4.5 Switch output voltages
For each EtherCAT P port the output voltages U
S
and U
P
can be switched individually.
Protective functions [
}
30] can prevent the switching-on of the output voltages.
A switched-on output voltage is signaled in two ways:
• Status LEDs [ } 24]
• Status bits in the process data:
„DPO Inputs Channel n“ > „Status“ > „Status Us“
„DPO Inputs Channel n“ > „Status“ > „Status Up“
(where: n = 0 for X52, n = 1 for X53, n = 2 for X54, n = 3 for X55)
The output variable "DPO Outputs Device" > "Enable Control Via Fieldbus" defines whether the output
voltages are switched manually or automatically.
• „0“: automatic (factory setting)
• „1“: manual
Inadvertent switching of output voltages.
If you change the value of "Enable Control Via Fieldbus", it is possible that the output voltages may
be switched on or off.
To prevent that, match the values of the CoE indices (automatic switching) and output variables
(manual switching) mentioned below to each other before changing the value of "Enable Control Via
Fieldbus".
Automatic switching
You can specify whether the output voltages are automatically switched on after application of the supply
voltage U
S
.
The following table shows the correlation of the output voltages and the CoE indices that control the
automatic switch-on.
EtherCAT P port Output voltage CoE Index Name
X52 U
S
8000:02 „DPO Settings Ch. 1“ > „Default State Us“
U
P
8000:03 „DPO Settings Ch. 1“ > „Default State Up“
X53 U
S
8010:02 „DPO Settings Ch. 2“ > „Default State Us“
U
P
8010:03 „DPO Settings Ch. 2“ > „Default State Up“
X54 U
S
8020:02 „DPO Settings Ch. 3“ > „Default State Us“
U
P
8020:03 „DPO Settings Ch. 3“ > „Default State Up“
X55 U
S
8030:02 „DPO Settings Ch. 4“ > „Default State Us“
U
P
8030:03 „DPO Settings Ch. 4“ > „Default State Up“
Value range:
• „1“: U
S
/U
P
is switched on automatically when U
S
is applied (factory setting).
• „0“: U
S
/U
P
remains switched off when U
S
is applied.
The output voltages are switched on with a time offset. The time offset prevents the starting currents of the
connected EtherCAT P devices adding together.
You can set the time offset in the CoE index F80E:11 "Startup Delay":
• „0“: „Fast“
• „1“: „Moderate“
• „2“: „Slow“
