Id=0x1: The 'operating status error sources' displays an multiturn error 1. Arg='OpStatErrSrc'

Bit 10: MPos1 : An M Pos 1 error message signals that the multiturn scanning or processing of the multiturn position has failed during encoder operation. The multiturn part of the transferred position value is not reliable under these conditions. Corrective measure: The consistency of the revolution counter value must be checked. If this is not possible, the axis must be referenced.
Bit 11: MPos2
Bit 12: MSystem : An M System error message signals that a multiturn-related internal error during the initialization phase of the encoder has occurred. The multiturn part of the transferred position value is not reliable under these conditions. Corrective measure: The power-on cycle should be repeated. If this also fails, a hardware problem of the encoder is probable. The consistency of the revolution counter value must also be checked.
Bit 13: MPowerFailure : The M Power failure error message signalizes that both the voltage of the buffer battery (UBAT) and the main supply voltage (UP) have fallen below the defined limit values. The subsequent electronics can only read out this error message when the main voltage supply has been restored. The multiturn part of the transferred position value is not defined and therefore faulty. During the M Power failure state there is no revolution counting. The possibly simultaneously occurring error messages M Pos 1, M System and M Overflow are to be ignored. Corrective measure: The axis must be referenced again.
Bit 14: MOverflow : The M Overflow error message signals that the specified (multiturn) counting range of the encoder has been exceeded. The encoder remains fully functional. M Overflow error messages can only be cleared when the multiturn value is again in the specified counting range. Corrective measure: Bring the axis into the specified counting range of the encoder again and clear error messages according to the EnDat specification.
