(4) Malfunction
In case of a malfunction of overcurrent protection and current limitation, each output voltage is protected by a
short-circuit protection. The short-circuit protection is dimensioned such that it only becomes active if the
overcurrent protection and current limitation fail.
As a last resort, each output voltage is protected by a fuse. If the fuse has blown the box is defective. The
fuse specifications can be found in the chapter
Resetting an error state
If an output voltage has been switched off by the overcurrent protection, it can be activated again through
one of the following actions:
• a positive edge on the output variables
"DPO Inputs Channel n" > "Reset Ux" of the respective EtherCAT P port
(n = 0 for X52, n = 1 for X53, n = 2 for X54, n = 3 for X55)
• a positive edge on the output variables
„DPO Outputs Device“ > „Global Reset“
The error message is also reset as a result.
4.3.2
Overcurrent protection for sum currents
EP9224-0037 determines two types of sum currents:
• Sum current for each individual EtherCAT P port (calculated)
U
S
+ U
P
• Sum current for all EtherCAT P ports (measured)
∑ (U
S
+ U
P)
The overcurrent protection for sum currents is deactivated in the factory settings. It can be individually
activated and parameterized for each sum current.
