4.12 Connecting induction motors with TTL encoder (from SW 8.1)
Standard square–wave encoders (TTL) with differential signals accor-
ding to RS422 and 5 V power supply voltage can be connected as
pulse encoder for induction motors to the control board ”SIMODRIVE
611 universal HR” (Order No. 6SN1118–NH01–0AA).
The maximum encoder limiting frequency is 420 kHz.
Encoder connection X411/X412
Pin assignment of the interface:refer to Chapter 2.4
Encoder cable: Users must assemble these themselves
Max. cable length: 50 m
Note
If an induction motor with TTL encoder is connected to ”SIMODRIVE
611 universal HR”, then it is not permissible that the angular
incremental encoder interface is used as output.
!
Warning
If individual or several signals of the encoder are short–circuited or
interrupted – under certain circumstances – it is possible that the
encoder signal monitoring does not respond and the motor can move
in an uncontrolled fashion.
The following parameters are available for connecting an induction
motor with TTL encoder:
P1011 IM configuration, actual value sensing
P1005 IM encoder pulse number
P1027 IM configuration, encoder
