About the 1SU54003

1SU54003 is an SP500 drive that is manufactured by Reliance Electric. This drive has a 575 VAC and is enclosed in a NEMA 4X (indoor only)/NEMA 12 enclosure. The horsepower rating is 3.0 HP. This SP500 drive is contained in a size B enclosure. 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).

A number of fault codes help the user identify faults on the drive. EL is the code for the encoder loss fault. This fault is caused by the drive not detecting feedback from the encoder. In order to correct this fault, check the connection between the encoder and the drive, and check the coupling of the encoder and the motor. FL is the code for the function loss fault. This fault is caused by opened function loss input on the control terminal. In order to correct this fault, check external interlocks at terminal 16 and terminal 20. HId is the code for the high time identification aborted fault. This fault is caused when the identification process for V/Hz has been aborted. In order to correct this fault, check H.019 for the identification result. HIL is the code for the high line voltage fault. This fault is caused by an input voltage that is more than 15% above the nominal input voltage. In order to correct this fault, the user must check the actual line voltage against U.018 or H.021.
