5.8.1 Parameterising digital inputs as encoder inputs
The function of the digital inputs DI1/DI2 is defined in C00115/1 .
To be able to use the digital inputs as encoder inputs, select 2, 3 or 4 (Lenze recommendation: 2) in
C00115/1 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 = 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 the assignment of the input terminals can be found in the 8400
protec hardware manual.
