18.2.16 LS_MultiEncoder
The LS_MultiEncoder system block provides the speed, position and error information of an SSI
encoder connected to the synchronous-serial interface (SSI) as process signals to the application.
Outputs
Identifier
Data type
Value/meaning
dnPosition_p
DINT
Actual position value from the encoder in [increments]
nActSpeed_v
INT
Actual speed from the encoder in [increments/ms]
nActSpeed_a
INT
Actual speed from the encoder in [%]
• 100 % ≡ reference speed ( C00011 )
wHighWord
wLowWord
WORD
32-bit data telegram from the encoder (raw data)
bFail
BOOL
Status signal "Fault"
TRUE An error has occurred at the encoder interface.

Detailed information on how to parameterise and configure the SSI encoder evaluation
can be found in the main chapter "Motor control (MCTRL)" in the subchapter " SSI encoder
evaluation ". ( 266)
