5.7.4 MVP (move to position)
With this command the motor will be instructed to move to a specified relative or absolute position or a pre-
programmed coordinate. It will use the acceleration/deceleration ramp and the positioning speed
programmed into the unit. This command is non-blocking – that is, a reply will be sent immediately after
command interpretation and initialization of the motion controller. Further commands may follow without
waiting for the motor reaching its end position. The maximum velocity and acceleration are defined by axis
parameters #4 and #5.
Three operation types are available:
Moving to an absolute position in the range from - 8388608 to +8388607 (-2
23
to+2
23
-1).
Starting a relative movement by means of an offset to the actual position. In this case, the new
resulting position value must not exceed the above mentioned limits, too.
Moving the motor to a (previously stored) coordinate (refer to SCO for details).
Please note, that the distance between the actual position and the new one should not be more than
8388607 microsteps. Otherwise the motor will run in the wrong direction for taking a shorter way. If the
value is exactly 8388608 the motor maybe stops.
Internal function: A new position value is transferred to the axis parameter #2 target position”.
