Overview
This installation manual is designed for Mitsubishi Variable Frequency Drives (VFDs) purchased from
MachMotion. It was written to interface VFDs with the Apollo I Breakout Board. It provides all the information
from wiring your VFD to troubleshooting it. Much of the wiring and many of the settings should already be
configured correctly for your spindle motor. However, all the information is provided in case you ever need to
disconnect or change something.
When the spindle is turned on inside Mach3, the Apollo I Breakout Board provides a 0-10V analog signal to the
VFD and turns on one of two relay contacts for clockwise and counterclockwise rotation. The VFD then scales
the analog signal to the maximum frequency of the spindle motor. For instance, if a spindle motor’s max
frequency is 60Hz, then 5V will give you 30Hz and 10V will give you 60Hz. The analog voltage is also scaled to the
max pulley speed inside Mach3. In the previous example, if the maximum pulley speed is 1000 RPM, then 500
RPM will make the VFD output 30Hz and 1000 RPM will make it output 60Hz.
If you purchased a drive enclosure from MachMotion, then all you have to do is set up your VFD parameters and
connect your spindle motor. Otherwise you will also have to wire up an enable circuit for your VFD.
We hope that this installation can be as quick and easy for you as possible. If you have any questions, please do
not hesitate to give us a call.
Sincerely,

Control Cable
The VFD control cable is the Cat5 cable that runs from the breakout board to the Mitsubishi VFD. From the
factory it is already wired correctly to the VFD. Plug the cable into the RJ45 connector labeled Spindle Control on
the IO6 Breakout Board.
If for any reason you need to disconnect the control cable from the VFD, the wiring is shown below.
Figure 1 Control Cable

6 | P a g e
Enable Circuit
To set up your VFD correctly, you only want power supplied to it while your control is enabled. Use the 24V
enable signal (24-EN) from the breakout board, a 24V relay, and a contactor as shown below. If you purchased a
drive enclosure, your enable circuit is already set up.
If your VFD is rated for your spindle motor (i.e. 3Hp VFD with a 3Hp motor), then anything above 3Hp must use 3
phase power. The blue dashed line in the diagram below shows the 3 phase wire.
Figure 2 Enable Circuit
When the machine is enabled, the 24-EN signal turns on. This turns on RC2 which then connects 230 VAC to the
coil of RC1. RC1 then turns on the power to the VFD. You can use the same enable circuit for your servo drives.

7 | P a g e
Spindle Motor
Connect your spindle motor to the terminals labeled U, V, and W as shown below. If your spindle moves the
wrong direction when you turn it on, just swap any two of the spindle motor wires.
Figure 3 Spindle Motor

Brake Resistor
If you want a brake on your spindle, you will need a brake resistor. Use the table below to locate the correct
resistor size. You can order them directly from Mitsubishi.
Motor (Hp) Re i tance (Ohm ) Continuou Power (W) Mit ubi hi Part #
1/2 200 60 FR-ABR-0.4K
1 100 80 FR-ABR-0.75K
2 & 3 60 120 FR-ABR-2.2K
5 40 155 FR-ABR-3.7K
7 1/2 25 185 FR-ABR-5.5K
10 20 340 FR-ABR-7.5K
If you have a brake resistor, connect it between PR and P/+ on the VFD.
Figure 4 Brake Re i tor
Note: Each VFD model is slightly different. Just make sure that you connect the resistor to the correct terminals
(PR, P +).

Pro rammin
To setup your VFD, you will have to learn how to program it. The VFD user interface consists of a small screen, 5
buttons, a few status LEDs, and a scroll wheel as shown below.
Figure 5 VFD U er Interface
To change any settings you must enter PU mode. Press the PU/EXT button once and the LED by PU should light
up. When you are finished changing the settings, you must put the VFD back into EXT mode by pressing PU/EXT
again. If the LED by EXT is not on, then the VFD will not work.
You can setup parameters by following the procedure below:
1. Make sure the VFD is in PU mode (LED by PU is on). If not press the PU/EXT button to turn it on.
2. Press the Mode button until you see “P 0”. This is parameter 0.
3. Use the scroll wheel to go to your parameter number (P18 for example).
4. Press the Set button once. The current value of the parameter should display.
5. Change the value by using the scroll wheel.
6. Press the Set button again. The screen will start to flash between the parameter and the value.
7. Repeat steps 3 to 6 until all your parameters are set up correctly.
8. Put the VFD back into EXT mode by pressing the PU/EXT button. Make sure that the LED near EXT is on.
9. Cycle the power to the VFD. Make sure to wait until the VFD completely turns off before repowering it.
Now you should be ready to run the VFD.
Note: If you see an Er1, Er , Er3, or Er4 error, make sure to put the VFD in PU mode before changing the
parameters!

10 | P a g e
VFD Setup
To setup your VFD you will need to know your spindle motor’s frequency. It is also helpful to know the
maximum current that your spindle motor should ever draw. You should be able to find both values on the
motor’s nameplate.
If you cannot locate the motor’s frequency, the name plate should tell you how many poles there are on the
motor. Using the motor’s maximum RPM and its number of poles, you can calculate the frequency with the
formula below.
Frequency = Max RPM * Number of Pole / 120
You are now ready to setup your VFD.
Standard Setup
Your VFD comes pre-programmed from MachMotion. The following parameters should never be changed.
Parameter # De cription Default
73 Analog Input Selection 10
74 Input Filter Constant 6
You may, however, have to change the following parameters.
Parameter # De cription Standard Range
1 Maximum Frequency (If less than 120 Hz) Max Motor Frequency 0-120Hz
2 Minimum Frequency 0 0-120Hz
3 Frequency Motor Frequency 0-400Hz
7 Acceleration Time 1-3 0-3600 Sec
8 Deceleration Time 1-3 0-3600 Sec
9 Max Motor Current Rated VFD Current 0-500
18 Maximum Frequency (If greater than 120 Hz) Max Motor Frequency 120-400Hz
72 PWM Frequency Selection 10 0-15
125 Maximum Frequency Max Motor Frequency 0-400Hz
All the frequency parameters (1 or 18, 3, and 125) will be the same value unless your maximum frequency is
different from the frequency on the spindle motor’s nameplate. Only set parameter 1 if your max spindle
frequency is less than 120 Hz. Only set parameter 18 if your max spindle frequency is greater than 120Hz.
If your spindle motor does not mention a minimum frequency, leave parameter 2 at zero. Also, if you cannot
find your max motor current, just set parameter 9 to the rated VFD current.

11 | P a g e
Parameter 72 may also have to be adjusted depending on how you VFD sounds. If it is very noisy or if it sounds
like it is grinding, you can try changing this anywhere from 0 to 15.
If you get a regenerative error, you can lengthen the deceleration time (parameter 8).
Auto Tuning
If your spindle is not working well, you may need to use auto tuning. Most systems will not need this.
Parameter # De cription Standard Range
71 Applied Motor 13 0,1,3,13,23,40,43,50,53
80 Motor Capacity Rated Motor kW 0.1-7.5kW
If you do not have a Mitsubishi spindle motor, just set parameter 71 to 13. Otherwise enter the motor code into
the parameter.
To auto tune your VFD, follow the instructions below.
1. Set parameter 96 to 11.
2. Press the Mode button until the MON LED turns on.
3. Press the Run button. You should see 12 in the display while the spindle motor runs. If the auto tuning is
successful, you will see the display change to 13.
4. Press the Stop/Re et button.
Auto tuning should now be complete. Make sure to exit PU mode! If your spindle is still not running well, please
call MachMotion at 573-368-7399.
Brake Resistor
For a brake resistor, you must set up two other parameters.
Parameter # De cription Standard Range
30 Regenerative Function 1 1
70 Special Regenerative Brake Duty 15 0-30%
You will have to experiment with the regenerative brake duty. If you get a regenerative error (E.OV1 through
E.OV3), then the duty is set too high. If your spindle does not stop fast enough, then the duty is too low.

12 | P a g e
Test Run
You can test your spindle motor directly from your VFD. Follow the sequence below.
1. Press PU/EXT to put the VFD into PU mode (make sure the PU LED is on).
2. Press the Mode button until the MON LED turns on.
3. Turn the wheel to set your frequency and press Set. The screen will flash between F and your frequency.
4. Press Run and the motor should begin moving.
5. Press Stop/Re et to stop the motor.
If it seems to be running well, you should continue by setting up Mach3. Make sure to exit PU mode!

13 | P a g e
Mach3 Setup
With your spindle wired and programmed, it is time to set up Mach3. You must enter in your maximum RPM for
the spindle motor so Mach3 knows how to scale the analog voltage output. If you have different gears, you can
set up multiple maximum speeds. Mach3 uses a different pulley for each different speed configuration. For
example, one pulley could be set to 75 to 300 RPM for a low speed (at 300 RPM the control will output 10V). A
medium speed pulley could go from 300 to 1200 RPM and high speed pulley could run from 1200 to 2400 RMP.
To change your pulleys, go to Config -> Spindle Pulley . The Pulley Selection window will appear as shown in
Figure 7.
Figure 6 Spindle Pulley
Figure 7 Pulley Speed Setup
Use the drop down menu titled Current Pulley to select the pulley you want to update. Enter in your maximum
and minimum speeds for each pulley. Then select the pulley you want to load and press OK.

14 | P a g e
You can also change pulleys by using M41-M45. The macros can be used to just change pulleys in Mach3, or you
could use them to automatically change gears on your machine. Outputs 12-16 are configured to shift between
gears 1 and 5. To shift your machine into neutral, run M40. Open up the macros with the VB Script Editor for
more details.
Mach3 should now be set up correctly.

Turnin on Your Spindle
To turn on your spindle, begin by setting up your spindle speed. Navigate to Prog Run and click on the Spindle S:
user input. Enter your speed and press Send as shown in Figure 8.
Figure 8 Setting up Spindle Speed
Note: If you don’t have the MachMotion screen set, spindle speed can be changed right on the main screen of the
Mill profile. Click on the user input, enter a new number, and then press enter.

Control the spindle by pressing the FWD and REV buttons. The button will turn red when you press it once.
Pressing the button again turns the spindle back off.
Figure 10 Spindle Button
Note: If you don’t have the MachMotion screen set, turn on the spindle by pressing the button Spindle CW F5.
When the button is flashing, the spindle should be on.

Stop
Test your spindle by commanding it to go half of the pulley’s maximum speed. If it is working correctly, your VFD
will be running at close to half of the maximum frequency. Next command it to move the pulley’s maximum
speed. Your VFD should now be running at the maximum frequency. If the frequency is very far off, check your
calculations and make sure that the VFD was programmed correctly. If it still is not correct, you may have to
calibrate your spindle.
If your VFD is not turning on or if it has a fault, see the trouble shooting section below.

17 | P a g e
Calibratin Your Spindle
For mo t y tem you can completely kip thi ection. If your IO6 Breakout Board is not outputting the correct
analog voltage, you can calibrate your spindle by using the procedure below.
There are two different methods to use depending on if you know the spindle speed or not. It is simpler to
calibrate your spindle if you know the speed.
Begin by finding the current velocity of your spindle. On the top menu bar select Config, then Motor Tuning. You
should see the Motor Tuning and Setup window as shown below.
Figure 12 Motor Tuning and Setup
On the right column titled Axi Selection, press the Spindle button. The spindle parameters will be loaded. Now
record the Velocity value located on the bottom right of the window. See the figure below.
Figure 13 Spindle Velocity Value
In Figure 13 the spindle’s current velocity is 1575.

18 | P a g e
With Spindle Feedback
If you have spindle feedback or a tachometer, you can use the shorter method to calibrate your spindle. Simply
find the values shown below.
Current Velocity
Use the velocity value found above from the Motor Tuning and Setup window.
Commanded RPM
Enter in a spindle speed as shown above. Then turn the spindle on.
Actual RPM
Record the actual speed either using a tachometer or another method of spindle feedback.
Now plug these values into this formula:
New Velocity = Current Velocity*(Commanded RPM / Actual RPM)
Your new velocity value should be fairly close to 1575. If not, check your calculation again.
With your new velocity calculation, go to the Motor Tuning and Setup window by selecting Config, then Motor
Tuning. Press the Spindle button and enter in your new velocity. Press SAVE AXIS SETTINGS before pressing OK.
Your spindle should now be calibrated.
Without Spindle Feedback
If you do not have a method to calculate your spindle speed, you can calibrate your spindle by using the
frequency of your variable frequency drive (VFD). However, you need to find the five different values as shown
below.
Current Velocity
Use the velocity value found above from the Motor Tuning and Setup window.
Pulley Max
Go to Config on the main menu bar, then select Spindle Pulley … You will see the following window:

19 | P a g e
Figure 14 Max Pulley Speed
Your current pulley will be selected. Your Max Speed value is your pulley max needed for the spindle calibration.
Max VFD Hz
The maximum motor frequency is your Max VFD Hz (assuming your VFD is set up as shown above).
Commanded RPM
Enter in a spindle speed as shown above. Then turn the spindle on.
Actual Hz
Your VFD should display the current frequency in Hz, which is the Actual Hz value.
With the above information, you are ready to calculate your new velocity. Use the formula below:
New Velocity = Current Velocity*(Max VFD Hz *Commanded RPM/Pulley Max)/Actual Hz.
Your new velocity value should be fairly close to 1575. If not, check your calculation again.
Now go to the Motor Tuning and Setup window by selecting Config, then Motor Tuning. Press the Spindle
button and enter in your new velocity. Press SAVE AXIS SETTINGS before pressing OK. Your spindle should now
be calibrated.

Trouble Shootin
If your spindle is not turning on, follow the procedure below.
1. Check the REV and FWD LEDs on the Apollo I Breakout Board.
a. Neither REV nor FWD ever come on:
i. Make sure your spindle is enabled (Config->Ports and Pins->Motor Outputs).
ii. Set the spindle’s Step Pin# to 1 and the Step Port# to 2 (Config->Ports and Pins->Motor
Outputs).
iii. Enable outputs 1 and 2, set both Port#’s to 2 and the Pin#’s to 14 and 16 respectively
(Config->Ports and Pins->Output Signals).
iv. Make sure the check box Di able Spindle Relay is unchecked and that the Clockwi e
Output # is 1 and the Counterclockwi e Output # is 2. Also, select the check box PWM
Control and set the PWM Ba e Freq. to 100 (Config->Ports and Pins->Spindle Setup).
b. REV and/or FWD do work
i. Set the spindle speed to the maximum pulley speed.
ii. Check the 0-10V on 0-10 terminal on the Apollo I Breakout Board with a voltmeter. You
should read 10V.
iii. Check your wiring.
