Nice video. My Clearpath servo is supposed to be delivered tomorrow and can't wait to get it going.
Where did you purchase your Clearpath servo?
Great video, very helpful. Can you have the encoder A & B outputs from the motor to be connected to a CNC controller to make it fully closed loop. Out clients love MASSO + ClearPath combination and we are adding an option to make MASSO fully closed loop and want to integrate ClearPath's to this setup.
Hi Masso CNC Controllers,
At this time, it's not possible to stream an output signal from ClearPath's encoder. Teknic made the active decision to design ClearPath this way for both cost and robustness reasons.
Depending on the application objectives, ClearPath can often accomplish the user's goals through a different method. For applications where streaming encoder data is necessary, mounting a third party external encoder may be a suitable option.
Please feel free to contact support@teknic.com with any additional questions.
Best regards,
Bridgette G.
I realize it's kinda randomly asking but do anybody know of a good site to stream new series online?

@Hassan Maxton Thank you, I went there and it seems to work :) I really appreciate it!!
@Rene Javion glad I could help xD
I'm simple terms, If I have to replace my existing 3 hp induction motor with yours servo, what HP would u recommend keeping all other rpms, feeds etc same/constant ?
Hi Sunil,
Teknic's AC Input line of ClearPath might be a good fit for replacing
your induction motor, and may even be a drop-in replacement. There are a
few key things needed to help with a retrofit:
(1) What speed is the AC Induction motor rated at? For example,
1800 and 3600 RPM are common speeds. (since horsepower is the product of
torque and speed, a 3 HP motor rated at 1800 RPM has twice the torque
compared to a 3 HP motor rated at 3600 RPM).
(2) What control is needed? If you just need velocity control (no
positioning) via digital I/O (such as frequency or PWM), the MCVC series of
ClearPath may be a good fit; if you need to do rigid tapping or other
positioning with the axis, the SD series of ClearPath with Step and
Direction or Quadrature A/B will probably be the best fit.
(3) What frame size is needed? We have NEMA 56, 143/145, and metric D100.
I just sent you an email earlier today to follow up to your contact
Request you left on our web site. Please send me an email when you have a moment and we would be
happy to help select an appropriate servo. Thanks!

I want to use this as an outboard engine is there a way to hook up knob to control speed like an outboard control have.
Hi Richard - It is possible to use a quadrature output "knob" to control motor speed with a ClearPath. This operational mode is called "Manual Velocity Control" and is discussed in the ClearPath User Manual as well as in a video on Teknic's website that can be found here: th-cam.com/video/tR_LrL7UjdA/w-d-xo.htmlrel=0&iv_load_policy=3
That said, I would advise against trying to use a ClearPath motor in place of an outboard motor engine; the two are in different power classes and therefore not interchangeable.
To elaborate, even when run at their optimal voltage (75 VDC), the ClearPath motors shown in this video are fractional horsepower motors (
Can I use a TB6600 Stepper driver to use the SD and SK series in my CNC Machine?^^
Hi dunichtich100,
The TB6600 is a stepper motor driver drive used to drive two-phase stepper motors and is not compatible with ClearPath motors. ClearPath motors are integrated servo motors that have their own servo drive built into the motor housing. This means that you do not need a separate motor driver. However, you will need a controller that sends 5-24VDC step and direction signals to the ClearPath motors as your command signals.
More information can be found in the ClearPath User Manual for the SD series motors.

Teknic Inc Thank you verry much for this quick answer Tom :)
What kind of loopback sensor have been used? Optical encoder or magnetic encoder?
Hi Vadim,
All ClearPath integrated servos use an optical incremental rotary encoder.
The AC powered ClearPath (NEMA 56 and 143/145) use a native 64,000 counts per revolution encoder and the DC powered ClearPath (NEMA 23 and 34) use a native 12,800 counts per revolution encoder. This internal resolution is used by the servo drive’s algorithms and helps to provide high precision and repeatable performance.
Keep in mind that the internal resolution is different from the achievable positioning resolution (Regular or Enhanced) that you choose when you select a ClearPath model. For more information on positioning resolution, check out Appendix G in the ClearPath manual. The positioning resolution is also shown on our website in the specifications table for each motor part number. Look for the spec called “Achievable Resolution”.

The 300 nanometer of optical grating is amazing. Reality cool. I'm not professional and does not work in this like industry. I'm hobbyist and for me it is amazing.
Good video, are these motors suitable for Bridgeport vertical mill?Price list.
Hi gyhembree,
I'm an engineer with Teknic who was forwarded your recent contact request.
We recommend the ClearPath SD (Step and Direction) series for all types of CNC applications, including Bridgeport mills. Just be sure that your CNC controller can output step/direction - this will ensure compatibility with the “SDSK and SDHP” ClearPath series. You can find a complete list of SD ClearPath motors along with their performance characteristics and pricing at:
www.teknic.com/products/clearpath-brushless-dc-servo-motors/clearpath-sd/all-sd-models/
More background information on the SD (step/direction) ClearPath series can be found here:

For a cnc manufacturer do they have to autotune for every single machine even though the machines are identical.
Hi MySchizoBuddy
ClearPath motors are designed so once the first machine is properly tuned, subsequent builds of the same design will not require individual tuning. This means that the 2nd, 10th, and 10,000th machine of the same model use the tuning files created for the first machine. (Of course, this assumes the machine's mechanics such as screw pitch, gear reduction, etc. don't significantly change.)
Typical machine-to-machine variation caused by normal part tolerances and assembly practices is easily compensated for by ClearPath's robust PIV servo algorithms and Inertia Matching Technology.

Can you explain what the CP servo model numbers and letters mean? I have looked but haven't found anything on the subject.
Hi Halfstep67,
I’m an applications engineer with Teknic and I am happy to help. Thank you for bringing this to our attention, we will try to make the part number scheme more prominent on the website in the future.
It’s probably easier for me to try and direct you to where you can find the part number description on the website because the definition depends on a number of factors (e.g. frame size, the ClearPath series you’re using, etc.).
You can find a broad overview that covers all ClearPath families and sizes by following the link below. Once there, click on the “?” icon in the “part number” heading (it is in the upper left of the model filter): www.teknic.com/products/clearpath-brushless-dc-servo-motors/all-clearpath-models/#ppsShowPopUp_100.
When you know which motor series you’re interested in, you can find a more-detailed breakdown of the part number key for that specific ClearPath series in the corresponding ClearPath User Manual (take a look in the “Part Number Key” appendix). These manuals can be downloaded from Teknic’s website here: www.teknic.com/downloads/.
Unfortunately TH-cam doesn’t allow for the posting of images, but I’d be happy to send you this information directly. So, if these links don’t help, or if you have any questions about a specific part number, please feel free to contact us directly at support@teknic.com.
Thank you,

How to clear the De-assert the HW enable input to proceed, while clearpath tuning
Hi @user- vw7ux5dh9t,
It sounds like your motor is enabled by external hardware connected to the motor’s 8-pin Molex Mini-Fit Jr. controller connector. To run the auto-tuner, you first need to 'disable' the motor (i.e., turn off power to the motor's enable input circuit).
For almost all applications, it is important to be able to disable the motor using your external hardware (e.g., if you have a Step & Direction indexer/controller, you should have programmatic control over the motor's enable input). But if you don't have control over the enable input for some reason, you could remove the 8-pin controller cable from your motor to de-energize that enable input. Once the motor is disabled, you will be able to run the auto-tuner.
I hope this information helps. If you have any other questions related to Teknic's products, please feel free to reach out to us directly by phone (585-784-7454) or use our “Contact Us” form at teknic.com/contact/.

PM 833TV Looking for Z axis Servo or Stepper any turn key set up ?
Hi Dew411 - ClearPath servos may be a good fit for your mill Z-axis if you’re looking for a servo motor, drive and encoder solution all-in-one. CNC retrofits and upgrades are commonly done using ClearPath-SD because this series of ClearPath is designed to accept Step & Direction or Quadrature A/B signals from the machine controller. This is usually the closest option for a “turn key” servo upgrade in CNC applications, assuming you have one of these types of signals (5-24VDC Step & Direction or Quadrature) available for the Z-axis control.
You can use the Motor Selection Guide on Teknic’s website to help size the motor based on the axis torque and speed requirements:
teknic.com/products/clearpath-brushless-dc-servo-motors/clearpath-motor-selection-guide/
I hope this helps! Please feel free to give us a call (585-784-7454) or leave us a message at www.teknic.com/contact/ if you have any additional questions.

Hi Teknic Inc.
Is it possible to run 2 programs all at once? For example: if i click green button, the servo direction will be CW, but the speed is 0 until i turn the potentiometer to increase the speed. And when i click red button, the servo direction will be CCW directly.
Is it possible to do that in clearpath servo? What parameters should i set? Thank you..
Hi Amandito,
There are several different operational modes available in the MC and SD series of ClearPath motors which will likely work in your application but we would need more information to make a specific recommendation. If you haven't already, you can find detailed videos for each operating mode on our website/youtube channel th-cam.com/channels/4Q91tGO80QMSHyy1SoHrtg.html, but if you have any additional questions about which mode could work for you please give us a call and one of our trained applications engineers can assist you.

show us how to wire our own controls
Hi MySchizo Buddy
,
This video overviews getting started with a ClearPath servo from wiring DC power (this video features a DC input model), to familiarizing yourself with the Motor Setup Program (MSP) software, and spinning the motor with no load.
After that, one of the next steps is to wire your own controls. To help with this, we've included wiring diagrams and many other resources in the ClearPath MC/SD User Manual (which can be found on our support page: www.teknic.com/clearpath-model-support/ ). You'll just need to find out what type of inputs/outputs your specific controller has.
If you have questions about wiring a specific controller to a ClearPath, please feel free to contact us directly at support@teknic.com.

Hi my name is Lanre Akindele, I will like to understand more about this position about this products, I would like this motor to move from 0 to 90 degrees negative back to 0 degrees and again from 0 degrees to 90 degrees + and back to 0 degrees. Can it work that way round please let me know I will get one for try if it works I will order for more
Thanks
Lanre Akindele
Hi Lanre,
Yes - both the ClearPath-MC and the ClearPath-SD motors that we discuss in this video are capable of moving back and forth between three (or more) positions (-90°, 0°, +90°). The ClearPath-MC and ClearPath-SD motors are controlled in different ways, so you’ll want to choose the option that makes the most sense for your application. Here’s a high-level overview of the ClearPath-MC and ClearPath-SD motors:
The ClearPath-MC motors are available in two different models. The MCVC model is typically used in speed or velocity control applications, whereas the MCPV model is typically used in positioning applications (like the one you described). Both MCVC and MCPV models are controlled through digital I/O (e.g. electrical switches, knobs, or even PLC/microcontroller outputs). If you’re interested in learning more about the ClearPath-MC series, I encourage you to take a look at the ClearPath-MC information and videos found here: teknic.com/products/clearpath-brushless-dc-servo-motors/clearpath-mc/
The ClearPath-SD motors take in electrical Step and Direction or Quadrature A/B signals, and the motors interpret those signals as position and velocity commands. Those signals are commonly available from PLCs, standalone motion indexers, and microcontrollers like ClearCore (teknic.com/products/io-motion-controller/). If you’re interested in learning more about the ClearPath-SD series, please take a look at the ClearPath-SD information and videos found here: teknic.com/products/clearpath-brushless-dc-servo-motors/clearpath-sd-servo/.

Did i hear him right in the beging of the video he said 75volts would give you 3 times as much as 24volts well no shit Sherlock
Hi Jeff,
this point is certainly intuitive (some might even say, "It's elementary my dear Watson.") yet because of it's simplicity, we've found it's often easy to overlook. There are some less intuitive caveats here as well, which are important to mention. That's why in the video we carefully chose to begin this statement with, "In many motors..." because oddly enough increasing the power supply voltage 3x does not mean every motor's power will always increase 3x. The outcome could range from no increase in motor power whatsoever to a more than 3x increase in motor power. If you're interested I've gone into some more detail about this below.
Let's take the first example, where increasing the power supply voltage 3x does not increase the motor power proportionally. This can occur when the motor is already operating near its max rated operating speed at 24VDC. Now, when we increase the voltage, we get a less than proportional increase in speed. If our speed doesn't increase, then neither does our mechanical power. (For anyone following along, keep in mind that mechanical power = torque * speed.)
Note that increasing the voltage can still be helpful in these situations. First, it may allow you to move to a smaller, less expensive motor with a more optimized stator winding that can take advantage of the increased voltage and second, it increases engineering margin.
The second example, where the motor can actually output more than 3x the power at 75VDC is a bit more complex. I won't go into a ton of technical detail here but the important thing to know is that the motor essentially acts like a resistor in the circuit and therefore has an associated voltage drop. This voltage drop makes up a greater percentage of 24VDC than it does 75VDC. Depending on the winding configuration of each motor, and its subsequent resistance, it's not uncommon for motors to have more than 3x the mechanical power at 75VDC.
Take the CPM-MCPV-3441S-ELN motor for example. This motor has 6.7x the continuous power, and 9.4x the peak power at 75VDC. This can be calculated from comparing their two torque-speed curves: www.teknic.com/compare-clearpath-models/?one=147&two=147&loaded=1
Hopefully we can elaborate on this in a future video. In the meantime thanks for watching!
