Installation manual 4.2 Safety related characteristic data and wiring for the connected sensors The SMX100 modules have completely separated signal processing paths for each safety input.

Installation manual 5.11 Connection of position and speed sensors 5.11.1 General notes Depending on the module type, SMX100 axis expansion module (SMX121, SMX121-2, SMX122, SMX122-2) has external encoder interface (2/4) to connection conventional incremental and absolute encoders. The encoder interfaces can be configured as incremental, SIN/COS, absolute SSI encoder or as Proxy.
Page 139
Installation manual In Slave-mode the clock signal is generated by an external process and is read in by the SMX 100 module together with the data signal. This type of reading causes a beat which results in a reading fault of the following magnitude: F = (reading time of encoder by external system [ms] / 8 [ms] ) * 100 % The size of the resulting reading fault F must be taken into account when determining the thresholds in the applied monitoring functions, because this fault cannot be compensated!

Installation manual Applicative measure: By linking within the PLC program, activation of the outputs with time bypass of the alarm state is prevented. Example 1: The enable function of the outputs (ID 88) is additionally linked with a "reset timer".
