About the 1SU44001

1SU44001 is an SP500 drive that is manufactured by Reliance Electric. This drive has a rated horsepower of 0.25-1.0 HP and is contained in a NEMA 4/12 enclosure. The rated voltage is 380-460 VAC. The enclosure size for this drive is size B. The dimensions of Enclosure B are 301.7 mm (11.88 in) (H) x 160.1 mm (6.3 in) (D) x 222.3 mm (8.75 in) (W). The weight of enclosure B is 5.4 kg (12 lb).

Minimum speed is the F-03 parameter on the SP500 drive. This parameter has a range of 3-30 Hz and a step size of 0.1 Hz (if the maximum speed is less than 100 Hz) or 0.25 Hz (if the maximum speed is greater than or equal to 100 Hz). Unless disconnected from the power source, the drive is intended to operate at a predetermined minimum speed. Refer to the user manual if the application requires zero speed operation without disconnection. Maximum speed is the F-04 parameter on the SP500 drive. This parameter has a range of 30-240 Hz and a step size of 0.1 Hz (if the maximum speed is less than 100 Hz) or 0.25 Hz (if the maximum speed is greater than or equal to 100 Hz). The maximum speed is the maximum output frequency value. Current limit is the F-05 parameter on the SP500 drive. This parameter allows for limited motor output torque during run or acceleration. The step size is 1.0% for the range of 10% to 150% of the rated controller current. An overcurrent fault may occur if the current limit is set too low. When output current attempts to exceed the preset current limit, motor speed is maintained or reduced, or deceleration time is extended.
