Dimensions and Assembly

The Nix Servo Drive is available in 4 versions, each one with different specifications and dimensions:

  • NIX-x/xx-y-C (Nix with onboard connectors)
  • NIX-x/xx-y-P (Nix with gold plated pin headers)
  • NIX-x/xx-y-Q (Nix with Quick connector board)
  • NIX-x/xx-E-C (Nix with EtherCAT)

Fixation elements diameter ≤ 6 mm

Please do not use spacers, washers or nuts exceeding 6 mm external diameter as they could collide with some electrical parts.

Also, take due precautions not to damage any components during assembly.

NIX-x/xx-y-C (Nix with onboard connectors)

Nix Servo Drive version NIX-x/xx-y-C has a 60 mm x 75 mm footprint and a maximum 14.5 mm height. The drive is provided with 4 x Ø 3.2 mm holes for M3 standoff mounting to the drive plate and to allow mounting the EtherCAT Daughter Board and the IO Starter Kit. These holes are plated and connected to protective earth (PE). The drive plate is provided with 4 x Ø 3.2 mm M3 holes for fixing or heatsink mounting (if needed). 

Next figure shows mechanical dimensions in mm. Tolerances ≤ ±0.2 mm.

NIX-x/xx-y-P (Nix with gold plated pin headers)

Nix Servo Drive version NIX-x/xx-y-P has a 60 mm x 75 mm footprint and a maximum 19.4 mm height. The drive plate has 4 x Ø 3.2 mm M3 holes for fixing or heatsink mounting (if needed). 

Next figure shows mechanical dimensions in mm. Tolerances ≤ ±0.2 mm.

NIX-x/xx-y-Q (Nix with Quick connectors board)

Nix Servo Drive version NIX-x/xx-y-Q has a 60 mm x 75 mm footprint and a maximum 31.1 mm height. The drive plate has 4 x Ø 3.2 mm M3 holes for fixing or heatsink mounting (if needed). 

Next figure shows mechanical dimensions in mm. Tolerances ≤ ±0.2 mm.

NIX-x/xx-E-C (Nix with EtherCAT)

Nix Servo Drive version NIX-x/xx-E-C has a 60 mm x 75 mm footprint and a maximum 23.6 mm height. The drive plate has 4 x Ø 3.2 mm M3 holes for fixing or heatsink mounting (if needed).

Next figure shows mechanical dimensions in mm. Tolerances ≤ ±0.2 mm.

Assembly Instructions

The assembly of the plate to a cooling surface is essential to achieve desired performance. Due to the dimensions of the plate, it is essential that the thermal pad is soft enough to compensate the flexing during assembly. Next are some thermal interface materials suitable for the Nix.

Heatsinks

In order to choose the cooling needs of the Nix, please see the thermal calculations in Dimensions and Assembly page.

Please use appropriate thermal interface materials and follow the assembly instructions to achieve an excellent heat transfer. See below 👇.


Thermal interface material

Thermal interface materials for a cooling plate with a big surface should be tacky and soft to prevent the formation of air bubbles.

Please note that thin "high performance" materials that look promising on the datasheet may end up with poor heat transfer. With thin materials the pressure is only applied near the screws and air bubbles are formed, decreasing the heat transfer dramatically.
