Product Description

The 2MT3000 is a DeviceNet Option Card developed by Reliance Electric and Horner Electric to be used with the GV3000 series. The GV3000 series is built for motor control, monitoring, and regulation. The two setups of control for the GV3000 line include vector regulation and voltage/frequency regulation. Reliance Electric no longer has the GV3000 series for sale, but AX Control also has several of these units in stock. 

The 2MT3000 model was designed as an option board that will connect to GV300 drives while the model can be used with GV3000 drives, it can also be used with LiquiFlo AC modules, which were also produced by Reliance Electric.

The 2MT3000 DeviceNet Option Card is designed as a standard PBC, built to be integrated into the unit underneath the regulator board. To connect these two boards, attach a flexible ribbon cable to the parallel bus port.

Much like the regulator board, the 2MT3000 is outfitted with its own microprocessor. It is able to connect to one port of its dual memory, while the other port is able to grant a connection to the regulator board. The 2MT3000’s microprocessor is able to run diagnostic tests on the CPU, EPROM, RAM, and dual port memory.

There are two manuals associated with the 2MT3000 module; one is the D2-3411-8. The D2-3411-8 model gives limited information on the optional kit. The other is the HE-HGV3MT which is the part-specific manual for the 2MT3000 kit, but it is difficult to obtain.

Frequently Asked Questions about 2MT3000

How does the 2MT3000 unit operate with GV3000 or LiquiFlo drives?

Unfortunately, due to the lack of documentation, it is unclear how the 2MT3000 and associated drives will work together. It can be assumed that the 2MT3000 model will add an expansion to the GV3000 or LiquiFlo drives. Information on the operation of the LiquiFlo drives will be found in the manual attached above.

If I only have the D2-3411 Manual when using the 2MT3000 model, will that be enough information on installation procedures?

Unfortunately, the D2-3411 manual will not provide any information regarding the installation procedures with the 2MT3000 unit and GV3000/LiquiFlo drives. If wanting a manual that can encompass the entirety of installation procedures, potential troubleshooting, and other features, the best manual to use would be the HE-HGV3MT manual which only focuses on this option board and how it operates. 

Are there any connectors on this model?

Yes, there is only one available connector which is located on one edge of this board. The connector is a 15-pin female connector. A ribbon cable is used to connect this board to the preferred drive.

Reviews For 2MT3000

Internal Review

The biggest downside when it comes to this unit is the lack of documentation. The lack of documentation hinders the installation of the model, as it is unknown how the kit will be attached to the GV3000 or LiquiFlo drives. While there is a lack of documentation, there is no lack of availability of this model, and it is ready to purchase from AX Control today. - AX Control Tech
