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.

Motor is designed to effectively cool

Setting 4: PM derated torque motor
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Use this setting when operating a PM motor. PM motors for derated torque have a self-cooling design and 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.

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 5: Constant torque PM motors (constant torque range of 1:500)
Note:
PM motor control modes are not available on 600 V class drives, CIMR-Ao5oooooooo.
Sets necessary protection characteristics when driving a PM with constant torque. These motors allow for a speed control from
0.2% to 100% when operating with 100% load. Slower speeds with 100% load will trigger overload.
