Notes on Motor Protection
• Motor protection meeting UL and cUL standards is achieved with the motor overload
protection time (L1-02) set to factory default setting. Normally, L1-02 (Motor Overload
Protection Time) does not require setting. If the motor overload tolerance is clear, set the
overload protection time at hot start according to the motor. To detect overload earlier,
decrease the setting.
Figure 4.19 illustrates motor protection operation time characteristics.

4.5 Basic Operation
Cooling Ability
Motor designed to operate
from line power.
Motor cooling is most
effective when running at
rated nameplate base
frequency (check the motor
specifications).
Motor is designed to
effectively cool itself at
speeds as low as 6 Hz.

Overload
Characteristics
Operating continuously
at less than line power
frequency can trigger
motor overload
protection (oL1). A fault
is then output and the
motor will coast to stop.
Continuous operation
with 100% load from 6
Hz to 50/60 Hz.
