6.1.1

Configuring DI1 and DI2 as frequency inputs

This function extension is available from version 02.00.00!

The internal processing function of the digital input terminals DI1 and DI2 can be reconfigured in

C00115/1

if required. This serves to use these input terminals optionally as frequency inputs to im-

plement the following functions:

• Detection of the input frequency
• Detection and processing of two unipolar input frequencies to one bipolar frequency
• Evaluation of the speed feedback for the

V/f control (VFCplus + encoder)

Note!

• In the Lenze setting of

C00115/1

, the digital input terminals DI1 and DI2 are config-

ured as "standard" digital inputs.

• The digital input terminals DI3 ... DI8 are basically designed as "normal" digital inputs.
• If the digital inputs are parameterised as frequency inputs, the corresponding output

signals (bIn1/bIn2) at the

LS_DigitalInput

system block automatically takes the FALSE

status.

Detailed information on how to parameterise the speed feedback for the motor control

can be found in the chapter entitled "

Encoder/feedback system

".
