Description of Warning Codes

Cause
Troubleshooting
Solution
When an external
regenerative resistor is used
(H02.25 = 1 or 2), the
resistance of this resistor is
lower than the minimum
resistance allowed by the
servo drive.
Measure whether the
resistance of the external
regenerative resistor
between terminals P⊕ and
C is lower than the value of
H02.21 (Permissible
minimum resistance of
regenerative resistor).
● If yes, replace with an
external regenerative
resistor that matches the
servo drive, then set
H02.27 according to the
resistance of the resistor
used. Finally, connect the
new resistor between P⊕
and C.
● If not, set H02.27 to a value
consistent with the
resistance of the external
regenerative resistor used.
● E924.0: Regenerative transistor overtemperature
Description:
The estimated temperature of the regenerative transistor is higher than H0A.18
(IGBT overtemperature threshold).
Cause
Troubleshooting
Solution
1. The junction temperature
of the regenerative
transistor is too high.
2. The regenerative
transistor will be turned off
automatically after overload
occurs.
The regenerative transistor
temperature exceeds the
threshold defined by H0A.49.
Control the working
conditions and usage of the
regenerative transistor.
● E941.0: Parameter modifications activated at next power‑on
Description:
The parameters modified are those whose "Effective time" is "Next power‑on".
Cause
Troubleshooting
Solution
The parameters modified
are those whose "Effective
time" is "Next power‑on".
Check whether parameters
you modified are those
whose "Effective Time" is
"Next power‑on".
Power off and on the servo
drive again.
● E942.0: Parameter saved frequently
Description:
The number of parameters modified at a time exceeds 200.
Cause
Troubleshooting
Solution
Too many parameters are
modified and saved to
EEPROM (H0C.13 = 1) at a
brief interval.
Check whether parameters
are modified through the
host controller at a brief
interval.
Check the operation mode.
For parameters that need
not be saved to EEPROM, set
H0C.13 to 0.
