High-efficiency operation with light load
Apply the torque limit function.
Turn the monitor to the output power indication.
Use the fault retry function.
Select the momentary power loss
reset and restart mode.
Select the automatic continuous operation
mode when frequency reference is missing.
Use the preset frequency band
prohibition function (frequency jump
control). Up to 3 frequencies prohibited.
Use the frequency reference lower limit.
Inverter start from coasting stop
status without stopping the motor.
Continue operation even when momentary
power loss not longer than 2 seconds occur.
Continue operation even if a failure occures in
higher-order frequency reference equipment.

Avoid mechanical resonance.
Wants to prevent machine stop
page caused by inverter tripping.
Save energy since the load is not
heavy at low-speed operation.
Avoid overload tripping.
Monitor output power.
The resonance point will be passed,
and continuous operation is
eliminated at this point.

Use the speed search operation with
speed calculation.
