Servo Drive
 Servo Alarm
If the drive detects a problem, it will trigger a servo alarm and transition to the servo off state to stop. In this
case, the value of the emergency stop setting (0x2013) is used to stop the drive.
Alarm Code Causes Details What to check
IPM fault
Over current
Current limit exceeded
Motor cable
error
Wiring is incorrect and check short Replace motor cable
Encoder cable
error
Wiring is incorrect and check short Replace encoder cable
Parameter cable

Motor ID [0x2000], encoder
type[0x2001], encoder form[0x2002]
setting vaule should be same with
applied to motor label.
Modifty motor label and parameter
concordantly
Check motor
phase resistor
Check if U/V/W phase
currentffset(0x2015~0x2017) is 5% or
above of the rated current, Replace
drive
Replace motor
Machine part
has problem
Determine whether there is a conflict
or binding in the equipment.
Check machine part
Drive error
If alarm continue after servo on again,
Replace drive. Because drive may
have problem.
Error by noize
Check method to improve noise of
wiring, install.
Please check condition of wiring for
FG. Match wire size of FG with wire
size of drive main circuit.

Drive error
If alarm continue after servo on again,
Replace drive. Because drive may
have problem.
Current offset
Motor U/V/W
phase current
offset
oversetting
Check whether the U/V/W phase
current offset [0x2015~0x2017] are 5%
of the rated current or highter.
Rerun adjusting phase current offset
Drive error
If alarm occurs continually after
adjusting offset of phase current,
please replace new drive because
drive has problem.
Continuous overload
In case of
sequent
operating that
exceed rated
Check if load which is accumulating
driving load rate[0x2603]
is below 100% when it is in constant Change drive and motor capacitiy,
Please tune gain.
