IAxisRates
Collection of IRate rate objects
Exceptions
ExceptionCondition
InvalidValueExceptionIf an invalid Axis is specified.
NotConnectedExceptionIf the device is not connected
DriverExceptionAn error occurred that is not described by one of the more specific ASCOM exceptions. Include sufficient detail in the message text to enable the issue to be accurately diagnosed by someone other than yourself.
Remarks

Must be implemented, must not throw a MethodNotImplementedException.

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 to present a duplicate set of negative rates as well as the positive rates.
