Code Details
・By the load and the operating
E001
conditions, overcurrent has
occurred
・By the load and the operating
E005
conditions, current has
E039
increased.
・Braking resistor use is limited.
E006
・Internal voltage has increased
・Insufficient capacity of the
E007
inverter
E008
・Main CPU abnormality
E011
・Main circuit supply has drop
E009
・Current detector abnormality
E010
・[EXT] input terminal is ON
E012
・[USP] input terminal is ON if at
E013
the start-up, the RUN command
was issued right at the start up

Corrective actions
・ If the acceleration is fast, increase the acceleration time
・Use the overcurrent suppression function
・Use the overload restriction function
・Use the overcurrent retry function
・In order to stabilize the control, adjust the constant
・ If the acceleration is fast, increase the acceleration time
・Use the overload restriction function
・If the motor sound is abnormal, in order to stabilize the
control, adjust the constant
・If the deceleration is fast, increase the deceleration time
・Reselection of the braking resistor is necessary
・If the deceleration is fast, increase the deceleration time
・Use the overvoltage suppression functions
・Use the overvoltage retry function
・Use a braking option
・Carry out counter measures for the inverter noise
・Consecutive errors may cause a failure
・To disable the undervoltage error, change setting
・Use the undervoltage retry function
・Carry out counter measures for the inverter noise
・Consecutive errors may cause a failure, replacement of
the components is necessary
・Check the signal status of the input terminal
・Check if there are no operations by communication or
programme
・Make sure that an operation command is not introduced
at the time of turning ON the inverter
