14 = field current not zero
15 =
armature current not zero
armature voltage measurement circuit open (e.g. not connected) or interrupted, check also current and torque
limits
armature circuit and/or armature voltage measurement circuit wrongly connected
no load connected to armature circuit
invalid nominal armature current setting;
− armature current M1MotNomCur (99.03) is set to zero
field current does not decrease when the excitation is switched off
field current actual doesn't reach field current reference;
− no detection of field resistance;
− field circuit open (e.g. not connected) respectively interrupted
no writing of control parameters of speed controller
tacho adjustment faulty or not OK or the tacho voltage is too high during autotuning
tuning of speed controller, speed feedback assistant or tacho fine tuning not possible due to speed limitation - see
e.g. M1SpeedMin (20.01) and M1SpeedMax (20.02)
Tuning of speed controller, speed feedback assistant or tacho fine tuning not possible due to voltage limitation.
During the tuning of the speed controller, the speed feedback assistant or the tacho fine-tuning base speed
[M1BaseSpeed (99.04)] might be reached. Thus full armature voltage [M1NomVolt (99.02)] is necessary. In case
the mains voltage is too low to provide for the needed armature voltage the autotuning procedure is canceled.
Check and adapt if needed:
− Mains voltage
− M1NomVolt (99.02)
− M1BaseSpeed (99.04)
field weakening not allowed, see M1SpeedFbSel (50.03) and FldCtrlMode (44.01)
discontinuous current limit could not be determined due to low current limitation in M1CurLimBrdg1 (20.12) or
M1CurLimBrdg2 (20.13)

no field exciter selected, see M1UsedFexType (99.12)

1 = DCS Control Panel up- or download not started
DCS Control Panel data not up- or downloaded in time
reserved
DCS Control Panel up -or download checksum faulty
DCS Control Panel up- or download software faulty
DCS Control Panel up- or download verification failed

The flash is written to cyclic by AP (e.g. block ParWrite). Cyclic saving of values in the flash will damage it! Do not
write cyclic on the flash!
-49 reserved
parameter flash faulty (erase)
parameter flash faulty (program)
check connector X12 on SDCS-CON-F and connector X12 and X22 on SDCS-PIN-F
-69 reserved
(alarm parameter setting conflict):
reserved
flux linearization parameters not consistent
wrong firing angle limitation (Max and Min value 20.14 and 20.15)
armature data not consistent.
Check if:
− M1NomCur (99.03) is set to zero,
− M1NomVolt (99.02) and M1NomCur (99.03) are fitting with the drive. In case they are much smaller than the
drive the internal calculation of M1ArmL (43.09) and M1ArmR (43.10) can cause an internal overflow. Set
M1ArmL (43.09) and M1ArmR (43.10) to zero.
For M1ArmL (43.09) following limitation is valid:
