8.4 Velocity Override
The override function permits an infinitely variable reduction in the
currently programmed velocity in Manual and Automatic Modes
(exception: homing).
Override via Analog Input
The override is controlled by applying a voltage to E1 (X3/12 and X3/13).
The graph below shows the relationship between the applied voltage and
the override factor.

Fig. 8-14: Analog Override
The velocity `Vo´ is produced by multiplying the programmed traversing
velocity `Vp´ by the override factor `F´ (F = 0 - 1 corresponds to 0V - 10V):
Vo Vp F
= ×
L: Vo = velocity
Vp = Traversing Velocity
F = override factor
Fig. 8-15: Velocity Calculation with Override
This function can be activated in Parameter AA04 or using the VEO
command.
If a voltage = 0V is applied, the E-0100, velocity = 0 diagnostic warning
message is generated.
