Description of Warning Codes
‑16‑
Cause
Confirming Method
Solution
An error occurs during
parameter‑reading.
Modify a certain parameter,
power off and on the servo
drive again and check
whether the modification is
saved.
If the modification is not
saved and the fault persists
after the servo drive is
powered off and on
repeatedly, replace the
servo drive.
● E108.4: Single data stored too many times
Cause:
Single data is stored too frequently.
Cause
Confirming Method
Solution
That may damage e2prom
over time.
1. Check H0b.90 and H0b.91.
H0b.90 shows the
parameter in question or
object dictionaries (in
hexadecimal). If H0b.91=
15, H0b.90 shows internal
variables of software.
2. Check "Func Test 1"
through the oscilloscope
channel. Be sure to
display it in hexadecimal.
This channel displays the
address that e2prom is
storing.
3. Check the storage count
through the oscilloscope
channel "Func Test 2".
1. If the alarm is caused by
manually modifying a
certain parameter or
object dictionary, there
will be no frequent
storage of a certain data
during operation, and you
can reset the fault.
2. Check the abnormal
parameter through H0b.
90 or oscilloscope
channel, and find out the
cause. For example, if the
host controller program
frequently writes
parameters through SDO,
you can modify the
program to stop it.
● E110.0: Frequency‑division pulse output setting error
Cause:
Frequency‑division pulse output setting error
Cause
Confirming Method
Solution
The number of frequency
divisions (quadrupled)
exceeds the motor
revolutions
Check the setpoint of
H05.17.
Adjust the value of H05.17
on the basis of the motor
revolutions.
● E120.3: The motor and drive do not match in the power
Cause:
the motor and drive do not match in the rated power.
