ITelescopeV3AxisRates(TelescopeAxes)Exceptions| Exception | Condition |

| DriverException | An error occurred that is not described by one of the more specific ASCOM exceptions. The device did not successfully complete the request. |
Remarks
See the description of MoveAxis(TelescopeAxes, Double) for more information. This method must return an empty collection if MoveAxis(TelescopeAxes, Double) is not supported.
This is only available for telescope InterfaceVersions 2 and later
Please note that the rate objects must contain absolute non-negative values only. Applications determine the direction by applying a positive or negative sign to the rates provided. This obviates the need for the driver to present a duplicate set of negative rates as well as the positive rates.
