The deceleration distance is not kept by the target position/movement distance change
The control is performed according to the selection when having AxisName(AxesGroupName).Pr.OverrunOperation and
reverse rotation permission selection (Options bit5).
■When the reverse rotation is allowed
When "0: Allow" is set to the reverse rotation permission selection (Options bit5), a deceleration stop is performed once
regardless of the AxisName.Pr.OverrunOperation setting. After the deceleration stop is completed, operation is started to the
changed target position.

■When the reverse rotation is not allowed
When "1: Not allow" is set to the reverse rotation permission selection (Options bit5), the axis operates according to the
AxisName.Pr.OverrunOperation setting.
• When "1: ImmediateStop" is set
Deceleration is started, and the axis immediately stops after the warning "Overrun Warning" (warning code: 0D10H) is output
when it reaches the stop address.

• When "2: KeepCurrentAcc" is set
The deceleration is started, and the axis exceeds the stop address and stops. When the axis exceeds the stop address, the
error "Overrun Error" (error code: 1A7EH) is output.However, the operation stops according to the setting of
AxisName.Pr.StopMode_General when the error occurs. To stop the operation with the address which exceeds the stop
address, set "2: KeepCurrentAcc" in AxisName.Pr.StopMode_General.
