1.5kw spindle and inverter

1.5kw spindle and inverter

The inverters change all the time and it’s almost impossible to keep up. The instructions below will work for most inverters. We are not responsible for anything when you wire your inverter and use this instruction on your own risk.

Note that there is yet another model that is similar to the image above but with a turning wheel for speed. Connect it in the same way as below, but it must be programmed afterwards. This is easy, just check the instructions and follow the “User settings” that they list among parameters. Press PRGM or SET and scroll to any PD code and fill in requested “User settings”. In the setting for how many pins your motor has, enter “3” DON’T RUN THE SPINDLE BEFORE YOU HAVE SET THE PARAMETERS.

There are different versions of spindles and inverters. If you look at the pins on the spindles, you’ll see what kind of spindle you have.

Grounding
The spindle has no pin for ground, so you have to ground it yourself. If you have metal clamps for the spindle, you can ground the entire chassis down to earth on your Power supply and then the spindle will be grounded at the same time. otherwise you have to somehow ground the metal casing on the spindle. The manufacturer does not think you need to ground the spindle but do it anyway.

To connect the spindle and the inverter, you will need standard 3-wire cable the same as you have for sockets for ordinary household electronics. As well as a grounded plugg. We do not include this because all countries have different standards and that this is strong current so we should not encourage you to do this without permission. You need about 2 meters from inverter to contact and about 4 meters from inverter to spindle

NOTE: There is strong current to both the invertebrate and the spider. You may not do this without permission or good knowledge. Let anyone who knows, perform this work and we are not responsible for any damages to electronics or personal injuries.

Sometimes the pins on the spindle determines which model you have.

If you have 4 pins then you probably have a Huang inverter like the one below. Otherwise, jump to instructions for “Settings for” 3 pin “inverter”

Settings for “4 pin” inverter
On the spindle itself, solder 3 wires on pins 1,2 and 3. The cable from pin 1 is to V in inverter and pin2 to W and pin 3 to U. Connect the socket according to Figure R, S and ground. When you start your spindle and it goes the wrong direction, just change location on two of the cables in U, V or W

Some times this type of inverter needs some more settings, enter and change a couple of parameters
Press PRGM and scroll to the following PD code and fill in the following.
PD004: 400
PD005: 400
PD143: 3
PD144: 3000

Settings for ”3 pin” inverter

Note that there is yet another model that is similar to the image above but with a turning wheel for speed. Connect it in the same way as below, but it must be programmed afterwards. This is easy, just check the instructions and follow the “User settings” that they list among parameters. Press PRGM or SET and scroll to any PD code and fill in requested “User settings”. In the setting for how many pins your motor has, enter “3”

On the spindle itself, solder 3 wires on pin 1.2 and 3. The cable from pin 1 is to V in inverter and pin2 to W and pin 3 to U.
The socket connects to R, S and ground. When you start your spindle and it goes in wrong direction, just change location on two of the cables in U, V or W

This inverter is usually ready to go and you can start it right away. You should increase speed at start and stop for spindle to about 20 seconds, default is about 60 seconds which is unnecessary long.

 

Start the spindle
To start the spindle, press Run and stop. The “for” lamp means that the cutter rotates in the correct direction while “Rev” rotates the cutter in the other direction. Keep an eye on this so that the spindle does not rotate in the wrong direction when cutting your pieces.
If you want to change the speed of the spindle, you can choose between 0-24000 rpm. The ca 10-12,000 turns are good for aluminum and 18000 turns are good for MDF with a cutter that is 5-6mm.

Experiment until you find the right speed to what you cut.
