Product Description
This drive, as part of the Reliance Electric GV3000 series of automated drive, may also be known by its European part number 896.03.11, and has since been discontinued by its original manufacturer. While this may be the case, a number of trusted retailers have stepped up in the years since 2009 to resume production of this particular drive. Depending on the year it was manufactured. this 55ER4060 drive may have been put out by companies including Baldor Electric, ABB, or industry giant Rockwell Automation. While somewhat more available than higher-voltage GV3000 series drives without CE filters, the discontinued status of the original GV3000 series does ensure some degree of market volatility. We are very much happy to offer this drive for both purchase and repair through AXcontrol.com, with a standard lead repair time of one to two weeks, and a guaranteed two-year warranty upon purchase.
Hardware Specifications
Reliance Electric’s Bookshelf Drive number 55ER4060 is a drive that operates without a CE filter, on a V/Hz current of 5.5 amperes. There are two available regulator versions on this model which are a vector regulator and a V/Hz regulator which stands for volts/hertz. The typical voltage range used to operate this model is three hundred and eighty to four hundred and sixty volts. This model also has a unique European stock number which is 896.03.11, the 03 in the stock number indicates the power module size. The last number in the code, which in this case is 11 indicates the terminal and transistor circuit type for this model, which are DC bus terminals and a braking transistor circuit.
During the operation of the 55ER4060 drive input line branch circuit protection fuses are vital to ensure that the input power lines are fully protected. The AC input current for this model, which is dependent on the total line impedance, will be at an amperage of ten; the nominal external fuse allowed for the 55ER4060 drive is sixteen amperes with a maximum of twenty-five amperes.
A braking resistor is required when operating the 55ER4060 bookshelf drive, there are two braking power settings associated with this drive which are twenty-five percent duty cycle and continuous, both of these braking powers are four and a half kilowatts. The turn-on braking power voltage is seven-hundred and fifty volts with the turn-off braking power voltage being seven-hundred and twenty volts. The minimum allowed external braking resistor associated with this drive is one-hundred and twenty-five Omega.
Software Specifications
As with the majority of GV3000 series Reliance Electric drives, the 55ER4060 drive can run under either volts/hertz or vector regulation control patterns. While this drive is equipped with a default volts/hertz regulation system, the customizable parameter P.048 allows the drive user to select either type of control, accessible through the drive's extensive second menu of programmable parameters. The drive user may need to enter a factory-supplied second menu password to access the second menu of drive parameters. This entire process is relatively streamlined, and should take about five seconds in total.
As with any refurbished or vintage drive, this GV3000 series legacy model may come across the occasional hiccup in normal function, known as "faults" to the educated drive user. Outlined conveniently in Reliance Electrics' GV3000/SE AC Drive Software Reference Version 6.06, a number of faults may impact the 55ER4060 drive at an elevated rate due to its lack of a CE filter. One such fault particularly relevant to owners of this specific drive is the Earth current failure fault, designated on this drive's built-in keypad by the simple fault code EC. The Earth current failure fault happens with a concurrent unintentional grounding of the drive's output. Corrective action for this fault includes checking for correct isolation between 55ER4060's ground and output terminals. If the problem is not found with these terminals, various drive sensor replacements may be necessary. A more in-depth description of fault codes and programming specifications for the 55ER4060 drive is available online in Reliance Electrics' GV3000/SE AC Drive Software Reference, Version 6.06.
Compatibilities
Although this GV3000 series drive sports somewhat of an unique model number, considering its inclusion of "ER," this product is identifiable nonetheless as a drive with a 6.0 regulator version. This updated 6.0 regulator version lends itself well to some of our additional offerings at AX control, as we offer a wide variety of printed circuit and regulatory boards. A few 6.0-version regulator boards compatible with the 55ER4060 drive's 55 HP rating, and available for purchase include:
