This section introduces the causes of some common alarms and their solutions.
Number

Alarm
code
Possible causes
Solutions
1.
Drive short circuit
0x2250
1.
Short circuit exists in the U, V
and W outputs of the drive
2.
The report is wrong due to
that the drive is disturbed in
the following cases:
1) The ground wire is not
well connected;
2) Inappropriate settings of
the
parameters
of
the
current loop regulator lead
to current oscillation and
interference;
3) The internal circuit of the
drive is abnormal;
3.
The drive is damaged (e.g.
IGBT short circuit, abnormal
current detection circuit)
1.
Check the wiring of the
drive's U, V and W phases
(for
example,
observe
whether the drive is still
reporting short-circuit alarm
after the disconnection of
the motor's power cable, but
this operation shall be done
when the motor brake is in
braking state to ensure
mechanical safety)
2.
Ensure
standard
wiring,
especially the ground wire
3.
Adjust the parameters of the
current loop
4.
Use a multimeter to check
the drive IGBT to determine
if there if a short circuit
5.
Replace the drive
2.
Continuous
over
current Phase U
0x2310
1.
There is a short-circuit in the
drive's U phase
2.
The motor is overloaded
3.
The motor insulation is poor
4.
The drive is damaged
5.
The parameters of the
current loop regulator are
improperly set
1.
Check the wiring of the U
phase
2.
Reduce the motor load
3.
Measure
the
motor
insulation, and repair or
replace it when necessary
4.
Repair or replace the drive
5.
Adjust the parameters of the
current loop regulator
3.
Continuous
over
current Phase V
0x2311
1.
There is a short-circuit in the
drive's V phase
2.
The motor is overloaded
3.
The motor insulation is poor
4.
The drive is damaged
5.
The parameters of the
current loop regulator are
improperly set
1.
Check the wiring of the V
phase
2.
Reduce the motor load
3.
Measure
the
motor
insulation, and repair or
replace it when necessary
4.
Repair or replace the drive
5.
Adjust the parameters of the
current loop regulator
