Error reaction
Possible reason
E27
(0x31B)
(795
d
)
Ambient temperature too high
Motor is stopped by error ramp and
current limitation.
▸
Insufficient device cooling
▸
SD2M with liquid cooling of the power
components: malfunction of internal
fan
E28
(0x31C)
(796
d
)
Power output stage temperature
too high
Motor is stopped by error ramp and
current limitation.
▸
Insufficient cooling of power output
stage (heat sink)
E29
(0x31D)
(797
d
)
Motor load too high (Motor I²t)
Motor is stopped by error ramp and
current limitation.
(1)
▸
Average motor load is too high due to
mechanical problems
▸
Wrong dimensioning of the motor
E30
(0x31E)
(798
d
)
Power output stage load too high
(I²t)
Motor is stopped by error ramp and
current limitation.
(1)
▸
Average load of output stage is too
high due to mechanical problems
▸
Wrong dimensioning of the drive
E31
(0x31F)
(799
d
)
Speed error or slip too high
SERVO/ VECTOR: Drive is limited
by current monitoring via short-cir-
cuit of the motor phases.
(1)
HSPWM: Drive is stopped by error
ramp and current limitation.
▸
Motor is not able to comply with the
set speed (e.g. defective motor, me-
chanical problems, wrong parame-
ters), failure of the measuring system
E33
(0x521)
(1313
d
)
Power supply load monitoring ->
mains voltage too high
Power supply unit will be discon-
nected from mains.
▸
Parameterized mains voltage does
not match the connected voltage
▸
Device connected incorrectly
▸
Heavy fluctuation of the power supply
towards overvoltage
▸
SD2M: Thermo fuse of the varistors
has tripped. The varistor card must
be replaced.
E34
(0x522)
(1314
d
)
Power supply charge monitoring ->
mains voltage too low
Power supply unit will be discon-
nected from mains.
▸
DC link was not precharged to the
minimum voltage level in the set time
period; mains voltage is connected to
the short-circuited DC link
▸
SD2M: Thermo fuse of the varistor
blows. The varistor card must be re-
placed.
E35
(0x523)
(1315
d
)
Error in external power supply unit
Drive is immediately disabled, mo-
tor coasts to standstill.
▸
Error message from external power
supply unit; power supply is switched
off.
E36
(0x524)
(1316
d
)
Encoder 0 monitoring
Motor is stopped by current moni-
toring via short-circuit of the motor
phases.
▸
Connection of encoder 0 is faulty
▸
Broken cable
Ballast circuit load (I²t ballast resis-
tor)
Ballast circuit load due to:
1
I²t
1
Wrong dimensioning, too much en-
ergy supplied to R
Ballast

)
DC converter overload
(only
0362161xy)
Power supply unit will be discon-
nected from mains.
▸
Overload at voltage converter of DC
link
E38
(0x526)
(1318
d
)
Actual speed value greater than
overspeed threshold
Motor is stopped by current moni-
toring via short-circuit of the motor
phases.
(1)
▸
Wrong parameters
▸
Motor connected incorrectly
