connected which is stored in the encoder evaluation and which is completely
known.
If ec17 only contains the manufacturer name (e.g. 76 "BISS Mode Hengstler, Sin-
gleturn" or 77 "BISS Mode Hengstler, Multiturn"), the encoder evaluation could
read a manufacturer ID from the encoder without knowing the exact encoder type.
The values of 74 and 75 "BiSS Mode C, singleturn or multiturn, + EDS type label"
indicate that the manufacturer identification is unknown, but the encoder contains
an el. nameplate, which corresponds to the BiSS profile BP3.
Values 61 and 62 "BiSS Mode C, singleturn or multiturn" (i.e. without el. name-
plate) mean that the encoder does not allow memory access or it is a BiSS-C unidi-
rectional variant.
If value 84 "BiSS Mode C, EDS containing inconsistent data" is displayed, the en-
coder has an electrical nameplate, but the data does not correspond to the profile
definition or they are inconsistent.
In this case, the values must be set as for BiSS-C unidirectional encoders, be-
cause it cannot be ensured that the values from the encoder are correct.
The display of the manufacturer name in ec17 means, encoders of this manufac-
turer have already been tested. However, it is recommended to test actual encod-
ers again.
BiSS linear encoders:
Only linear encoders with BiSS-C unidirectional are supported.
➢ Linear measuring devices
Different linear encoders are supported:
- EnDat: absolute linear encoders
- BiSS-C, but only unidirectional, i.e. without electronic nameplate
- SSI
- Incremental linear encoders with 1Vpp or square-wave signals, with periodic, dis-
tance-coded or without reference marks.
For more information on linear encoders, see 6.1.7, "Operation of absolute linear
encoders“, page 251 and 6.1.8 "Operation of non-absolute linear encoders (with
and without reference marks))“, page 254)
6.1.2.4 List with tested encoders
The following list contains a selection of tested absolute encoders with different
protocols and interfaces. "Standard" incremental encoders with SinCos, TTL or
HTL signals are not listed:
