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
circuit DC voltage.
Intermediate circuit DC
voltage is not sufficient.
Difference in DC voltages
between parallel-connec-
ted inverter modules.
What to do
Check input power line fuses and
there is no input power supply im-
balance.
Check input power connections.
Check overvoltage control is on,
supply 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 applic-
able).
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).
