Fault Subfault
Code Designation Response

Code Designation Possible cause Measure
109 DCS alarm Display fault 42 Plausibility fault incorrect
acceleration. The current acceleration ex-
ceeds the configured maximum
acceleration. • Check the configuration
(encoder screen: max. set
speed).
• Analyze the speed/acceler-
ation profile using the
SCOPE function.
43
44 Plausibility fault in encoder
interface (A3401 = en-
coder 1 and A3402 = en-
coder 2). The encoder interface does not
match the configured data • Check encoder type and
configuration (SSI/incre-
mental)
• Check the encoder connec-
tion/wiring
• Check the polarity of the
encoder data
• Check function of the en-
coder
45
46 Voltage supply of encoder
faulty (A3403 = encoder 1
and A3404 = encoder 2). Encoder voltage supply not
within defined range (min.
DC 20 V / max. DC 29 V). • Overload in the supply
voltage of the encoder; in-
ternal polyswitch fuse has
tripped.
• Check supply voltage of
DCS..B option.
47
48 Fault in reference voltage Reference voltage input of the
encoder system is outside of
the defined range
Check the reference voltage
input of the encoder system
49
50 Difference level RS485
driver 1. Fault Faulty "B" or
"Cycle" signal. • No encoder connection.
• Incorrect encoder type con-
nected.
• Check encoder connection.
• Check encoder cabling.
51
52 Difference level RS485
driver 2. Fault Faulty "A" or
"DATA" signal.

54 Difference in incremental
counter

109 DCS alarm Display fault 56 Plausibility fault in encoder
interface (A3401 = en-
coder 1 and A3402 = en-
coder 2) The encoder interface does not
match the configured data • Check encoder type and
configuration (SSI/incre-
mental)
• Check the encoder connec-
tion/wiring
• Check the polarity of the
encoder data
• Check function of the en-
coder
57
58 Plausibility fault SIN/COS
encoder connection. Incorrect encoder type connec-
ted. Check encoder connection
and cabling.
59
60 Plausibility fault in the in-
cremental encoder con-
nection Phase fault of the incremental
or SIN/COS encoder. • Check encoder connection
• Replace defective encoder
61
62
63
64 Plausibility fault - SSI en-
coder connection (master
mode). Connected encoder type does
not correspond to the configur-
ation. • Check configuration.
• Check connected encoder.
65
66 Plausibility fault SSI en-
coder connection (slave
mode). Connected encoder type does
not correspond to the configur-
ation. • Check configuration.
• Check connected encoder.

68 Faulty switching behavior
of the high-side driver
DO0_P. DC 24 V short circuit at digital
output DO0_P (X82:1). Check wiring at digital output.
69
70 Faulty switching behavior
of the low-side driver
DO0_M. DC 0 V short circuit at digital
output DO0_M (X82:2). Check wiring at digital output.
71
72 Faulty switching behavior
of the high-side driver
DO1_P. DC 24 V short circuit at digital
output DO1_P (X82:3). Check wiring at digital output.
