About the 790.46.00
This Reliance Electric drive hails from the industry-respected GV3000 series of automated drive from Reliance Electric. As part of a legacy series, this drive may have been manufactured past the discontinuation of Reliance Electric GV3000 products, and may have been assembled by Baldor, Rockwell Automation, or ABB. The instruction manual that corresponds with this specific drive is available online in Reliance Electrics' manuals D2-3426 & D2-3427. It is important to note that this specific GV3000 series legacy drive is characterized as a bookshelf-style drive, given its small stature. The 790.46.00 model drive is available for both repair and replacement here at AXcontrol.
Hardware Tips and Specifications
The Reliance Electric drive 790.46.00 is from the GV3000 series of bookshelf drives. The enclosure type on the drive is IP20 which indicates that the enclosure is not water-tight but can protect the drive against solid objects greater than twelve millimeters. Two voltages are associated with the drive, one being an input voltage and the other being an output voltage, both voltages have the same range of 380 to 460 VAC. There are two different output amperages associated with the output voltage depending on the chosen regulation. For V/Hz (volts/hertz) regulation, the output is 240 A at 2 kHz. The horsepower of the 790.46.00 drive is 100-125 HP.
A terminal strip is available on the 790.46.00 model, and can provide multiple important connections from the drive to:
- Customer input/output (I/O) devices; the terminals used for customer I/O devices are status relay connections at terminals 28-31
- Snubber resistor braking control connections at terminals 26-27
- Twenty-four volts of direct current inputs connections at terminals 16-25
- Analog torque/speed reference connections at terminals 12-15
- Analog output connections at terminals 10-11
- Encoder connections at terminal 4-9
- and finally RS232 connections at terminals 1-3
Software Tips and Specifications
On the front panel of the 790.46.00 drive, there is a keypad, this keypad also has a display that is used to display the alarm, faults, and errors that have occurred on the drive. Both the fault and alarm conditions are indicated by a two- or three-letter code that will flash on the display screen. One of the alarm codes is denoted by S-Ac which describes that the vector regulator’s self-tuning is active meaning that the vector regulation is in progress and enabled. To turn the alarm off allow the vector self-tuning to run its course and then press the stop/keypad button on the keypad to cancel the vector self-tuning process.
For more information on the 790.46.00 bookshelf drive refer to the D2-3426-2 GV3000/SE AC General Purpose (Volts/Hertz) and Vector Duty Bookshelf Drive Software Start-Up and Reference Manual or the D2-3427-3 Hardware Reference, Installation, and Troubleshooting Manual which provides an overview of the bookshelf drives and all parameters, alarm codes and faults.
Compatibilities
As a GV3000 legacy series drive, it is possible that the 790.46.00 drive has been manufactured by Reliance Electric, Baldor, or ABB. While this is true, the regulator version for the 790.46.00 drive can be identified through its American part number 240ER4060, which designates a drive regulator version of 6.0. AXcontrol is happy to offer a number of 6.0-version compatible regulator boards for this 790.46.00 model, including:
