Encoder/Feedback System - Lenze L-force HighLine C 8400 Series Reference Manual

5.11

Encoder/feedback system

For the motor controls with speed monitoring the feedback signal can be supplied via an
HTL encoder at the digital input terminals (DI1/DI2 or DI6/DI7).

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. 100 kHz
– DI6/DI7: 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.
