Analog output
The frequency inverter provides an analog voltage signal
(0 - +10 V) at control signal terminal 18. This signal is factory set
proportional to the output frequency (0 - f
max
). The calibration and
parameterization of the analog output are described in the Section
“Analog output (P4)”, page 83.
Digital inputs
The frequency inverter has six digital inputs (DI1 to DI6) that have
an identical function and operation. Their actuation is factory set
for +24 V (positive logic, source type). You can use the device
internal control voltage of control signal terminal 6 (+24 V,
maximal 50 mA) or an external voltage source (+24 V) with a
residual ripple less than ±5 % DU

/U
a
. The parameterizable
functions are described inSection “Digital input (P3)”, page 78.
The factory set functions and the electrical connection data are
shown in Section “Function of the control signal terminals”,
page 44.
Microswitch S1 (LOGIC) is used to change the control logic to
so-called negative logic (Sink type). The digital inputs are
connected internally or externally via control signal terminal 7
(DI_COM) directly to +24 V and to the corresponding 0V potential
(GND) via the input terminals DI1 to DI6.
