Code Error message Error reaction Possible reason
E30
(0x31E)
(798d)
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)
(799d)
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)
(1313d)
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)
(1314d)
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)
(1315d)
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.
See chapter 16.2 “List of the Power
Supply Error Messages”, page 165.
E36
(0x524)
(1316d)
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
, broken ca-
ble, no bridge at R
Ballast
(int./ext.)
E37
(0x525)
(1317d)
2 (VCE) desaturation detection
or: DC/DC converter overload
(only 0362144xy)
Drive is immediately disabled, mo-
tor coasts to standstill.
2 Bridge at R
Ballast
is not correct,
short circuit of insulation etc.
Or: internal hardware fault (only
0362144xy)
E37
(0x525)
(1317d)
DC converter overload (only
0362161xy)
Power supply unit will be discon-
nected from mains.
▸
Overload at voltage converter of DC
link
E38
(0x526)
(1318d)
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
E39
(0x527)
(1319d)
Tracking error monitoring and mo-
tor slowdown
Motor is stopped by current moni-
toring via short-circuit of the motor
phases.
(1)
▸
Wrong parameters
▸
Motor connected incorrectly
▸
Mechanical problems
E40
(0x528)
(1320d)
Motor feedback Motor is stopped by current moni-
toring via short-circuit of the motor
phases.
(1)
▸
Connection of motor feedback faulty
▸
Broken cable
Motor phase lost Motor connection/configuration is faulty:
1 No motor connected 1 No motor connected / incorrect
wiring, broken cable
E41
(0x529)
(1321d)
2 Wrong motor connected
Motor is stopped by current moni-
toring via short-circuit of the motor
phases.
(1)
2 Wrong parameters
E42
(0x52A)
(1322d)
Overvoltage in DC link Drive is immediately disabled, mo-
tor coasts to standstill.
▸
No ballast resistor is connected or
ballast resistor is dimensioned too
small, i.e. X41/X63 not connected
