General procedure
(if the encoder is connected to the digital inputs DI1 and DI2)
1. Define the function of the digital inputs DI1 and DI2 in C00115/1 .
2. Set the encoder increments in C00420/1 .
3. Select "1: Encoder signal FreqIn12" in C00495 .
4. Adapt the filter time of the speed measurement in C00497/1 .
5.10.1 Parameterising digital inputs as encoder inputs
Define the function of the digital inputs DI1 and DI2 in C00115/1 .
To be able to use the digital inputs as encoder inputs, select 2, 3, or 4 (Lenze recommendation: 2) in
C00115/ depending on the input terminals used.

Selection in C00115/1 Function
2: (DI1/DI2)=FreqIn12 (2-track) DI1 and DI2 = 2-track frequency input
• Permits a two-track evaluation of the encoder including correct
detection of the direction of rotation.
3: (DI1/DI2=+-)=FreqIn12 DI1 = 1-track frequency input
DI2 = specification of direction
4: DI1=CountIn1 | DI2=In2 DI1 = counter input
DI2 = digital input

Danger!
For single-track evaluation, make sure that the sign is correctly specified. Otherwise, the
motor may overspeed.

Note!
If the digital inputs are parameterised as encoder inputs, the corresponding output
signals (bIn1/bIn2) at the LS_DigitalInput system block are automatically set to FALSE.

The wiring diagram and assignment of the input terminals are described in the 8400
hardware manual . The hardware manual has been stored in electronic form on the data
carrier supplied with the 8400 controller.
