### Question #: 13644

Question:
**
I need the drive setting for the 1.5kw spindle drive to work with the spindle motor where do I find them
**

**
**

**If you purchased the spindle from us, you should have received a little booklet that shows all of the program settings. If you did not receive that booklet, please call us so we can send you this booklet.
If you have the booklet, please let us know specifically what setting you would like to set and we can help.**

### Other Possible Solutions to this Question

**I have a water cooled spindle I only need the VFD drive. Does the VFD come with instrutction on hooking the VFD to Mach3?**The VFD does come with a manual that details the wiring and connection specifications, terminal features and a list of the parameters. There is no information on how to connect it to Mach3. It does detail the specifications within the parameters and terminal features on the analog input that is used with Mach3 and other control programs.

The conversion ratio is about 746 Watts = 1 Horsepower. Therefore your 5hp motor is equivalent to about 3,730 Watts. The kW designates kilowatts, or units of 1,000 Watts. So a 1.5kW inverter can supply only 1,500 Watts. Our larger inverter supplies 2.2kW, but you need a minimum of 3.7kW for your application.

Do you guys configure any of the setting in mach3 or will I need to do that all myself?**The redLeaf CNC computer systems will have either Mach3 or LinuxCNC installed as per the customer's request. If the Mach3 license is purchased, the license file will also be installed on the redLeaf CNC computer system.

The Mach3 or LinuxCNC settings will be configured during the assembly of the system. We contact the customer to determine the drive (mechanics) and inertial (weight of gantry and other parts of the gantry) specifications in order to correctly configure the steps per inch, velocity and acceleration.**Click the link to add information to this solution:**

Interested in the 110v 1.5kw spindle and vfd. Need an er16, or preferably an er20 collett. Would this item work.**I need the calculation to determine the stepper motor torque to find the load that it can lift using a lead screw at 1/2" diameter with 13 TPI.**There are two main questions that we can answer with respect to motor torque and the mechanical advantage of lead screws, 1) What torque motor do you need to lift a particular weight, or 2) What maximum weight will my motor torque be able to lift.

This formula uses Newtons (N) as it's final unit. Use this with the included radius (R) to determine the torque. Newtons can easily be converted to lbs or ounces using online conversions.

Effort = Sf + (Load/(2 x pi x (R/p) x Se))

where:

p = pitch of the screw

Se = screw efficiency = Standard lead screw will be between 20% (.2) and 40% (.4)

Sf = static force. This is the force that is needed to start the movement. The number may be eliminated, but it is good to use a number in the 5 N to 20 N range.

Load = the expected load that the effort will need to carry (i.e., the router and the included axis assembly that the motor will need to lift)

R = radius of the lead screw

This formula is based on the "law of the machine"

The final effort amount with its unit of newtons and R will be the torque. For example, if the effort comes to 100 N (newtons) and the R is .5 inches, then you can assume that the effort is 50 N-in since it would take twice the effort to turn form the one inch mark from the center of the shaft.

Example:

Load = 90 N (20.2 lbs)

R = 1 inch since that is the length from the center of the shaft that the motor is rated

p = 1 inch / 13 = .08 inches

Effort = 5 N + (90 N / (2 x 3.14 x (1 / .08) x .2))

Effort = 5 N + (90 N / (6.28 x 12.5 x .2))

Effort = 5 N + (90 N / (15.7))

Effort = 5 N + (5.73 N)

Effort = 10.7 N = 2.4 lbs = 38.4 oz-in

I am putting the oz-in on the end because the formula considers the distance from the center of the shaft to be one inch.

Therefore, a 425 oz-in motor would be able to lift a 20.2 lb Router with its accompanying assembly. If the assembly and router is heavier, plug in the numbers and determine the effort required.

With a bit of algebra, the formula can be rewritten to find the load:

Load = (Effort - Sf) x (2 x pi x (R/p) x Se)

Another formula that does not consider friction at all:

Effort = (Load x p) / (2 x pi x R)

Lets see if we get similar results:

Effort = (20 lb x .08 inches) / (2 x 3.14 x 1)

Effort = 1.6 / 6.28 = .255 lbs = 4.08 oz-in

The results from both formulas appear to be very small because a 13 TPI screw will have enormous mechanical advantage.

It is evident that the first formula that does consider friction that we are loosely estimating is far more conservative than the second formula. Either way, even the most conservative formula shows that the 425 oz-in motor will handle very large weights. If you are using a lead screw with only two turns per inch, .5 inch pitch, you can determine the requirements with the first formula.

Example for a 10 TPI 5 start (2 turns per inch) lead screw:

Load = 90 N (20.2 lbs)

R = 1 inch since that is the length from the center of the shaft that the motor is rated

p = 1 inch / 2 = .5 inches

Effort = 5 N + (90 N / (2 x 3.14 x (1 / .5) x .2))

Effort = 5 N + (90 N / (6.28 x 2 x .2))

Effort = 5 N + (90 N / (2.512))

Effort = 5 N + (35.83 N)

Effort = 40.828 N = 9.18 lbs = 146.88 oz-in

If your spindle speed is controlled by an analog signal, (for example, by a VFD with a 0 to 10 volt signal) and you’re using a DAC card like the m5i20 to output the control signal:

First you need to figure the scale of spindle speed to control signal. For this example the spindle top speed of 5000 RPM is equal to 10 volts.

10 volts / 5000 RPM = .002 volts / 1 RPM

If you need a spindle enable signal, link your output pin to motion.spindle-on. To link these pins to a parallel port pin put something like the following in your .hal file (net spindle-enable motion.spindle-on => parport.0.pin-14-out), making sure you pick the pin that is connected to your control device.**Click the link to add information to this solution:**
