3.9  Customer specific applications 

The goal in the basic philosophy of 

LinMot

® 

 is to be able to cover the broadest range of 

applications simply by configuring the basic system, without special customer specific 
adjustments. In some cases (big series, special system environments) however customer 
specific adjustments can make sense. In these cases the necessary interventions have to 
be carried out by the manufacturer. 
In most cases the customer specific changes will be realized in the software of the 
electronic unit (‘Customized Application Software’). In most cases this will relate to the 
following two requirements: 
 

• 

Additional control functions 

• 

Networking with customer specific bus systems ( CAN-Bus, RS-232)
