· General-purpose and Blower-cooled Motors
Induction motors are classified as general-purpose or blower-cooled
motors, based on their cooling capabilities. Hence, the motor overload
detection function operates differently for each of these two motor types.
Cooling Effectiveness
Effective when operated at
50/60Hz from commercial
power supply.
Effective when operated at
low speeds (approx. 6Hz).

During continuous operation at low
speeds, the load must be limited in
order to limit motor temperature rise.

Electronic Thermal
Overload
"OL1" error (motor overload
protection is enabled when
motor is continuously oper-
ated at 50/60Hz or less at
100% load).
Effective when operated at
low speeds (approx. 6Hz).
