1.1.2. DuringPowerUp
Danger
zDo not insert or remove input connections to the inverter when powered up to avoid
damage to the control board resulting from possible voltage surge due to contact
bounce.
zWhen the momentary power loss is short, the inverter still has enough storage power
to control the circuit. Therefore, when power is re-applied, the inverter will
automatically restart depending on the setup of 04-03/04-04.
zWhen momentary power loss is longer than 2 seconds (the larger of horse power, the
longer of time), the inverter does not have enough storage power to control the circuit;
Therefore, when the power is re-applied, the operation of the inverter is based on the
setup of 00-03(or00-04) /04-09 and the condition of external switch, this is considered
to be「restart」in the following paragraphs.
zWhen restarting the inverter, the operation of the inverter is based on the setup of
00-03(or00-04) and 04-09 and the condition of external switch (FWD/REV button).
Attention: the start operation will be regardless of 04-03/04-04/04-06/04-07.
1. When 00-03(or00-04) =0, the inverter will not automatically run after restart.
2. When 00-03(or00-04) =1 and the external switch (FWD/REV button) is OFF,
the inverter will not run after restart.
3. When 00-03(or00-04) =1, the external switch (FWD/REV button) is ON, and
04-09=0, the inverter will run automatically after restart.
Attention: To ensure safety, please turn off the external switch (FWD/REV button)
after power loss, to protect machines from possible damage and potential injury to
