### *class* RATranslation

Rocky PrePost Scripting wrapper representing a Translation motion.

Retrieve this specific wrapper after setting the correct motion type on a [`RAMotion`](RAMotion.md#generated.RAMotion). For example:

```python
motions = motion_frame.GetMotions()
motion_1 = motions.New()
motion_1.SetType('Translation')
translation = motion_1.GetTypeObject()

```

**Methods:**

[`GetAcceleration`](#generated.RATranslation.GetAcceleration)(\[unit\])Get the value of "Acceleration".[`GetFinalVelocity`](#generated.RATranslation.GetFinalVelocity)(\[unit\])Get the value of "Final Velocity".[`GetInput`](#generated.RATranslation.GetInput)()Get "Input" as a string.[`GetValidInputValues`](#generated.RATranslation.GetValidInputValues)()Get a list of all possible values for "Input".[`GetVelocity`](#generated.RATranslation.GetVelocity)(\[unit\])Get the value of "Velocity".[`SetAcceleration`](#generated.RATranslation.SetAcceleration)(values\[, unit\])Set the values of "Acceleration".[`SetFinalVelocity`](#generated.RATranslation.SetFinalVelocity)(values\[, unit\])Set the values of "Final Velocity".[`SetInput`](#generated.RATranslation.SetInput)(value)Set the value of "Input".[`SetVelocity`](#generated.RATranslation.SetVelocity)(values\[, unit\])Set the values of "Velocity".<a id="generated.RATranslation.GetAcceleration"></a>

#### GetAcceleration(unit: str | None = None)

Get the value of “Acceleration”.

- **Parameters:****unit** – The unit for the returned values. If no unit is provided, the returned values will be in “m/s2”.

<a id="generated.RATranslation.GetFinalVelocity"></a>

#### GetFinalVelocity(unit: str | None = None)

Get the value of “Final Velocity”.

- **Parameters:****unit** – The unit for the returned values. If no unit is provided, the returned values will be in “m/s”.

<a id="generated.RATranslation.GetInput"></a>

#### GetInput()

Get “Input” as a string.

- **Returns:**The returned value will be one of \[‘fixed\_velocity’, ‘initial\_and\_final\_velocity’, ‘initial\_velocity\_and\_acceleration’\].

<a id="generated.RATranslation.GetValidInputValues"></a>

#### GetValidInputValues()

Get a list of all possible values for “Input”.

- **Returns:**The returned list is \[‘fixed\_velocity’, ‘initial\_and\_final\_velocity’, ‘initial\_velocity\_and\_acceleration’\].

<a id="generated.RATranslation.GetVelocity"></a>

#### GetVelocity(unit: str | None = None)

Get the value of “Velocity”.

- **Parameters:****unit** – The unit for the returned values. If no unit is provided, the returned values will be in “m/s”.

<a id="generated.RATranslation.SetAcceleration"></a>

#### SetAcceleration(values: Sequence\[str | float\], unit: str | None = None)

Set the values of “Acceleration”.

- **Parameters:**
    - **values** – The values to set. The values can be heterogeneous, the element of values can be an expression with input variables or a float. Must have exactly 3 elements.
    - **unit** – The unit for values. If no unit is provided, values is assumed to be in “m/s2”.
- **Raises:****RockyApiError** – If values doesn’t have exactly 3 elements.

<a id="generated.RATranslation.SetFinalVelocity"></a>

#### SetFinalVelocity(values: Sequence\[str | float\], unit: str | None = None)

Set the values of “Final Velocity”.

- **Parameters:**
    - **values** – The values to set. The values can be heterogeneous, the element of values can be an expression with input variables or a float. Must have exactly 3 elements.
    - **unit** – The unit for values. If no unit is provided, values is assumed to be in “m/s”.
- **Raises:****RockyApiError** – If values doesn’t have exactly 3 elements.

<a id="generated.RATranslation.SetInput"></a>

#### SetInput(value: str)

Set the value of “Input”.

- **Parameters:****value** – The value to set. Must be one of \[‘fixed\_velocity’, ‘initial\_and\_final\_velocity’, ‘initial\_velocity\_and\_acceleration’\].
- **Raises:****RockyApiError** – If value is not a valid “Input” option.

<a id="generated.RATranslation.SetVelocity"></a>

#### SetVelocity(values: Sequence\[str | float\], unit: str | None = None)

Set the values of “Velocity”.

- **Parameters:**
    - **values** – The values to set. The values can be heterogeneous, the element of values can be an expression with input variables or a float. Must have exactly 3 elements.
    - **unit** – The unit for values. If no unit is provided, values is assumed to be in “m/s”.
- **Raises:****RockyApiError** – If values doesn’t have exactly 3 elements.
