About the 20V2150
The 20V2150 was released as a portion of the GV3000 series of AC Drives that was initially put out through Reliance Electric. This drive is 200-230 VAC and 20HP. Depending on when it was in production, this part may have also been produced and sold by Baldor Reliance or ABB. This drive is the 5.0 version of this drive. It is not being maintained by Reliance or any of the other manufacturers anymore, but AX Control does strive to keep it in stock.
With a power ranking of 29.8 KVA and 200-230 VAC, the 20V2150 has an input amperage of 75 amps and an output of 69.6 amps. It has a full load power loss of 600 watts. This drive has the means to switch between V/Hz or vector regulation. When this drive is using V/Hz regulation, it has the power to easily maintain an output current rating of 110%. When it is regulating the vector, this drive is capable of achieving an overload for 1 minute that is 150% that of normal.
The 20V2150 is covered by a standard NEMA 1 style enclosure. It has a vented chassis and has an access panel that allows the operator to access an RS-232 communication port with no need to remove the enclosure cover. This drive should only be used in indoor applications. Within this enclosure, there are interior components that complete the drive. These include a GVPB board, regulator PCB, dual-fan assemblies, keypad and bracket, PISC board. The regulator board comes mounted to the back of the keypad assembly using the bracket that is attached to it.
While the keypad assembly-mounted regulator board standard with the 20V2150 drive may be convenient and accessible, on occasion it may induce a frustrating fault in the drive's function. One such fault that may occur as a result of this drive's regulator board mounting exists in the missing power module ID fault, which is always conveyed through the appearance of the fault code PUc on the drive's built-in display interface. This fault can be caused by a faulty or disconnected cable extending from the drive's regulator to the drive's power module. Proper correction of this PUc fault includes a simple check of the cables connecting 20V2150's regulator board to its power module.
