■Action when an error occurs
*1) As a major failure error, the output terminal function [MJA] turns
ON. And these errors could not be canceled with input terminal
028[RS].

E001
By the load or the operating
conditions, overcurrent has
occurred.
・If the acceleration is fast, increase the acceleration time.
[AC120]
・Use the overcurrent suppression function.
[bA120]
・Use the overload restriction function.
[bA122]
・Use the overcurrent retry function.
[bb-22]
・In order to stabilize the control, Try auto-tuning for motor constants.
[HA-01]
E005
E039
By the load and the operating
conditions, current has
increased.
・ If the acceleration is fast, increase the acceleration time.
[AC120]
・Use the overload restriction function.
[bA122]
・If the motor sound is abnormal, in order to stabilize the control, adjust the
motor constant by trying auto-tuning.
[HA-01]
E006
Braking resistor use is
limited.
・If the deceleration is fast, increase the deceleration time.
[AC122]
・Reselection of the braking resistor is necessary.
[bA-60]
E007
The inverter's P-N voltage has
increased due to the
regenerative voltage during
sudden deceleration and
lowering of the motor.
・If the deceleration is fast, increase the deceleration time.
[AC122]
・Use the overvoltage suppression functions.
[bA140][bA146]
・Use the overvoltage retry function.
[bb-23]
・Use the regenerative braking option.

E008
E011 *1)
Main CPU abnormality.
・Carry out counter measures for the inverter noise.
-
・If it occurs consecutively, there is a possibility of inverter failure.
-
E009
Main circuit supply has drop.
・To disable the under-voltage error, change setting.
[bb-27]
・Use the under-voltage retry function.
[bb-21]
E010
*1)
Current detector
abnormality.
・Carry out counter measures for the inverter noise.
-
・ If it occurs consecutively, there is a possibility of inverter failure, and parts
replacement might be required.
-
E012
Input terminal 033[EXT] is ON.
・Check the signal status of the input terminal.
[dA-51]
・Check if there are no operations by communication or EzSQ program.
-
E013
While the input terminal
034[USP] was ON and the RUN
command is input state, the
main power supply was turned
ON.
・Make sure that an RUN command is not introduced at the time of turning
ON the inverter.
[dA-51]
E014
*1)
Ground fault is detected at
main power supply turned ON.
・Check insulation deterioration and ground fault of the motor, the
wiring and etc..
-
E015
The main power supply
voltage has been continuously
above the limit.
・Review the power circumstances, such as the power supply
capacity.
[dA-40]
E016
The control circuit power
supply was off due to
instantaneous power supply
failure.
・If avoiding this trip is required, use the power loss retry function.
