About the 1SU44005

1SU44005 is an SP500 drive that is manufactured by Reliance Electric. This drive has a rated horsepower of 5.0 HP and is contained in a NEMA 4/12 enclosure. The rated voltage is 380-460 VAC based on the drive model number. 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). Enclosed drives such as the NEMA 4/12 have to operate between 0° to 40° C (32° to 104° F).

IET Output Enable is the F-09 parameter. When this setting is off, this is an indication that the controller is running. When this setting is on, this is an indication of an IET fault. The fault will remain until it is cleared by the user pressing the “STOP/RESET” key (in Local operation) or by using the remote IET reset signal (for Remote operation). Carrier Frequency is the F-10 parameter. This setting ranges from 4-8 KHz and helps compensate for acoustic noise, heating, and other current problems by adjusting the switching frequency of the transistors in the inverter section. This setting also controls the width of the pulse and keeps the current smooth to the motor. A carrier frequency at 4 KHz maximizes the drive’s continuous power rating. Increasing the carrier frequency alleviates acoustic noise but may derate the controller in some applications.
