Setting 2: Drive dedicated motor (speed range for constant torque: 1:10)
Use this setting when operating a drive duty motor that allows constant torque in a speed range of 1:10. The drive will allow
the motor to run with 100% load from 10% up to 100% speed. Running at slower speeds with full load can trigger an overload
fault.

Setting 3: Vector motor (speed range for constant torque: 1:100)
Use this setting when operating a drive-dedicated motor that allows constant torque in a speed range 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.

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 is designed to effectively cool
itself even at low speeds.
C
Motor is designed to effectively cool
itself at speeds near 0.6 Hz.
C
Motor designed to operate from line
power. Motor cooling is most effective
when running at rated base frequency
(check the motor nameplate or

Overload Characteristics
Continuous operation with 100% load
from 0.6 Hz to E1-06, Motor Base
Frequency.
Continuous operation below 0.6 Hz
may cause an oL1 or oL2 fault.
Overload Characteristics
Continuous operation at less than line
power frequency with 100% load can
trigger a motor overload fault (oL1). A
fault is output and the motor will coast
to stop.
