connected correctly
• Short circuit / broken wire in
encoder cable
• Encoder defective
• EMC interference
• Check encoder cable and
shield for correct connec-
tion and broken wire
• Replace encoder
• Providing for EMC meas-

(P) 0 Invalid control word IPOS Only in IPOS
PLUS®
mode:
• Attempt was made to set an
invalid automatic mode (via
external control)
• P916 = BUS RAMP is set
• Check serial connection to
external controller
• Check write values of ex-
ternal controller
• Set correct value for P916
78 IPOS SW
limit switch No response
(P) 0 Software limit switch hit Only in IPOS
PLUS®
mode:
Programmed target position is
outside travel range delimited
by software limit switches
• Check user program
• Check position of the soft-
ware limit switches
79 Hardware
configuration Immediate
stop 0 Deviating hardware config-
uration when replacing the
memory card The following values no longer
match after memory card re-
placement:
• Power
• Nominal voltage
• Variant ID
• Device family
• Design as Technology/
Standard unit
• Option cards
Ensure identical hardware or
restore delivery state (para-
meter = factory setting)
80 RAM test Immediate
stop 0 "RAM test" fault Internal device fault, RAM de-
fective. Consult SEW Service
81 Start condi-
tion Immediate
stop 0 Start condition fault with
VFC hoist Only in "VFC hoist" mode:
The motor could not be sup-
plied with the correct amount of
current during the pre-magnet-
izing time:
• Nominal motor power too
small in relation to rated in-
verter power
• Motor cable cross section too
small.
Only for operation with a linear
motor (as of firmware 18):
• The drive has been set to
"Enable" although the com-
mutation offset between lin-
ear motor and linear encoder
is not known. This means
that the inverter cannot set
the current indicator cor-
rectly.
• Check startup data and per-
form new startup, if neces-
sary.
• Check connection between
inverter and motor
• Check cross section of mo-
tor cable and increase if ne-
cessary
• Perform commutation travel
in the "No enable" state and
then switch to "Enable"
once the inverter has ac-
knowledged in status word
bit 25 that commutation
was successful.
