DS308 AC Drive Simple Operating Instructions and failures11/21/2016When you have a drive fail, to be able to properly troubleshoot it, you first must know what the proper operation looks like to know when it is not functioning correctly. At least for most failures this is the case.The Magnetek DS308 drive is an AC drive that requires an input voltage of 230 volts. It has no option to be used with 460 volts. The drive chassis should be mounted on a surface that allows adequate air circulation and has proper ventilation. The motor should be connected to terminals T1, T2, and T3. Be sure to connect the input line voltage to terminals L1, L2, and L3 only. Applying voltage anywhere other than these terminals may result in damage to the drive and possibly personal injury. If power is incorrectly applied to other terminals, the most likely damage would be a blown bus fuse and probably a bad IGBT. Fortunately we are able to repair such damage.When power is correctly applied, the keypad will display F00.00. The Drive, FWD, and Stop lamps are on. Press and hold the Jog button noting the direction of motor rotation. If it is incorrect, remove power, switch wires between T1 and T2, the re-apply power. NOTE: The drive in this discussion is setup for keypad (local) operation of control and speed reference with maximum frequency of 60Hz, and the display readout set for output frequency. If your display or results differ, check the parameter settings related to these functions as they can affect what is observed. A value of 60 in the F00.00 display represents full speed for most common motors. Press the Run key and the Run lamp lights. The Stop lamp will flash, indicating the DS308 VFD is running at zero speed. To increase the speed of the motor (frequency) press the up arrow until the desired value appears then press Data/Enter. The drive will then respond to the change in speed. Reversing can be selected while the drive is stopped or while running. With the drive stopped, press the Fwd/Rev key. The Rev lamp will light and the Fwd light will go out. If the Rev key is pressed while the drive is running, the drive will decelerate to zero speed then accelerate to the same speed in the opposite direction.While the DS308 drive is stopped, to display different drive functions, press the Displ button to select between available functions. If these actions fail to occur or a fault is indicated when running the drive, the problem may be as simple as a missing input. However if everything is connected as it should be, you may be looking at a bad power board or a bad control board.Drive faults are displayed if an unacceptable operating condition exists. The keypad will display a code to indicate the specific fault condition such as Ou for over voltage, Uu for under voltage, and OC for over current just to name a few. If a fault occurs during operation, the drive will trip, the motor will come to a stop, and the fault code will be displayed. Consult the operator’s manual for a full list of fault condition codes.So in conclusion, if your Magnetek DS308 AC controller is not operating as it should, call on us. Whether the drive has no power, or has power but no output, or just won’t drive the motor, the drive repair specialists at Precision Electronic Services, Inc. can get you fixed up.
