STS_CMP1 0 A comparison of the register contents has produced the
following result: (REG_SSI_POS)
≠
(REG_CMP1)
1 A comparison of the register contents has produced the
following result: (REG_ SSI_POS) = (REG_CMP1)
STS_STOP 0 The SSI encoder is read cyclically.
1 Communication with the SSI encoder is stopped as STOP = 1
(process output) or ERR_PARA = 1.
ERR_PARA 0 The parameter set of the module has been accepted.
1 Operation of the module is not possible with the present
parameter set.
STS_UFLW 0 A comparison of the register contents has produced the
following result: (REG_SSI_POS)
≧ (REG_LOWER_LIMIT)
1 A comparison of the register contents has produced the
following result: (REG_SSI_POS) < (REG_LOWER_LIMIT)
STS_OFLW 0 A comparison of the register contents has produced the
following result: (REG_SSI_POS)
≦ (REG_UPPER_LIMIT)
1 A comparison of the register contents has produced the
following result: (REG_SSI_POS) > (REG_UPPER_LIMIT)
ERR_SSI 0 SSI encoder signal present.
1 SSI encoder signal faulty. (e.g. due to a cable break).
SSI_DIAG 0 No enabled status signal is active (SSI_STSx = 0).
1 At least one enabled status signal is active (SSI_STSx = 1).
