AGND
(24 V)
Reference (0 V) for the
analog outputs Connected to the ground (frame) through impedance: 940 Ω resistor
in parallel with a 22 nF capacitor
11 DGND*
Reference (0 V) for the
24 Vdc power supply Connected to the ground (frame) through impedance: 940 Ω resistor
in parallel with a 22 nF capacitor
12 COM
Common point of the digital
inputs
13 24 Vcc
24 Vdc power supply 24 Vdc power supply, ±8 %
Capacity: 500 mA
Note: in the models with the 24 Vdc external control power supply
(CFW11XXXXXOW) the terminal 13 of XC1 becomes an input, i.e., the user
must connect a 24 Vdc power supply for the inverter (refer to the
Item 7.1.2
Safety Stop Function on page 7-2 , for more details). Inall the other models
this terminal is an output, i.e., the user has a 24 Vdc power supply available
there

Figure 3.41: Signals of connector XC1 - Digital inputs as active low
NOTE!
In order to use the digital inputs as active low, it is necessary to remove the jumper between XC1: 11
and 12 and change it to XC1: 12 and 13.
