1.1.4 During Operation
Danger
Chapte 1 Safety Precautions
Do not engage or disengage the motor during operation. Otherwise, the over-current will
cause the inverter to disconnect or the main circuit to burn.
Danger
To avoid electric shock, do not take the front cover off during electrifying
The motor will restart automatically after stop when auto-restart function is on. In this
case, do not get close to the machine.
Note: The stop switch is different from the usage of the emergency stop switch. It must
be set first to be effective.
Caution
Do not touch heat-generating components such as heat sink and braking resistor.
The inverter can drive the motor running from low speed to high speed. Verify the
allowable capacities range of the motor and the mechanism.
Note the settings related to the braking reactor.
Do not check signals on circuit boards while the inverter is running.
Caution
It is after 5 minutes that disassembling or checking the components could be performed as
power supply OFF and the indicator turned off.
1.1.5 During Maintenance
Caution
The inverter should be used in a non-condensed environment with temperature from –10
to +40 and relative humidity of 95% non-condense.
Caution
When the inverter top cover has removed, it can be used in a non-condensed environment
with temperature from –10 to +50 and relative humidity of 95%, but the environment
should be free from water and metal dust.
