The following encoder types are supported:
S
Incremental encoder with sin/cos 1Vpp
S
Absolute value encoder with EnDat protocol and incremental tracks
with sin/cos 1Vpp
S
Resolver with pole pair numbers 1 to 6 and 1 to 64 from SW 7.1 with
"SIMODRIVE 611 universal HR"
S
Incremental encoders with TTL signal from SW 8.1 mounted on in-
duction motors – only with "SIMODRIVE 611 universal HR" (Order
No. 6SN1118–VNH01–0AAV)
From SW 6.1 for "SIMODRIVE 611 universal HR", it is possible to set
the resolver resolution.
S
Resolver resolution: 14 bit
– P1011.2=1 (indirect measuring system)
– P1030.2=1 (direct measuring system)
S
Resolver resolution: 12 bit
– P1011.2=0 (indirect measuring system)
– P1030.2=0 (direct measuring system)
Fault message 749 (from SW 7.1) is output, if the following conditions
are not fulfilled:
S
A 14–bit resolution was set for "SIMODRIVE 611 universal" ––>
only a 12–bit resolution is possible
S

––> (max. encoder frequency/resolver pole pair number
> P1147
S
Induction motor (ARM):

––> (max. encoder frequency/resolver pole pair number
> min (P1146, P1465)
S
Max. encoder frequency:
––> 12 bit: 432 Hz
––> 14 bit: 108 Hz
