2310 Overcurrent
EN
HI
Cause
Output current has ex-
ceeded internal fault limit.
In addition to an actual
overcurrent situation, this
fault may also be caused
by an earth fault or supply
phase loss.
What to do
Check the auxiliary code (format
XXXYYYZZ):
"ZZ" indicates the overcurrent type
and phase that triggered the fault:
bit 7 =1 indicates SW overcurrent
bit 0: Phase U
bit 1: Phase V
bit 2: Phase W
For example: Aux code 0x83 indic-
ates SW overcurrent of phase U and
V. If there is no aux code, this indic-
ates that hardware overcurrent is
triggered.
Check motor load.
Check acceleration times in para-
meter group 23 Speed reference
ramp (speed control), 26 Torque
reference chain (torque control) or
28 Frequency reference chain (fre-
quency control). Also check para-
meters 46.01 Speed scaling, 46.02
Frequency scaling and 46.03 Torque
scaling.
Check motor and motor cable (in-
cluding phasing and delta/star
connection).
Check there are no contactors
opening and closing in motor cable.
Check that the start-up data in
parameter group 99 corresponds
to the motor rating plate.
Check that there are no power
factor correction capacitors or
surge absorbers in motor cable.
Check for an earth fault in motor or
motor cables by measuring the in-
sulation resistances of motor and
motor cable. See chapter Electrical
installation, section Checking the
insulation of the assembly in the
Hardware manual of the drive.
