HANDBOOK 13. Maintenance
Error Meaning Possible cause
KEB ERROR 31 EOP
Error overvoltage.
Displayed advertisement : - Voltage in the DC-link circuit too high. - Poor controller adjustment
(overshooting), input voltage too
high, interference voltages at
the input, deceleration ramp too
short, braking resistor defective
or too small.
KEB ERROR 32 EUP
Error underpotential.
Displayed advertisement : - Occurs, if DC-link voltage falls below the permissi-
ble value.
- Input voltage too low or ins-
table, inverter rating too small,
voltage losses through wrong
cabling, the supply voltage
through generator/transformer
breaks down at very short ramps,
E.UP is also displayed if no com-
munication takes place between
power circuit and control card,
jump factor (Pn.56) too small, if
a digital input was programmed
as external error input with error
message E.UP (Pn.65).
KEB ERROR 33 EUPH
Error phase failure.
Displayed advertisement : - One phase of the input voltage is missing (ripple-
detection).
.
KEB ERROR 34 EOC
Error overcurrent.
Displayed advertisement : - Occurs, if the specifi ed peak current is exceeded. - Acceleration ramps too short,
the load is too big at turned off
acceleration stop and turned off
constant current limit, short-cir-
cuit at the output, ground fault,
deceleration ramp too short,
motor cable too long, EMC, DC
brake at high ratings active.
KEB ERROR 36 EOHI
Error overheat internal.
Displayed advertisement : - Overheating in the interior : error can only be reset
at E.nOHI, if the interior temperature has dropped
by at least 3°C.
.
KEB ERROR 37 ENOHI
No Error overheat internal.
Displayed advertisement : - No longer overheating in the interior E.OHI, interior
temperature has fallen by at least 3°C.
.
KEB ERROR 38 EOH
Error overheat pow. mod.
Displayed advertisement : - Overtemperature of power module. Error can only
be reset at E.nOH.
- Insuffi cient air fl ow at the heat
sink (soiled), ambient tempera-
ture too high, ventilator clogged.
KEB ERROR 39 EDOH
Error drive overheat.
Displayed advertisement : - Overtemperature of motor PTC. Error can only be
reset at E.ndOH, if PTC is again low-resistance.
- Resistance at the terminals
T1/T2>1650 Ohm, motor over-
loaded, line breakage to the
temperature sensor.
