12. Maintenance and Checkup
Alarm Code
Name
Causes
Drive error
In case of sequent operating
that exceed rated load
Checklist
Troble shooting
Check if load which is accumulating
driving load rate[0x2603]
is below 100% when it is in constant
speed section and stop
If alarm occurs continually after
adjusting offset of phase current,
please replace new drive
because drive has problem.
Change drive and motor
capacitiy.
Please tune gains
Motor brake error
Check set value, encoder wiring
Provide power to motor brake
Continuous overload
Parameter setting error
Machine has problem
Check encoder wiring, replace
encoder
Check encoder wiring, replace
encoder
there is no problem for running
Modify the parameter as same
as motor label information.
Set as proper value
Check machine part.
Motor cable error
Encoder cable error
surrounding temerature
Drive temperature 1
Drive error
Capacity excess by high
frequency operationg or
Continue regenerative
operating
Regeneration overload
Parameter setting error
Emergency stop
Drive error
Motor cable open
Motor cable error
Motor error
Drive error
Wiring is incorrect and check short Replace motor cable.
Wiring is incorrect and check short
Check wherther surrounding
temperature is over 50 [℃]
Check if displayed value 1 [0x260B]
of drive temperature is much
different with surrounding
temperature when it is normal
condition.
Check encoder abnormality, encoder
set value, encoder wiring, gain
setting, motor wiring, motor ID,
electronic gear ratio,
speedcommand scale
Check positionerrorrange (0x6065)
andpositionerrorexcess time
(0x6066) Set Value, wiring and limit
contact, gainset value, ecoder
setting, electronic gear ratop setting.
Check for equipment arrest and load
status.
Check emergency stop input.
Check excessive speed error alarm
detection level (0x2310), wiring and
limit contact, gainset value, encoder
setting, electronic gear ratio setting.
Check for equipment arrest and load
status.
Check whether cable is
disconnected.
Check short circuit of U,V,W in
Motor (U-V, V-W, W-U)
Replace encoer cable.
Lower surrounding temperature
of drive
Replace the drive
Adjust value on 0x2009. Use
braking resistor
Set as proper value
Recheck the power supply
Replace the drive
Replace motor cable
Replace motor
If specific alarm signal is
persistently occurred, It is highly
possible to have fault, so Kindly
recommend you to change the
servo drive.
