VEO - Velocity Override
or
Function
0 = Override as factor
1 = Override as limit
Override value in ‰ (from 001 to 999)
This value is significant only in mode 4
0 = Read in new override value in each controller cycle
(2 milliseconds)
1 = Read override value only once when command is invoked
Override mode defaults
0 = Override disabled, or as programmed in Parameter AA04
1 = Analog value of 0...+10 volts at analog input
2 = Binary value at inputs I0.00.6 to I0.01.4
3 = Gray code value at inputs I0.00.1 to I0.01.4
4 = Override value from VEO command (see above)
Axis 1
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. A106), and
therefore limits the velocity. Activation of an override function using the
VEO command has priority over activation of any function within
Parameter AA04.
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.
See also Section 8.4 – Velocity Override.
The program proceeds to the next instruction following the time period of
one cycle.
