EL5032-0090 - TwinSAFE SC process data

The EL5032-0090 transmits the following process data to the TwinSAFE logic:

The position value "Position (uint32)" (0x60n0:12) of channels 1 and 2 is thereby transmitted by default.

The process data for the individual channels can be deselected on the "Process Image" tab in the Safety Editor.

If the ModuleIdent 0x010013A8 is selected, the "Velocity" can additionally be selected in the Safety Editor in the required data type.

Use of EnDat 2.2 encoders with position values >32 bits ULINT values cannot be processed in the TwinSAFE logic, therefore there is no possibility to transmit the position value 0x60n0:11 "Position" to the TwinSAFE logic. In this case the process data must be parameterized under 0x8021 "TSC Process Data settings".

Parameterization of the TSC process data

Since ULINT values cannot be processed in the TwinSAFE logic, it may be necessary to parameterize the TwinSAFE SC process data when using EnDat 2.2 encoders that transmit a position value of > 32 bits. The parameterization of the process data and their effect must be taken into account accordingly in the safety application, especially with regard to counter/position value overflow.

The parameterization is done under 0x8021 "TSC Process Data Settings". In the process, the number of position bits is automatically read from the EnDat protocol and can be taken from the object 0x90n8:51 "Clock pulse periods".

• 0x8021:0n: Auto align to MSB Ch.n
• Default: the bit is not set.
  The position value is shifted to the right by the number of bits in 0x8021:1n "Shift right data Ch.n".
• If the bit is set the position value is automatically shifted to the right to the max. MSB.
• 0x8021:1n: Shift right data Ch.n
• Default: 0
  The position value is shifted by 0 bits to the right.
• An individual number of bits can be specified by which the process data is to be shifted to the right.
