■Function description

• This FB changes the target velocity and the acceleration/deceleration of the specified axis.

• The target velocity and the acceleration/deceleration are changed to the value obtained by the multiplication of the velocity

in operation by the override factor.

• The FB is executed when Enable is TRUE. Enabled turns TRUE while the override factor is valid.

• If the override factor value is changed while Enable is TRUE, the new override factor is reflected.

• When an error has occurred in the FB, this FB turns Error to TRUE and stores an error code in ErrorID. For details of error

codes, refer to the following.

Page 534 List of Error Codes

• When 0.00 is set to the velocity override factor, the axis stops without changing the axis status to "4: Standstill".

• When 0.00 is set to the acceleration override factor, the acceleration override factor is not changed, and the previous

acceleration override factor is maintained.

This FB changes AxisName.Cd.VelocityOverride and AxisName.Cd.AccelerationOverride.
