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 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 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 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.
zIf 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. BeforeOperation
Danger

Caution
On power up the supply voltage set in parameter 05-03 will flash on display for 2 seconds.

1-3
1.1.4. DuringOperation
Danger
Do not connect or disconnect the motor during operation. Otherwise, the over-current will
cause the inverter to trip or damage the unit.
Danger
zTo avoid electric shock, do not take the front cover off when power is on.
zThe motor will restart automatically after stop when auto-restart function is on. In this
case, use caution while working near the drive, motor, or driven equipment.
zNote: The stop push button and external stop command have no safety function.
For Emergency stop, it is necessary to use a correct latch type push button and an
appropriate circuit or devices to ensure safety.
Caution
zDo not touch heat-generating components such as heat sinks and braking resistors.
zThe inverter can drive the motor from low speed to high speed. Verify the allowable
speed range of the motor and the load before operation.
