DI5 as frequency input

For setting the parameters for the digital frequency input, see ACH580 HVAC control
program firmware manual (3AXD50000027537 [English]).

DI6 as PTC input

If DI6 is used as a PTC input, see ACH580 HVAC control program firmware manual
(3AXD50000027537 [English]) for how to set parameters accordingly.
Note: If DI6 is used as PTC input, the wiring and the PTC sensor need to be double
isolated. Otherwise the CMOD-02 I/O extension module must be used.

1 One to six PTC thermistors connected in series.

AI1 and AI2 as Pt100, Pt1000, Ni1000, KTY83 and KTY84 sensor inputs (X1)

One, two or three Pt100 sensors; one, two or three Pt1000 sensors; or one Ni1000,
KTY83 or KTY84 sensor for motor temperature measurement can be connected between
an analog input and output as shown below. Do not connect both ends of the cable
shields directly to ground. If a capacitor cannot be used at one end, leave that end of
the shield unconnected.
