Encoder/Feedback System - Lenze 8400 StateLine C Reference Manual

5.10

Encoder/feedback system

For the motor control modes with speed feedback, the feedback signal can be supplied at
the digital input terminals (DI1/DI2) via an HTL encoder.

Danger!
• In order to prevent interference injections when using an encoder, only use
shielded motor and encoder cables.
• If an HTL encoder is used at the digital input terminals:
Observe the maximum input frequencies of the digital inputs!
– DI1/DI2: max. 10 kHz

Note!
In the Lenze setting (e.g. when the device is delivered), the open-circuit
monitoring of the encoder is activated.


Wiring diagram, assignment and electrical data of the digital input terminals
can be found in the 8400 hardware manual in the chapter "Technical data".
• The hardware manual has been stored in electronic form on the data carrier
supplied with the 8400 drive controller.
