Multi-Encoder Connection; Topline C Control Terminals - Lenze 8400 Hardware Manual

Multi-encoder connection

Encoders are connected at X8 (15-pole Sub-D socket).
In order to avoid interference injections, only use shielded motor and encoder cables when
using an encoder.
Absolute and incremental encoders are supported:
ƒ
– TTL encoders 5 V (incremental)
– SinCos encoders 1 V
– SinCos absolute value encoders 1 V
– SSI absolute value encoders with Stegmann protocol
Improved detection of low speeds with TTL encoders by additional time measuring
ƒ
technique.
SinCos absolute value encoders are read out serially during initialisation (connection
ƒ
of the supply voltage). Then the SinCos signals are evaluated.
Open-circuit monitoring:
ƒ
– In the case of SinCos encoders by comparison of the SinCos signals with the
sine-wave form (radius monitoring)
– In the case of TTL encoders by monitoring of the mean value and the amplitudes
– Not with SSI encoders
The following is not supported:
ƒ
– HTL encoders -
they are not connected via the multi-encoder input, but via the digital inputs of
the controller.
– Motors with an installed ENP and KTY -
for these motors, correct temperature evaluation and motor protection are not
possible with 8400.
