Product Description

Model number 0-56926-50 is a replacement current feedback board used with the GV3000 drives from Reliance Electric LTD. These devices were manufactured and produced as items from their electromechanical series of products. When the 0-56926-50 board has been inserted into the chosen GV3000 drive, it must be noted that it can only work with drives that operate on one, two, three, or five HP at 460 VAC drives. 

The 0-56926-50 Current Feedback circuit board is designed for the feedback signals of the GV3000 drive’s microprocessor to be accepted and processed. The 0-56926-50 can accept the data and the adjustable external speed reference signals provided by the GV3000 drive’s encoder module attachment as well.

The 0-56926-50 then sends the received feedback signals to be processed by the GV3000 Drive’s isolated drive modules, a component of the other printed circuit board, the Gate Driver PCB unit. Once the drive modules process the feedback signals, the IGBTs create a pulse width modulated waveform corresponding to the speed or frequency (this depends on the vector regulation method selected, either sensorless vector control or flux vector control).

Prior to installation, the 0-56926-50 board needs to be double-checked and properly functional before installing the GV3000 drive, as it may cause the unit to become damaged by the electrical power intake upon starting it.

There is only one readily available manual that can be used when installing the 0-56926-50 board, which is the VTAC 7 D203372 User's Guide. This manual includes how the current feedback board will be used with GV3000 drives in conjunction with the regulator board. 

Frequently Asked Questions about 0-56926-50

There are two versions of current feedback replacement boards, this unit, 0-56926-50, and the 0-56926-20 unit; are there any differences between the two?

According to the D2-3372 manual under Table 11.4, which denotes the replacement part for 1-5 HP at 460 VAC drives, the 0-56926-50 and 0-56926-20 models are essentially the same. The 0-56926-20 may be used with smaller drives such as 1 and 2 HP drives whereas the 0-56926-50 board is used with 3 and 5 HP drives. More information on the differences would be best coming from Reliance Electric or associated documentation to the 0-56926-50 board, and the GV3000/VTAC7 drives. 

The 0-56926-50 model is used with a regulator board; how is it used with the regulator board?

The 0-56926-50 board is used with a regulator board by working with the control loop output, which will send PWM gating signals through the 0-56926-50 model to the associated isolated drives on the gate driver board within the GV3000 drive. 

Reviews For 0-56926-50

Internal Review

One of the downsides of the 0-56926-50 model is that information is limited; it is known that it is a current feedback board and what drives it can be used, but the information about how it will be installed is limited within the D2-3372 manual. - AX Control Tech
