6.1.1 Change function assignment
The internal processing function of the digital input terminals DI1/DI2 und DI6/DI7 can be
reconfigured in C00115
if necessary. In this way, these input terminals can alternatively be
used as frequency or counting inputs in order to implement the following functions:
 Detection of the input frequency
 Detection and conditioning of two unipolar input frequencies to form one bipolar
frequency
 Counting of input pulses
 Evaluation of the speed feedback (HTL encoder) for the motor control (speed-controlled
operation)
You can find detailed information on the respective function assignment in the following
subchapters:

Function assignment
DI1 / DI6 DI2 / DI7
0 DI1(6)=In / DI2(7)=In Digital input Digital input
1 DI1(6)=FreqIn / DI2(7)=In Frequency input Digital input
2 DI1(6)&DI2(7)=FreqIn (2-track) Frequency input (2-track)
3 DI1(6)=FreqIn / DI2(7)=direction Frequency input

4 DI1(6)=CountIn / DI2(7)=In Count input Digital input
 Note!
• In the Lenze setting of C00115, the digital input terminals DI1/DI2 und DI6/
DI7 have been configured as "normal" digital inputs.
• The digital input terminals DI3 ... DI5 are basically designed as "normal"
digital inputs.
• Very high pulse frequencies can be measured at the DI1/DI2 and DI6/DI7
input terminals if the latter have been configured as frequency or counting
inputs in C00115
. Scanning is then carried out within less than μs instead of
the otherwise usual scanning rate of 1 kHz (1 ms).
