- What does the term "NRND" present by some controllers on the maxon website mean in practice?
- How long will a controller be still available if it is marked as NRND?
"NRND" means that ...
- ... a controller is not recommended for the development of new machines or devices based on it. (NRND stands for is "Not recommended for new designs".)
- ... a controller was developed a long time ago (i.e. often more than 10 years ago) and it is at the end of its so-called product life cycle.
- ... there are newer and more state-of-the-art maxon controllers present with a similar and often more enhanced feature set and performance. These new controllers should be used for new projects and the development of new machines and devices.
- ... there will be no more firmware, software, driver, or manual updates available for this controller in future anymore.
- ... such controllers will not be present within the maxon catalog anymore, i.e. there will be no more marketing activities for these controllers.
"NRND" does NOT(!!) mean that such a product will be canceled soon.
- The controller in NRND state is still available, it can be ordered, and it is still produced in series. Typically the controller is available on stock (even in high quantities).
- Support and repair services is still ensured.
- All the data sheets, manuals, and software can be downloaded by the corresponding maxon product website.
Typically there is a time gap of about five years in between a product's initial NRND state and the end of production. Anyway it is even possible that it will be extended up to 10 years (or even more) if the ordered quantities are still high and all components are available. It is impossible to provide a guaranteed figure about this period in advance. All mentioned periods are based on some practical experience during the last years.
There are mainly two influencing factors about the decision when production will be finally stopped:
- Market demands
As long as there is a market demand (by all customers) of more than 500 .... 1000 pcs. of a specific controller per year present, it will still be produced (if all components are available). Quite often there have been more than 10000 or 100000 pcs. of a controller type shipped within its product life cycle. These controllers are in use by machines and devices which may be still produced and sold by maxon customers. Finally the market requests is one criteria if the effort and increasing costs of an "old" controller's low volume production is still competitive or it will be more efficient to switch to a new controller type (e.g. EPOS2 -> EPOS4).
- Availability of components
A "killing" criteria which finally triggers end of production are specific components (e.g. processors) which are not available anymore and the component stock is also gone. maxon has a professional product and obsolescence management team which tracks the information of component manufacturers and availability of components on a regular base. This prevents from getting trapped by "suddenly" not available components which would result in a hard stop of a controller's production without any chance to build up some stock or investigate in alternative solutions.
maxon's professional product management
maxon has a professional product management team which monitors the market requests for each controller type and the availability of components permanently during any state of a product's life cycle. This team identifies varying market requests and checks component's availability or cancellation. This is the base to identify possible strategies or inform frequent customers about a planned end of production before this actually happens. There are typically at least 6 months left for users to decide about a final last-time buy or prepare the replacement with a new controller.
maxon's customer information service
If a maxon controller is canceled (i.e. production will be stopped within the next months), direct maxon customers will be informed in case they have bought this controller type regularly in the past. The situation and long-term demand forecast can be discussed with maxon's sales engineer and product management team to find a suitable solution. There is the chance for a final last-time buy to satisfy the long-term demand of the concrete application and expected field service requests. It is recommended to investigate in a new controller as a replacement again and verify its functionality for the concrete application by tests.
