SERCOS interface
6.4 Status messages and warnings
If an error at the SERCOS interface occurs during the startup phase, the
startup of the control (without complete initialization of the SERCOS in-
terface) will be finished. The errors that have occured can then be dis-
played via MODE 7.2 at the PHG or via the ROPS4/Online status.
6.4.1 Status messages at the startup of the SERCOS interface
The following status messages can arise when the SERCOS interface
is initialized:
Sercos-Init-error
(code = 169984)
SERCOS-ASIC cannot be initialized
Check SERCOS hardware
Sercos-Ring open
Phase: 0:
(code = 169088)
The SERCOS ring is not closed
Check SERCOS connections
Sercos error Phase1
axis: x
(code = x − 1)
The indicated axis could not be identified.
x = axis number, e. g. x = 3 means 3rd axis
Check axis addresses (in rho4 and drive ampli-
fier)
Check baud rate
Sercos error Phase2
axis x Y− zzz
(code = 169600)
Sercos-error Phase3
axis x Y− zzz
(code = 169728)
Sercos-error Phase4
axis x Y−
zzz
(code = 169728)
The indicated drive parameter cannot be trans-
mitted owing to an error
x = axis number
Y = SERCOS parameter type
(S = Standard, P= Product specific)
zzz = SERCOS ident. number
Check parameter value
(heed limit values)
Sercos-error Phase2
axis x S− 127
(code = 169600)
Conversion into phase 3 cannot be performed
Check via DSS list of the invalid parameters in
phase 2 (S-0-0021)
Additionally the invalid parameters are displayed
as incorrect
Sercos-error Phase3
axis x S− 128
(code = 169728)
Conversion into phase 4 cannot be performed
Check via DSS list of the invalid parameters in
phase 3 (S-0-0022)
Additionally the invalid parameters are displayed
as incorrect
