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

Note!
• In the Lenze setting of
, the digital input terminals DI1 and DI2 are
configured as "standard" digital inputs.
• The digital input terminals DI3 ... DI5 are generally designed as "standard"
digital inputs.
• If the digital inputs are parameterised as frequency inputs, the corresponding
output signals (

bIn2
) at the
takes the FALSE status.
General information on how to parameterise the speed feedback for the motor
control can be found in the chapter entitled "
