Inspection of the Controller
Corrective measures
Cause Corrective measures
1
Position command frequency is too high,
or acceleration/deceleration time is too
short.
Review controller position
command.
2
Load inertia is too large or motor capacity
is too small.
Review load conditions, or
change to larger capacity motor.
3 Holding brake is not released
Check and correct wiring.
Replace servomotor if wiring is
correct (and voltage is
specified),
4
Motor is mechanically locked, or there is
mechanical interference
Review mechanics
5
Among one or all of the U, V, W phases
between amplifier and motor is
disconnected.
Check wrong wiring and correct
it.
6
At the stop timing (or complete
positioning), Motor was forced to rotate
caused by gravity or likely external force.
Review the load or replace with
larger capacity motor.
7
Current limit setting value is insufficient
in spite that this function command input
is active.
Set encoder pulse number does not
match motors.
A sufficient current limit value
should be set or let this
function void.
Correct the encoder pulse
number of the motor.
8
Improper servo parameter setting (position
loop gain, etc.)
Correct these parameters. (ex.
enlarging the position loop gain).
9 Excess deviation setting is too small. Set sufficient deviation value.
10 Faulty amplifier control board Replace servo amplifier.
11 Faulty servomotor encoder Replace servomotor.
12 Power supply voltage drop Review power supply voltage
Alarm Code D2H (Error of position command pulse frequency 1)
Operating state when alarm occurred
Possible causes
Operating state
1
After position command pulse input High
Corrective measures
Cause Corrective measures
1
Many command pulses are input beyond
digital filter setting value (frequency).
Decrease the frequency of
command pulses input.
Increase digital filter setting
frequency.

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
CPU is unable to read correct value from
non-volatile memory built in the amplifier.
Replace servo amplifier
2 Faulty amplifier control board Replace servo amplifier

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
