About the 1SU41007

The 1SU41007 is an SP500 drive that is manufactured by Reliance Electric. This drive has a rated horsepower of 7.5 HP and is contained in a NEMA 1 or chassis style enclosure. The rated voltage is 380-460 VAC. The dimensions of Enclosure C, which contains 1SU41007, are 357.8 mm (14.1 in) (H) x 158.2 mm (6.2 in) (D) x 278.1 mm (10.9 in) (W).

The user can identify faults on the drive with the provided fault codes. A few of the potential fault codes are listed as follows: PUc is the code for the Missing Power Module ID connector fault. This fault is caused by a bad or disconnected cable between the Regulator and the Power Module. In order to correct this fault, check the cables between the Regulator board and the Power Module. PUn is the code for the Power Module not identified fault. This fault is caused when drive parameters have been restored to power-up defaults and/or the regulator has not been configured to match the power module. PUo is the code for the drive power electronic overload fault. This fault is caused by an overloaded power module and/or a DC braking current or torque boost that is too high. In order to correct this fault, check the load on the power module, the power module size v. its application, the DC braking current value, and the torque boost. SF is the code for the self-tuning status (vector only). In order to clear this condition, see parameter U.009.
