2.1.7 Time Designation Positioning (MVT)

! Outline

The time designation positioning (MVT) command limits the axis feed speed so that each

axis moves from the current position to the end position with the positioning (MOV)

motion, and completes the positioning in the designated time. Because this command is

not the interpolation motion command, there is no guarantee that all designated axes can

complete the positioning simultaneously. A time lag exists, depending on the accel/decel

setting. Up to 14 axes can be designated simultaneously. An axis which is not designated

does not move.

! Detailed Explanation

The designating method of the MVT command is shown as follows:

• Positioning cannot be completed in the designated time when using override.

• When using filter, positioning time delays the amount of filter time constant.
