Possible Cause Solution
Fault Type
Overvoltage during
acceleration
E05.00
The input grid voltage is too
high.
Adjust the input grid voltage to the normal range.
Axis fault
An external force drives the
motor during acceleration.
Cancel the external force or install a braking resistor.
The maximum rise frequency during overvoltage stall
suppression (F3-26) is too low. Adjust it to a value
between 5 Hz and 15 Hz when an external force is
applied.
The overvoltage stall
suppression parameters are
set improperly.
Ensure that the overvoltage stall suppression
function (F3-23) is enabled.
The overvoltage stall suppression voltage (F3-22) is
too high. Adjust it to a value between 700 V and 770
V.
The overvoltage stall suppression frequency gain (F3-
24) is too low. Adjust it to a value between 30 and 50.
The power supply unit is not
provided with a braking unit
and no braking resistor is
installed.
Replace the power supply unit with one that has a
braking unit and install a braking resistor.
The acceleration time is too
short.
Increase the acceleration time (F0-17).
Overvoltage during
deceleration
E06.00
The overvoltage stall
suppression parameters are
set improperly.
Ensure that the overvoltage stall suppression
function (F3-23) is enabled.
The overvoltage stall suppression voltage (F3-22) is
too high. Adjust it to a value between 700 V and 770
V.
The overvoltage stall suppression frequency gain (F3-
24) is too low. Adjust it to a value between 30 and 50.
Axis fault
An external force drives the
motor during deceleration.
Cancel the external force or install a braking resistor.
The maximum rise frequency during overvoltage stall
suppression (F3-26) is too low. Adjust it to a value
between 5 Hz and 15 Hz when an external force is
applied.
The deceleration time is too
short.
Increase the deceleration time (F0-18).
The power supply unit is not
provided with a braking unit
and no braking resistor is
installed.
Replace the power supply unit with one that has a
braking unit and install a braking resistor.
