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

approximately 0.6 Hz.
Continuous operation with 100%
load from 0.6 Hz to 50/60 Hz.
Setting 4: PM Derated Torque Motor
This setting is for operating a PM motor.
PM motors for derated torque have a self-cooling design, so the overload tolerance
drops as the motor slows. Electronic thermal overload is triggered in accordance with the motor overload characteristics,
providing overheat protection across the entire speed range.

Torque (%)
Motor is designed to produce 100%
torque at base speed. Built with
effective cooling capabilities.
Reaching 100% when operating at
below the base frequency causes a
motor overload fault (oL1). The
drive fault output closes and the
motor coasts to stop.
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.
