*Commands*
The motor control application has the following command flow:

* Using different EC presentation layers (DSW-516), the application is capable to support different protocols used to communicate with elevator control. It acts as a translator between the external protocol and the internal DSW protocol.
* Commands for normal operation are passed to Master Control (DSW-126). Master Control will send the necessary command(s) to the components of the inverter (DSW-132).
* In case an inverter component detects a problem, it informs the event handler (DSW-202). The event handler decides about the necessary actions, sends commands to Master Control (DSW-126) and to the presentation layer (DSW-516) to inform the superior system about the problem.
* Tests are processed by the Test Executor (DSW-135). Test executor will pass commands to Master Control or directly to the involved components.

*References*
The motor control application has the following reference sources:

* In normal operation, the references are send by elevator control. The references are translated and scaled by presentation layers (DSW-516).
* The received references are passed to the Speed Reference Filter (DSW-457). The speed reference filter provides the speed references every ms in the correct scaling for Speed Control (DSW-185).
* During evacuation and electrical braking, the speed references are generated internally and fed to Speed Control (DSW-185).
