When power is applied
WARNING
Do not attempt to install or remove input or out put connectors of T-verter when the
power supply is turned on. Otherwise, the T-verter may be damaged due to the surge
peak caused by the insertion or removal.
Under Operation
WARNING
z
Do not use a separate device to switch ON or OFF motor during operation.
Otherwise, the T-verter may experience an over-current breakdown.
z
When momentary power loss is longer than 2 seconds (the large of horse power,
the longer of time), the inverter does not have enough storage power to control the
circuit; Therefore, when power is regenerated, the operation of the inverter is
based on the setup of Fn_10/16 and the condition of external switch, this is
considered to be
「
restart
」
in the following paragraphs.
z
When the momentary power loss is short, the inverter still has enough storage
power to control the circuit; therefore, when power is regenerated, the inverter will
automatically start operation again depends on the setup of Fn_31/32.
z
When restart the inverter, the operation of the inverter is based on the setup of
Fn_10 and the condition of external switch (FWD/REV button). Attention: the
restart operation is irrelevant with Fn_31/32/34/35.
(1) When Fn_10=0, the inverter will not start after restart.
(2) When Fn_10=1 and the external switch (FWD/REV button) is OFF, the
inverter will not start after restart.
(3) When Fn_10=1, the external switch (FWD/REV button) is ON, and
Fn16=XXX0, the inverter will start automatically after restart. Attention: Base
on safety reason, please turn off the external switch (FWD/REV button) after
power loss to avoid possible damage to the machine and the human body
after sudden regeneration of power.
WARNING
z
Do not remove the front cover of the T-verter when the power is ON to avoid
personnel injury caused by electrical shock.
z
When the automatic restart function is enabled, the motor and machinery will be
restarted automatically.
