Encoder/feedback system
For motor control with speed feedback, the feedback signal can be fed to the digital terminals
(DI1/DI2) via an HTL encoder.
[5-15] Signal flow - encoder interface
How to get to the parameterisation dialog of the encoder/feedback system:
1. In the »Engineer«, go to Project view and select the 8400 controller.
2. Select the Application parameters tab from the Workspace.
3. Click the following button of the Overview dialog level:
4. Go to the Overview Motor data dialog level and click the Encoder/Feedback system...
button.
Danger!
• To avoid interference 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
Note!
In the Lenze setting (e.g. when the device is delivered), the open-circuit monitoring of the
encoder is activated.
Encoder open-circuit monitoring
Wiring diagram, assignment and electrical data of the digital input terminals can be
found in the 8400 protec 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.
