1.1.2. During Power Up
Danger
z Do 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.
z When 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.
z When 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.
z When 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 is OFF, the inverter will not run
after restart.
3. When 00-03(or00-04) =1, the external switch 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
personnel on sudden resumption of power.
z If 4-09 is set to 0 (direct start up), please refer to the description and warnings for 04-09
to verify the safety of operator and machine.
1.1.3. Before Operation
Danger
Make sure the model and inverter capacity are the same as that set in parameter 12-00.
Caution
On power up the supply voltage set in parameter 05-03 will flash on display for 2 seconds.
