Cause
Intermediate circuit DC voltage is not
sufficient because of a missing supply
phase, blown fuse or fault in the
rectifier bridge.
Automatic restart failed (see section
Automatic restart (page
Difference in DC voltages between
parallel-connected inverter modules.
Motor circuit fault due to missing
motor connection (all three phases are
not connected).
Autophasing routine (see section
Autophasing (page 102)) has failed.
Estimated and measured positions
have opposite signs.
Motor is rotating during
autophasing.
What to do
Check brake chopper and resistor (if
present).
Check deceleration time.
Use coast-to-stop function (if
applicable).
Retrofit drive with brake chopper and
brake resistor.
With parallel-connected modules,
check the auxiliary code (format XXXY
YYZZ).
"Y YY" specifies through which BCU
control unit channel the fault was
received.
Check supply cabling, fuses and
switchgear.
With parallel-connected modules,
check the auxiliary code (format XXXY
YYZZ).
"Y YY" specifies through which BCU
control unit channel the fault was
received.
Check the condition of the supply
119)). (voltage, cabling, fuses, switchgear).
Check the auxiliary code (format XXXY
YYZZ). "XXX" specifies the source of
the first error (see "YYY"). "YYY"
specifies the module through which
BCU control unit channel the fault was
received (1: Channel 1, 2: Channel 2, 4:
Channel 3, 8: Channel 4, ..., 800:
Channel 12).
Connect motor cable.
For more information, check the
auxiliary code.
Check that the motor ID run has been
successfully completed.
Clear parameter
user.
Check the setting of parameter
Motor type.
Check the signs of measured and
estimated speeds.
Reverse encoder cable phasing or
edit parameter 99.16.
Check that the load torque is not
too high for the Turning mode (must
be less than 5%).
Check that the motor is not already
rotating when the autophasing
routine starts.
