For AC/AC drive units, the measured DC
voltage lies outside the tolerance range
after pre-charging has been completed.
The following applies for the tolerance
range: 1.16 * 400 V < actual DC link volt-
age < 1.6 * 400 V.
The alarm can only be eliminated when
the drive is powered down.
The motor temperature model 1/3 identi-
fied that the alarm threshold was exceed-
ed.
An encoder error was signaled for encoder
via the encoder interface (G1_ZSW.15).
Encoderless operation is active due to a
fault.
The angular commutation offset was re-
defined and has still not been saved.
In order to permanently accept the new
value, it must be saved in a non-volatile
fashion.
The automatic determination of the angu-
lar commutation offset (encoder adjust-
ment) is activated.
The automatic determination is carried out
at the next power-on command.
The motor data identification routine is
activated.
The motor data identification routine is
carried out at the next power-on com-
mand.
The DC link voltage is too low.
Hardware current limit for phase U re-
sponded. The pulsing in this phase is
inhibited for one pulse period.
Closed-loop control is incorrectly pa-
•
rameterized.
Fault in the motor or in the power ca-
•
bles.
The power cables exceed the maxi-
•
mum permissible length.
Motor load too high.
•
Power unit defective.
•
Note:
Alarm A30031 is always output if, for a
Power Module, the hardware current limit-
ing of phase U, V or W responds.
Check the line supply voltage.
Check the motor load and reduce it if re-
•
quired.
Check the motor surrounding air tempera-
•
ture.
Acknowledge the encoder error using the en-
coder control word (G1_STW.15 = 1).
Remove the cause of a possible encoder
•
fault.
Carry out a POWER ON (power off/on) for
•
all components.
This alarm automatically disappears after the
data has been saved.
The alarm automatically disappears after de-
termination.
The alarm automatically disappears after the
motor data identification routine has been
successfully completed.
If a POWER ON or a warm restart is performed
with motor data identification selected, the
motor data identification request will be lost. If
motor data identification is required, it will need
to be selected again manually following ramp-
up.
Switch on the load supply.
•
Check the line supply if necessary.
•
Check the motor data. As an alternative, run a
motor data identification.
Check the motor circuit configuration (star-
•
delta).
Check the motor load.
•
Check the power cable connections.
•
Check the power cables for short-circuit or
•
ground fault.
Check the length of the power cables.
