Feedback bits Notes
ERR_24V Short circuit of the encoder supply
The error bit must be acknowledged by the EXTF_ACK control bit.
Diagnostic message if assigned.
ERR_DO1 Short circuit/wire break/overtemperature at output DO1
The error bit must be acknowledged by the EXTF_ACK control bit.
Diagnostic message if assigned.
ERR_LOAD Load function error
The LOAD_VAL, LOAD_PREPARE, C_DOPARAM, and C_INTTIME bits cannot be set
simultaneously during transfer. This results in setting the ERR_LOAD status bit, similar to loading an
incorrect value (which is not accepted).
ERR_PARA Parameter assignment error ERR_PARA
RES_STS_A Resetting of status bits active
STS_C_DN Down direction status
STS_C_UP Up direction status
STS_CMP1 Measurement completed
After every elapsed time interval (update time/integration time), the measured value is
updated.
Measurement with integration time
The end of a measurement (after the interval has elapsed) is indicated with the STS_CMP1 status
bit.
Continuous measurement
At the end of the update time, the end of the measurement is signaled with status bit STS_CMP1 if a
measured value is output. The bit remains 0 if an estimated measured value is output.
This bit is reset by the RES_STS control bit in the control interface.
STS_DI DI status
The status of the DI is indicated in all modes with the STS_DI bit in the feedback interface.
STS_DO1 DO1 status
STS_GATE Internal gate status: Measuring
STS_LOAD Load function is running
STS_OFLW High measuring limit violated
STS_UFLW Low measuring limit violated
Both bits must be reset.
