Rev.1.09

4.3.4.29

6501h

– Single-turn resolution

Object 6501h can be used to read out the maximum number of increments per
revolution. (Single-turn resolution)

4.3.4.30

6502h

– Number of distinguishable revolutions

Object 6502h can be used to read out the maximum number of distinguishable
revolutions. (Multi-turn resolution)

4.3.4.31

6503h

– Alarms

Object 6503h shows a possible position error (see Table 4.34)

15(MSB) … 1 0(LSB)
Always 0

Bit 0 = 1: Position error
An error has occurred in the sensor. The position value is incorrect.

Table 4.34: 6503h

– Alarms

4.3.4.32

6504h

– Supported alarms

Object 6504h shows the supported alarms. Only the position error is supported,
therefore the value is always 0x0001h.
