Writing the User Program CLM01.4-LAP-01VRS
DOK-CONTRL-CLM01.4LAP1-FK01-EN-P
This command produces a reduction in the velocity of all of the
programmed traversing commands.
With the ‘Override as factor’ function, the override value is multiplied by
the programmed velocity from the commands.
With the ‘Override as limit' function, the override value is multiplied by the
programmed velocity from the parameter Vmax (Param. Ax06), and
therefore limits the velocity. Activation of an override function using the
VEO command has priority over activation of any function within
Parameter B017.
Once a 'VEO' command has been invoked, it applies to all subsequent
motions until it is canceled. See also the examples on the following
pages.
Any change in operating mode between ‘Automatic’ and ‘Manual' cancels
the override function invoked by the 'VEO' command. The values can be
changed again in Task 3.
The program proceeds to the next instruction following the time period of
one cycle.
Description of Override Mode 5 ( in Preparation)
This function can only be activated using the 'VEO' command if the axis is
designated as a 'Normal Axis' in Parameter Ax00.
Additionally, Master
Encoder 1 must be set up correctly in the parameters (Parameter C000,
C001 and C002).
Otherwise, the program proceeds to the following
instruction immediately.

The maximum velocity is taken from Parameter Ax06.
The multiplier is always equal to 1 after each restart or error
acknowledgement, or after termination of Parameter Mode.
If the axis reaches a velocity of more than 1.25 times Vmax (Parameter
Ax06), because of a programming error or excessive velocity of the
measuring wheel encoder, the error message ` max. Override Ax´ is
issued.
However, the velocity of the drive is limited to Vmax in any case, for
measuring wheel encoder speeds > Vmax.
