Code Designation Possible cause Measure
109 DCS alarm Display fault 74 Faulty switching behavior
of the low-side driver
DO1_M. DC 0 V short circuit at digital
output DO1_M (X82:4). Check wiring at digital output.
75
76 CCW and CW monitoring
of DMC safety function ac-
tivated simultaneously. Multiple activation of the DMC
safety function. Make sure to activate only
one "enable" in the control of
the DMC safety function.
77
78 CCW and CW monitoring
range of the OLC safety
function activated simul-
taneously. Multiple activation of the OLC
safety function. Make sure to activate only
one "enable" in the control of
the OLC safety function.
79
80 CCW and CW monitoring
of JSS safety function acti-
vated simultaneously. Multiple activation of the JSS
safety function. Make sure to activate only
one "enable" in the control of
the JSS safety function.
81
82 Timeout fault MET. Input element with time monit-
oring is faulty. Check input element wiring.
83
84 Timeout fault MEZ. Two-hand control with time
monitoring is faulty. Check input element wiring.
85
86 EMU1 monitoring fault. • Faulty output control
• Faulty feedback Check wiring at digital output.
87
88 EMU2 monitoring fault
89
90 Plausibility fault position
changeover. Position changeover during
ZSC, JSS or DMC is perman-
ently activated. • Check ZSC (SOS) activa-
tion.
• Check JSS (SDI) activation.
• Check DMC (SDI) activa-
tion only for monitoring the
position.
91
109 DCS alarm Display fault 92 SSI encoder fault. Encoder step SSI value within
one cycle is too large. • Check encoder configura-
tion.
• Check encoder cabling.
93
94 SSI encoder fault. Plausibility fault for position ad-
justment. • Check encoder configura-
tion.
• Check encoder cabling.
95
96 Plausibility fault of incre-
mental encoder tracks. • Different counting signals on
A/B encoder tracks.
• Defective component at
RS485 interface.
• Encoder operates outside
tolerances of encoder inter-
face.
• Check encoder configura-
tion.
• Check encoder cabling.
• Check encoder signal
levels.
• Check maximum counting
frequency of incremental
encoder.
97
98 Plausibility fault analog/di-
gital comparison at
Schmitt trigger output –
encoder input X84. • Connected encoder type
does not correspond to the
configuration.
• Faulty encoder signals
• Hardware defective
• Check configuration.
• Check connected encoder.
• Replace DCS..B option.
• Send faulty DCS..B option
with fault number to
SEW‑EURODRIVE for fault
diagnostics.
99
100 Plausibility fault analog/di-
gital comparison at
Schmitt trigger output –
encoder input X85. • Connected encoder type
does not correspond to the
configuration.
• Faulty encoder signals
• Hardware defective
• Check configuration.
• Check connected encoder.
• Replace DCS..B option.
• Send faulty DCS..B option
with fault number to
SEW‑EURODRIVE for fault
diagnostics.
101
110 Position processing range
check for DCS22B/32B. Position processing activated
for DCS22B/32B options. • Check configuration data.
• Deactivate position pro-
cessing.
111
112 Faulty OSSD input check. Faulty OSSD test. • Check DC 24 V input
voltage of all OSSD inputs.
• Switch DCS..B option off
and on again.
