Expanded functions from SW 5.1
The following expanded functionality is provided with the
"SIMODRIVE 611 universal control board for sin/cos 1Vpp encoders:
– Higher internal resolution, interpolation factor 2048 (previously 128)
– Pulse multiplication is possible (doubling) at the angular incre-
mental encoder interface for absolute value encoders
– Pulse multiplication (doubling) and division (1:2, 1:4, 1:8) are
possible at the angular incremental encoder interface, also for
incremental encoders
– From SW 8.1
It is possible to connect standard square–wave encoders (TTL)
with differential signals according to RS422 and 5 V power sup-
ply voltage as pulse encoder for induction motors at the
SIMODRIVE 611 universal HR" control board (Order No.
6SN1118–VNH01–0AAV).
