24 Vdc power supply, ±8 %
Capacity: 500 mA
Note: In the models with the 24 Vdc external control power supply
(CFW11...O...W...) pin 13 o XC1 is considered na input, that is, the user
must provide a supply for the inverter (for further details refer to
Item 7.2.1
Use of External Dynamic Braking Module DBW03 and DBW04 on page
7-4
). In all the other models this terminal is an output, i.e., the user has a
24 Vdc power supply available there
