Fault Codes
‑709‑
Fault Name Display Possible Cause Action
Overvoltage during
acceleration
E05.00 High input grid voltage Adjust the voltage to the normal range.
External force driving the motor
during acceleration
Cancel the external force or install a braking
resistor.
If the value of F3‑26 (frequency rise threshold
during overvoltage suppression) is too small,
adjust it to a level between 5 Hz to 15 Hz when an
external force drives the motor.
Inappropriate overvoltage
suppression
Ensure that overvoltage suppression (F3‑23) is
enabled.
If the value of F3‑22 (overvoltage suppression) is
too large, adjust it to a level between 700 V and
770 V.
If the value of F3‑24 (frequency gain for
overvoltage suppression) is too small, adjust it to
a level between 30 and 50.
The braking unit and braking
resistor are not installed.
Install a braking unit and a braking resistor.
Excessively short acceleration
time
Increase the acceleration time.
Overvoltage during
deceleration
E06.00 Inappropriate overvoltage
suppression
Ensure that overvoltage suppression (F3‑23) is
enabled.
If the value of F3‑22 (overvoltage suppression) is
too large, adjust it to a level between 700 V and
770 V.
If the value of F3‑24 (frequency gain for
overvoltage suppression) is too small, adjust it to
a level between 30 and 50.
External force driving the motor
during deceleration
Cancel the external force or install a braking
resistor.
If the value of F3‑26 (frequency rise threshold
during overvoltage suppression) is too small,
adjust it to a level between 5 Hz to 15 Hz when an
external force drives the motor.
Excessively short deceleration
time
