Possible Cause Solution Fault Type
Overvoltage during
acceleration
E05.00 The input grid voltage is
too high.
Adjust the input grid voltage to 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 prevention (F3‑26) is too
small. Its recommended range is 5 Hz to 15
Hz. Adjust this parameter when an external
force is applied.
The overvoltage stall
prevention parameters
are set improperly.
Ensure that the overvoltage stall prevention
function is enabled (F3‑23 = 1).
The overvoltage stall prevention voltage (F3‑
22) is too high. Adjust it between 700 V and
770 V.
The overvoltage stall prevention frequency
gain (F3‑24) is too low. Adjust it between 30
and 50.
The power supply unit
with a braking unit and
the braking resistor are
not installed.
Replace the power supply unit with one with
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
prevention parameters
are set improperly.
Ensure that the overvoltage stall prevention
function is enabled (F3‑23 = 1).
The overvoltage stall prevention voltage (F3‑
22) is too high. Adjust it between 700 V and
770 V.
The overvoltage stall prevention frequency
gain (F3‑24) is too low. Adjust it between 30
and 50.
