1 : General-Purpose Motor (Standard Motor)
The motor is self-cooled so the overload tolerance falls when the motor speed is decreased.
The Electrothermal relay trigger level changes according to the motor overload characteristics
to protect the motor from overheat throughout the entire speed range.

from line power.
Motor cooling is most
effective when
running at 50/60 Hz
Running continuously at
below 50/60 Hz triggers an
oL1 fault. A fault is output and
the motor will coast to stop.
2 : Drive Dedicated Motor (Constant Torque Range 1 : 10)
The motor is allowed to run with 100% load from 10% to 100% speed. When the motor runs
slower with 100% load, an overload fault will be triggered.
