Alarm Code D3H (Error of position command pulse frequency 2)
Operating state when alarm occurred
Possible causes
Operating state
1 2
After position command pulse input High High
Corrective measures
Cause Corrective measures
1
The frequency of command pulses
input.
Decrease the frequency of command
pulses input.
2
Electric gear setting value is too
high.
Decrease electric gear setting value.
Alarm Code DFH (Test mode close)
Operating state when alarm occurred
Possible causes
Operating state
1
After test mode close High
Corrective measures
Cause Corrective measures
1 Normal operation.
Clear alarm to recover (This is in considering to
deviation left at controller after test mode
Alarm Code E1H (EEPROM error)
Operating state when alarm occurred
Possible causes
Operating state
1 2
When control power supply is turned on High Low
During the operation for remote operator keys or PC interface High
Corrective measures
Cause Corrective measures
1

Alarm Code E2H (EEPROM internal data error)
Operating state when alarm occurred
Possible causes
Operating state
1 2
When control power supply is turned on Low High
Corrective measures
Cause Corrective measures
1
CPU is unable to read correct value
from non-volatile memory built-in
the amplifier.
Replace servo amplifier
2
Unable to write to non-volatile
memory at last turning OFF.
After changing some parameters,
confirm no alarm occurrence when
power supply is connected to source
again. →In case that an alarm
continues, replace servo amplifier.
Alarm Code E3H (Internal RAM error)
Alarm Code E4H (Process error between CPU and ASIC)
Operating state when alarm occurred
Possible causes
Operating state
1
When control power supply is turned on High
Corrective measures
Cause Corrective measures
1 Faulty amplifier control board. Replace servo amplifier
Alarm Code E5H (Parameter error 1)
Operating state when alarm occurred
Possible causes
Operating state

Corrective measures
Cause
Corrective measures
1
The value of system parameter is
outside the setting range.
Check servo amplifier model.
Check the setting value of system
parameter and correct it.
→Turn on the power supply again and
check no alarm.
2 Faulty servo amplifier Replace servo amplifier
Alarm Code E6H (Parameter error 2)
Operating state when alarm occurred
Possible causes
Operating state
1 2
When control power supply is turned on High High
After changing any system parameters High
Corrective measures
Cause Corrective measures
1
The setting value of system
parameter does not match that of
actual hard ware.
Wrong combination of system
parameter setting
Check servo amplifier model.
Check the setting value of system
parameter and correct it. →Turn on
the power supply again and check no
alarm.
2 Faulty servo amplifier Replace servo amplifier
Alarm Code F1H (Task process error)
Operating state when alarm occurred
Possible causes
Operating state
1
During operation High
Corrective measures
Cause Corrective measures
1 Faulty amplifier control circuit Replace servo amplifier.
Alarm Code F2H (Initial timeout)
