Cause
Intermediate circuit DC
voltage is oscillating due to
missing input power line
phase or blown fuse.
Incorrect input power and
motor cable connection.
Excessive intermediate cir-
cuit DC voltage.
Intermediate circuit DC
voltage is not sufficient.
Difference in DC voltages
between parallel-connected
inverter modules.
Motor circuit fault due to
missing motor connection
(any of the three phases not
connected). In scalar control
mode, the drive detects fault
only when the output fre-
quency is above 10% of the
motor nominal frequency.
Connect motor cable. If the
drive is in scalar mode and
nominal current of the motor
is less than 1/6 of the nom-
inal output current of the
drive, set parameter 31.19
Motor phase loss to No ac-
tion [0].
Control board temperature
is too high.
What to do
Check input power line fuses and
there is no input power supply imbal-
ance.
Check input power connections.
Check overvoltage control is on, sup-
ply voltage matches the nominal input
voltage of the drive. Check supply line
for static or transient overvoltage,
brake chopper, brake resistor and
deceleration time. Use coast-to-stop
function (if applicable).
Check supply cabling, fuses and
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.
If the drive is in scalar mode and
nominal current of the motor is less
than 1/6 of the nominal output current
of the drive, set parameter 31.19 Mo-
tor phase loss to No action [0].
Check proper cooling of the drive and
auxiliary cooling fan.
