 Servo Warning
If the drive detects an error classified as a servo warning, it will trigger a warning. In this case, the drive will
maintain normal operation condition. After the cause of the warning is eliminated, the warning will be
automatically cleared. In case of a warning, take an appropriate action. You can specify if each warning is
checked with warning mask configuration (0x2014).

4 W10 Operation overload
5 W20
Abnormal combination of Drive and Motor,
abnormal I/O setting
6 W40 Low voltage
7 W80 Emergency signal input
Alarm Code Causes Detail What to check
PWR_FAIL
Main power
input voltage
error
Check voltage between phase 380-
480[Vac] of L1, L2, L3
Recheck power supply.
Parameter
setting error
Check value of main power input
mode set[0x2006] arroding to state of
main power input.
Wire or set parameter as input power
on(possible 3 phase)
Momentary
power failure
Check value of main power input
mode set[0x2006] arroding to state of
main power input. Check actual main power or increase
value of checking time of loss of main
power.
Drive error
If alarm continue after servo on again,
Replace drive. Because drive may have
problem.
LOW_BATT
Parameter
setting error
Check setting value of absolute
encoder [0x2005]
Alarm will be disappeared if you set “1”
when using ABS encoder as incremental
encoder.
Bad conection of
battery, No
connected.
Check the status of battery Connect battery rightly.
When battery
voltage is low.
Check whether battery voltage is over
3.3V
Replace battery.
SW_POS_LMT
Parameter
setting error
Setting function of software restriction
on location [0x2400], Check value of
software restriction on
location[0x607D] Change value of software position limit
function[0x2400] or change the set of limit
value of maximum postion and minimum
position of software position limit[0x607D]
OV_LOAD
In case of
sequent
Check overload warning level
setting[0x2010] and constant speed
section or accumulated operation
Change drive and motor capacitiy,
Please tune gain.
