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 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.
Overload Tolerance Cooling Ability Overload Characteristics
Motor is designed to effectively cool itself even at
low speeds.
Continuous operation with 100% load from 5 Hz to
50 Hz.
Overload Tolerance Cooling Ability Overload Characteristics
Motor is designed to effectively cool itself at ultra-
low speeds.
Continuous operation with 100% load from 0.5 Hz to
50 Hz.
Overload Tolerance Cooling Ability Overload Characteristics
Motor is designed to produce 100% torque at base
speed. Built with effective cooling capabilities.
Reaching 100% when operating at below the base
frequency will cause a motor overload fault (oL1).
The drive fault output closes and the motor coasts to
stop.
