Parameterising digital inputs as encoder inputs
The function of the digital inputs DI1/DI2 and DI6/DI7 is defined via
.
To be able to use the digital inputs as encoder inputs, select 2, 3, or 4 (Lenze recommendation: 2) in
, depending on the input terminals used.

Function
2: DI1(6)&DI2(7)=FreqIn (2-track)
DI1/6 and DI2/7 = 2-track frequency input
• Permits a two-track evaluation of the encoder including correct
detection of the direction of rotation.
3: DI1(6)=FreqIn / DI2(7)=Direction
DI1/6 = 1-track frequency input
DI2/7 = specification of direction
4: DI1(6)=CountIn / DI2(7)=In
DI1/6 = counter input
DI2/7 = 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 and bIn6/bIn7) at the
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.
