GE FujiAF-300 Keypad Operator Interface, 6 Dual-Function Keys, LCD Display, Remote Capable

Product Description

What this part is

A GE Fuji 6KM$2KP1 keypad operator interface panel for the AF-300 family of inverter drives. It is the local operator interface: the thing you set frequency and parameters on, start and stop the drive from, and read faults off. It was sold as an option because a good many AF-300 Micro-$aver II drives, particularly the NEMA 1 enclosed units, shipped without a keypad as standard.

Correcting the source data

Earlier copy sold this as a controller panel for monitoring and controlling various industrial processes. It is narrower than that and more useful for being narrow: it is a drive keypad, and it works with GE Fuji AF-300 inverters. It is not an HMI you can point at a PLC, and it will not talk to another manufacturer’s drive.

Decoding the part number, and one number that is not a rating:
6KM — GE’s order-number group for the GE Fuji AF-300 drive family and its accessories. The dollar sign in 6KM$2KP1 is a genuine character in GE’s numbering, not a typo, which is why the part is also written 6KM2KP1 and 6KM-2KP1.2KP1 — the keypad option itself. KP reads as keypad.
Worth stating plainly because it causes real confusion: the 300 in AF-300 is the product family name, not a rating. It is not 300 horsepower, not 300 volts and not 300 hertz. AF-300 Micro-$aver II drives covered roughly the 1/4 to 5 HP range, and this keypad carries no power rating of its own at all — it is a signal-level interface.

Installation and setup notes

Isolate the drive and allow the DC bus to discharge before fitting or removing the keypad; the bus stays charged after the display goes dark. Fitting a keypad does not by itself hand it control — on AF-300 drives the command and frequency reference source is a parameter, so if the drive is currently set for terminal-strip run/stop and an analog reference, the keypad’s run and stop keys will do nothing until you change that. Decide deliberately which source you want and prove the stop path before running a load. If you are remote-mounting, use the correct extension arrangement and keep the run to a sensible length; a keypad cable routed alongside motor leads will pick up drive noise and give intermittent display faults.

Quantity and configuration

One keypad panel. Not included: the drive itself, remote-mounting kit or bezel, extension cable, panel cut-out gasket, mounting screws and the drive manual.

Interchange guidance

This is the keypad option for the AF-300 family and is the natural companion to AF-300 Micro-$aver II drives ordered without one — for example the 6KM$243001N1A1 and 6KM$243005N1A1 NEMA 1 units. Fuji’s own equivalent operator panels for related inverter generations, such as the TP-G9S, are a different part from a different range and should not be treated as a straight swap. Also written 6KM2KP1, 6KM-2KP1, 6KM 2KP1, 6KMS2KP1 and 6KM$2KP-1, and listed under both the General Electric and Fuji Electric names.
