute position ahead of the current position for greater than 0.5 modulo: move in reverse to the

target position of the next modulo.
Absolute position ahead of the current position for smaller than 0.5 modulo: move in reverse to the

target position of the modulo.
Absolute position lags behind the current position for greater than 0.5 modulo: move in reverse to the

target position of the last modulo.
