Fault Subfault
Code Designation Response
(P)
Code Designation Possible cause Measure
82 Open output Immediate
stop 0 Output open with "VFC
hoist" Only in "VFC hoist" mode:
• Two or all output phases are
interrupted.
• Nominal motor power too
small in relation to rated in-
verter power
• Check connection between
inverter and motor
• Check startup data and per-
form new startup, if neces-
sary.
84 Motor protec-
tion Emergency
stop (P) 0 "Motor temperature emula-
tion" fault • Motor utilization too high.
• I
N
-U
L
monitoring triggered
• P530 set later to "KTY"
• The motor must cool off,
then reset the fault
• Reduce load
• Extend ramps
• Observe longer pause
times
• Check P345/346
• Select a larger motor
2 Temperature sensor wire
break
3 No thermal motor model
available
4 UL monitoring fault
11 Temperature sensor short
circuit
86 Memory
module Immediate
stop 0 Fault in connection with
memory module • No memory card
• Memory card defective • Tighten knurled screw
• Insert and secure memory
card
• Replace memory card
• Load delivery status and
parameter set
87 Technology
function Immediate
stop 0 Technology function selec-
ted with standard unit A technology function was acti-
vated in a standard device Disable technology function
88 Flying start Immediate
stop 0 "Flying start" fault Only in VFC n-CTRL operating
mode:
Actual speed > 6000 rpm when
inverter enabled Only enable a actual speed
≤ 6000 min

92 DIP encoder
problem Fault display
(P) 1 Stahl WCS3 dirt problem Encoder signals a fault Possible cause: Encoder is
dirty → clean encoder
93 DIP encoder
fault Emergency
stop (P) 0 "Absolute encoder" fault The encoder signals a fault,
e.g. power failure
• Connection cable between
the encoder and DIP11B
does not meet the require-
ments (twisted pair, shielded)
• Clock frequency too high for
cable length
• Permitted max. speed/accel-
eration of encoder exceeded
• Encoder defective
• Check absolute encoder
connection
• Check connection cables
• Set correct clock frequency
• Reduce maximum travel
speed or ramp
• Replacing absolute en-
coders.
94 EEPROM
checksum Immediate
stop 0 Power section parameters Inverter electronics disrupted.
Possibly due to EMC influence
or defect.
Sending in a device for repair
5 Control unit data
6 Power section data
7 Invalid version of the con-
figuration data set
95 DIP plausibil-
ity fault Emergency
stop (P) 0 Plausibility monitoring of
absolute position No plausible position could be
determined
• Incorrect encoder type set
• IPOS
PLUS®
travel parameter
set incorrectly
• Numerator/denominator
factor set incorrectly
• Zero adjustment performed
• Encoder defective
• Set the correct encoder
type
• Check IPOS
PLUS®
travel pa-
rameters.
• Check travel speed.
• Correct numerator/denom-
inator factor
• Reset after zero adjustment
• Replacing absolute en-
coders.
97 Copy fault Immediate
stop 0 Parameter set upload is/
was faulty • Memory card cannot be writ-
ten or read
• Fault during data transmis-
sion
• Repeat copying process
• Restore delivery state
(P802) and repeat copying
process
1 Download of parameter
set to unit canceled.
