Motor is designed to effectively cool
itself at speeds as low as 6 Hz.
Continuous operation with 100% load
from 6 Hz to 50/60 Hz.
Setting 3: Vector Motor (constant torque, 1:100)
Use this setting when operating a drive dedicated motor with a torque ratio of 1:100. This motor type is allowed to run with
100% load from 1% up to 100% speed. Running slower speeds with full load can trigger an overload fault.

Motor is designed to effectively cool
itself at speeds as low as approximately
0.6 Hz.
Continuous operation with 100% load
from 0.6 Hz to 50/60 Hz.
Setting 6: General-Purpose Motor
Note: General-purpose motors are designed with a base speed that operates at line frequency (50/60 Hz depending on geographic region).
Because the motor is self-cooled, the overload tolerance drops when the motor speed is lowered. The drive appropriately
adjusts the electrothermal trigger point according to the motor overload characteristics and protects the motor from overheat
throughout the entire speed range.

Motor designed to operate from line
power. Motor cooling is most effective
when running at rated base frequency
(check the motor nameplate or
specifications)
Continuous operation at less than line
power frequency with 100% load can
trigger motor overload protection
(oL1). A fault is output and the motor
will coast to stop.
n
L1-02: Motor Overload Protection Time
Sets the time for the drive to shut down on motor overload (oL1) when the motor is running with excessive current. Enter the
time the motor can withstand operating at 150% current after previously running at 100% current (hot motor overload
condition). This parameter rarely requires adjustment.
