WARNING
❙ Do not attempt to install or remove input or output connectors of the AC drive when the power supply is turned on.
Otherwise, it may be damaged due to the surge peak caused by the insertion or removal of power.
❙ When momentary power loss is longer than 2 seconds (the larger the horsepower, the the longer the time), the AC drive
does not have enough storage power to control the circuit; therefore,when power is restored,the operation of the
AC drive is based on the setup of F_10 and the condition of external switch.This is considered to be a restart as pertaining
to the following paragraphs.
❙ When the momentary power loss is short, the AC drive still has enough storage power to control the circuit; therefore,
when power is restored, the drive will automatically start operation again depending on the setup of F_23.
When restarting the drive, the operation is based on the setup of F_10 and the condition of external switch (FWD/REV
button). Attention: the restart operation is determined by F_23 and F_24.
(1) When F_10=0, the AC drive will not start in restart mode.
(2) When F_10=1 and the external switch (FWD/REV button) is OFF, the inverter will not start in restart mode.
(3) When F_10=1 and the external switch (FWD/REV button) is ON, the inverter will start automatically in restart mode.
Attention: Based on safety, please turn off the external switch (FWD/REV button) after power loss to avoid possible
damage to the machine and personnel after sudden restoration of power.
Under Operation
WARNING
Do not use a separate device to switch motor ON or OFF during operation. Otherwise, the AC drive may experience an
overcurrent breakdown.
WARNING
❙ To avoid personal injury caused by electrical shock, do not remove the front cover of the AC drive while the power is ON.
❙ When the automatic restart function is enabled, the motor and machinery will be restarted automatically.
