L1-02: Motor Overload Protection Time
Sets the time it takes the drive to detect motor overheat due to overload. This setting rarely requires adjustment, but
should correlate with the motor overload tolerance protection time for performing a hot start.
Defaulted to operate with an allowance of 150% overload operation for one minute.
shows an example of the electrothermal protection operation time.

n
L1-06: Motor Overload Detection Start Level
Sets the start level for motor overload detection as a percentage of the motor rated current. Set L1-06 to a smaller value
than the setting for L1-07.
n
L1-07: Motor Overload Detection Level
Sets the current
level for motor overload detection as a percentage of the motor’s rated current. Set L1-07 to a larger
value than the setting for L1-06.
n
L1-13: Continuous Electrothermal Operation Selection
Determines whether to hold the current value of the electrothermal motor protection (L1-01) when the power supply is
interrupted.
