5 Connection of position and speed sensors<br />
5.1 General notes<br />
Depending on module type the <strong>SMX</strong> module (<strong>SMX</strong>11/<strong>SMX</strong>12) has (1/2) external encoder<br />
interfaces <strong>for</strong> the connection of industrial incremental and absolute encoders. The encoder<br />
interfaces can be configured as incremental, SIN/COS, or as absolute SSI-encoders.<br />
It is also possible to connect 2 incremental signal generating sensors (e.g. proximity<br />
switches) to the counting inputs of the <strong>SMX</strong> module. The signals must each be read in with<br />
normal and complementary track.<br />
IMPORTANT<br />
The voltage supply of the encoder system uses the dedicated terminal on the <strong>SMX</strong> module.<br />
This voltage is applied to the encoder plug and monitored by an internal diagnostic process.<br />
When the sensor is supplied with an external voltage, this voltage must be supplied through<br />
the encoder plug. The corresponding terminal (encoder supply voltage) on the <strong>SMX</strong> module<br />
remains unoccupied.<br />
If an external sensor voltage supply is not recirculated through the encoder plug, any failure<br />
of this supply must be included in the fault examination of the overall system. This, in<br />
particular, requires evidence that this fault is detected or can be excluded when the specified<br />
operating voltage of the overall system is fallen short of / exceeded.<br />
EMC - measures such as shielding etc. must be observed.<br />
The two encoders must be non-interacting to each other. This applies <strong>for</strong> both the electrical<br />
as well as the mechanical part.<br />
If both encoders are coupled to the facility to be monitored via common mechanical parts, the<br />
connection must be positively designed and should not have any parts that are susceptible to<br />
wear (chains, toothed belts, etc.). Should this be the case, additional monitoring features <strong>for</strong><br />
the mechanical connection of the sensors (e.g. monitoring of a toothed belt) are required).<br />
In case of an active position processing at least one absolute value encoder must be used.<br />
When using two equivalent sensors one must make sure that the sensor with the higher<br />
resolution is configured as sensor 1 (process sensor) and the sensor with the lower<br />
resolution as sensor 2 (reference sensor).<br />
