Output Description

DONE

Data_Type	Default_Value	Range	Unit
BOOL	-	TRUE / FALSE	-

Output DONE indicates the state of execution.

It has the value TRUE when the execution is finished and the outputs are valid. When DONE becomes FALSE other outputs are not valid any more.

ERR

Data_Type	Default_Value	Range	Unit
BOOL	-	TRUE / FALSE	-

Output ERR indicates whether an error occurred during Function Block execution.

It is only valid when DONE is TRUE. The kind of occurred error is specified by the error identifier at output ERNO.

ERNO

Data_Type	Default_Value	Range	Unit
WORD	-	0 … 65535	-

At output ERNO the identifier of an occurred error is provided. It is only valid when DONE and ERR is TRUE. (see, error messages): Error Messages of the Function Block Libraries

RDY_SET   BOOL \   (ready \ set start)

When the action of SET_START finishes, RDY_SET is set to TRUE for only one cycle.

RDY_CALIB   BOOL \   (ready \ calibration)

The output RDY_CALIB displays the ready message of the calibrating process. While input EN_CALIB is set to TRUE, RDY_CALIB = TRUE.

If EN_CALIB = TRUE and rising edge is detected at Z_PULSE signal, RDY_CALIB will be set to TRUE until EN_CALIB = FALSE.

RDY_SYNC   BOOL \   (ready \ synchronisation)

The output RDY_SYNC displays the ready message of the synchronisation process. It is set to TRUE only for one cycle.

Z_PULSE   BOOL \   (input \ signal Z)

The output Z_PULSE indicates that encoder’s reference point Z has been reached. This signal is only visible if programs execution time is slower than the signal of encoder’s reference point (Z).
