A5000: Drive heat sink over-
temperature
The alarm threshold for overtemperature
at the inverter heat sink has been reached.
If the temperature of the heat sink in-
creases by an additional 5 K, then fault
F30004 is initiated.
Check the following:
• Is the surrounding air temperature within
the defined limit values?
• Have the load conditions and the load duty
cycle been appropriately dimensioned?
•
A6310: DC link voltage ex-
ceeding the tolerance range
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.
Check the line supply voltage.
A7012: Motor temperature
model 1/3 overtemperature
The motor temperature model 1/3 identi-
fied that the alarm threshold was exceed-
ed.
• Check the motor load and reduce it if re-
quired.
• Check the motor surrounding air tempera-
A7565: Encoder error in
encoder interface
An encoder error was signaled for encoder
via the encoder interface (G1_ZSW.15).
Acknowledge the encoder error using the en-
coder control word (G1_STW.15 = 1).
A7576: Encoderless opera-
tion due to a fault active
Encoderless operation is active due to a
fault.
• Remove the cause of a possible encoder
fault.
• Carry out a POWER ON (power off/on) for
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
This alarm automatically disappears after the
data has been saved.
A7971: Angular commuta-
tion offset determination
activated
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 alarm automatically disappears after de-
termination.
A7991: Motor data identifica-
tion activated
The motor data identification routine is
activated.
The motor data identification routine is
carried out at the next power-on com-
mand.
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-
A30016: Load supply
switched off
The DC link voltage is too low.
•
Switch on the load supply.
•
Check the line supply if necessary.
