About the 1SU44003

1SU44003 is an SP500 drive that is manufactured by Reliance Electric. This drive has a rated horsepower of 3.0 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).

Acceleration is the F-01 parameter on the SP500 drive. This parameter indicates the amount of time that the drive takes to ramp from a stopped position to the drive’s programmed maximum speed setting. The range for this parameter is 0.5-30 seconds, wherein the step size within the range is 0.1 seconds. An overcurrent IET condition may occur if the acceleration rate is set too fast. Deceleration is the F-02 parameter on the SP500 drive. This parameter indicates the amount of time that the drive takes to ramp from the drive’s maximum speed setting down to a stop. Both the deceleration and acceleration time are both proportional to the last set frequency. A high bus fault may occur if the deceleration rate is set too fast. RPM at base speed is the F-08 parameter on the SP500 drive. The range is 1-9999 and the step size is 1.0 unit. This feature provides the ability to scale the display by using the RPM display mode, to any desired engineering unit to match an application.
