KXF0DXEMA00 Panasonic Z Axis Motor CM301 SMT Spare Parts

Product Overview

The Z-axis motor is the vertical drive behind the placement head on a Panasonic CM301 SMT pick and place machine. It is the unit that positions each nozzle through the placement cycle, so every component the head places depends on this axis. This is the replacement part for that position, supplied for maintenance teams who need a stopped head back in production. It is a like-for-like unit rather than an upgrade: the same drive, the same place on the head, the same part you are removing. Buyers are usually SMT maintenance engineers, line supervisors and repair workshops who need a confirmed match quickly and a motor that behaves like the original in production.

Specifications

Z-Axis Motor Function

• Height control: the motor sets how close the nozzle comes to the board before release, which decides whether a part seats flat or sits high on its pads.
• Contact and release: the same stroke governs how the part is released onto the paste, so a hesitant motor shows up as scattered placements on one head rather than a machine-wide fault.
• Repeatability: the head cycles continuously through a shift, and small changes in the motor build up as growing variation across a board instead of one obvious failure.
• Built for the position: this is a Z-axis drive, not a universal motor, and it matches the mounting and connector arrangement that pick and place machine manufacturers specify for this axis. Compare it with the unit you take off before ordering.

Fault Signs and Replacement Timing

A Z-axis motor seldom stops without warning. The first signs are usually small: placement height drifting out of tolerance, parts sitting high or slipping sideways before reflow, occasional pick errors from one head, or a Z-axis alarm that clears on reset and returns later in the shift. Some motors also run hotter or sound rougher than the other heads on the same machine. Because a head that cannot reach its height stops the line, many teams keep one replacement on the shelf rather than ordering against a stopped machine. If realignment brings the height back but it drifts out again soon afterwards, the motor is usually the cause rather than the program.

Replacement Steps

1. Isolate the machine at the mains and follow your own lockout procedure before opening the head.
2. Photograph the motor, its connector and the cable route so refitting is straightforward.
3. Unbolt the old motor, keeping the screws, shims and any coupling parts together, and compare the number on its housing with the part you ordered.
4. Fit the replacement in the same position, reconnect the cable along the original route and check the coupling or belt before closing up.
5. Power up, jog the head slowly and run a test placement on the pick and place machine to confirm the nozzle reaches the board cleanly.
6. Verify the Z height and zero point as your machine manual describes, then watch height consistency across all heads during the first production run.
