Change function assignment

The internal processing function of the digital input terminals DI1/DI2 und DI6/DI7 can be
reconfigured in
used as frequency or counting inputs in order to implement the following functions:
 Detection of the input frequency
 Detection and processing of two unipolar input frequencies to one bipolar frequency
 Counting of input pulses
 Evaluation of the speed feedback (HTL encoder) for the motor control (speed-controlled
operation)
C00115/1: Function assignment of DI1 and DI2
C00115/2: Function assignment of DI6 and DI7
0 DI1(6)=In / DI2(7)=In
1 DI1(6)=FreqIn / DI2(7)=In
2 DI1(6)&DI2(7)=FreqIn (2-track)
3 DI1(6)=FreqIn / DI2(7)=direction
4 DI1(6)=CountIn / DI2(7)=In

Note!
• In the Lenze setting of C00115, the digital input terminals DI1/DI2 and
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).
You can find detailed information on the respective function assignment in the following
