6.2.1.8 Format Signal 11: Position value 1, Sensor 1 (G1_XIST1)
Via signal G1_XIST1 the current incremental actual position of the measuring system is output
unsigned as a right-justified 32-bit binary value. After switching on the supply voltage, the signal
G1_XIST1 is initially assigned the absolute value. Depending on the code sequence, this value is only
incremented or decremented. An overflow is always generated after 32 bits: 0xFFFFFFFF ->
0x00000000. In the default setting, the preset function has no influence on the position output, see
parameter Preset affects XIST1 on Page 47. Depending on the setting of the parameter
Encoder Class 4 functionality, other parameter settings can also directly affect the position
output.

6.2.1.9 Format Signal 12: Position value 2, Sensor 1 (G1_XIST2)
Via signal G1_XIST2 the current scaled absolute actual position of the measuring system is output
unsigned as a right-justified 32-bit binary value. However, the corresponding bits must be set in the
control words:
G1_STW: Bit 13 = 1, STW2_ENC: Bit 10 = 1
The preset function has a direct influence on the position output. Depending on the setting of the
parameter Encoder Class 4 functionality, other parameter settings can also directly affect
the position output.
If a measuring system error is present (G1_ZSW, Bit 15 = 1), instead of the position a 16-bit error code
is transmitted in data bits 2
0
to 2
15
, see Page 71.
The measuring system remains in the error state until the cause of the error has been eliminated and
the error state has been acknowledged with the control word G1_STW Bit 15 = 0->1 edge.

6.2.1.10 Format Signal 39: Position value 3, Sensor 1 (G1_XIST3)
Via signal G1_XIST3 the current scaled absolute actual position of the measuring system is output
unsigned as a right-justified 64-bit binary value. However, only 32-bit is supported at present, Bits 2
32
to 2
63
are therefore set to 0. The preset function has a direct influence on the position output. For
parameter settings to be effective, Class 4 functionality must be enabled under the parameter
Encoder Class 4 functionality, see Page 46.
