Alarm Code Causes Details What to check
Drive error
If alarm continue after servo on
again, Replace drive. Because
drive may have problem.
Under voltage
Main power
input voltage
error
Check the main power voltage
is over 3phase 134[Vac]
Recheck the power supply.
Check DC link value [0x2605]
is over 190[Vdc] when main
power is accordingly input
Replace the drive.
running when
power
voltage is low
Check wiring of main power
supply Use 3 phase as supply
voltage.
Over voltage
Main power
input voltage
error
Check whether the main power
voltage is below 253[Vac]
Recheck the power supply.
Check DC link value [0x2605]
is below 405[V] when main
power is accordingly input
Replace the drive.
When
braking
resistor is
high
Check operating condition
regenerative resistance.
Review the regenerative
resistance consider the
operating condition and load.
Setting value
of
acceleration/
deceleration
In case of many time for
acceleration/ deceleration Set longer acceleration/
deceleration time
Drive error
If alarm continue after servo on
again, Replace drive. Because
drive may have problem.
Main power fail
Main power
input voltage
error
check voltage between phase
200-230[Vac] of L1, L2, L3
Recheck power supply.
Parameter
setting error
Check setting value to state of
main power [0x2006] Wire or set parameter as input
power on (possible 3 phase)
momentary
power failure
Check setting value [0x2007]
Check main power source or
reduce value of [0x2007]
Drive error
If alarm continue after servo on
again, Replace drive. Because
drive may have problem.
Control power fail
Voltage
between
phase of C1,
C2 error
Voltage between phase of
C1, C2 is within 200-230[Vac].
Recheck power supply of drive
Drive error
If alarm continue after servo on
again, Replace drive. Because
drive may have problem.
Over speed limit
Motor
Encoder
error
Wiring is incorrect and check
Short.
Replace motor cable.
Encoder
cable error
Wiring is incorrect and check
Short.
Replace encoder cable.
Parameter
setting error
Value of [0x2000], [0x2001],
[0x2002] is same with Modify the parameter as same
as motor label information.
