6.1.1 Change function assignment
The internal processing function of the digital input terminals DI1/DI2 and 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 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)
You can find detailed information on the respective function assignment in the following
subchapters:
Using DI1(6) and DI2(7) as digital inputs
( 326)
Using DI1(6) and DI2(7) as frequency inputs
( 327)
Using DI1(6) as counting input
( 332)
C00115/1: Function assignment DI1 and DI2
C00115/2: Function assignment of DI6 and DI7
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
(speed)
Frequency input
(direction)
4 DI1(6)=CountIn / DI2(7)=In Count input Digital input
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 generally designed as "standard" 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).
