Two DC servo motors have INCREMENTAL ENCODERs on single axis. I have 5 axis masso controller.When i home synchronize them together ,will they make reference 0 point even if they home separately?Please help to understand?
Does anyone can help if i can use incremental DC servo motor to run on Masso?I have servo drives which can read servo with incremental encoder.But what about masso controller?Will i able to get zero position with them by homing to point?
I have bought masso controller but no help at all?Most info are with hybrid stepper motors or few info with ac servo system but not dc servo ?????Help?
MASSO provides step and direction signals to the motor drives no matter whether you use Stepper motors, AC or DC servos. Once the step and direction signals are sent to the driver it it up to the driver to deal with it. MASSO does not read the encoders or monitor position as that is the drivers job. In the case of servo or hybrid drive you can connect an alarm or a MASSO input to stop the machine in case of positional error of other alarm condition.
Homing is done using external homing sensors and not motor encoders.
This video will help explain how to set up homing
Thank you for reply understand it.I just figure out what to dne more thing,can i use one limit switch on my gantry and have mark points(plates) on the front and rear path axis.Will masso controller figure out,or should i add two limit switches on the front and rear axis?Picture attached.
My machine already have one limit switch which i have in the picture.
How difficult to configure masso?Appreciate for any opinion.
Hello and thank you for all info.I have converted Tekcel CNC machine to new Masso controller.Have spend 3 days and have achieved this ,very happy.The Masso can run any servo motor AC or DC.I have left all original dc servo motors,added new drivers and masso controller.The only concern i have how to wire correct the ABB VFD inverter.It was wired previously to same spindle,just need to run it on masso.I want tofind which terminal i have to use 0-10V from inverter to masso.PLease help i have inverter pin info.
I want to find out whic terminal is ACM and VI to use connect masso.Thank you.
My tekcel Machine already had wired vfd and worked perfect with other controller.I can run manual vfd at the moment.It is working correct.
Now the issue is that i have converted full electronic brains to Masso. All parameters were programmed already on vfd brain.
I just need to connect correct pins to masso ,can you confirm if i have connected correct?
The Abb has loc mode and memory mode.Once you add to local mode then i able to run spindle manually which i do at the moment.It works fine.To run automatically i need to switch to memory mode which mean masso has to control it.
But when i switch to memory mode the masso do not recognise abb. So i guess some wirring connections are missing or i am doing something wrong.
Can you draw diagram how to connect to masso please,AS i do not understand .
I have checked memory loc and mem mode and 9902 was entered 1 not 3.
There are many connection methods for VFD's and what works for one controller may not work for another.
Many VFD's allow multiple configurations to allow compatibility with many different controllers.
MASSO does not work correctly with a VFD that had an Run /stop input and a forward / reverse input as you currently have it set.
Please see the video in the documentation on connecting a VFD as it explains the requirements and takes you through the connection process step by step. https://docs.masso.com.au/wiring-and-setup/setup-and-calibration/spindle-vfd-examples
MASSO requires you to configure your VFD to have a FWD on/off input and a REV on/off input which according to the manual you provided is possible on your VFD.
This is why the first step in connecting any VFD to any CNC controller is to set the VFD to match the controller requirements and test that they work manually.
Only after you have tested and confirmed it is correct then do you start connecting the VFD.
With your current VFD configuration the best you can have is the spindle run in the forward direction only with speed control.
I have drawn a connection diagram based on a correctly configured VFD.
It would be prudent for you to go through the video in the documentation following the steps which will take you through the connection process in a methodical manner testing as you go.
It will also allow you to check the connection diagram I have provided is correct.
Thank you.I have done same as you said.When i choose 9902 parameter to 3 i have vfd fault (1009)when i press masso spindle run.
Then i switch 9902 to default mode 1 The masso and spindle runs,no fault.
I have programmed abb all parameters with 24000rpm 380V 10aA 400HZ,but when i start spindle through masso max 24000rpm my spindle spins only 50HZ.Also my spindle motor had a stop break,now it is not working.When I stop spindle still spinning free till i stop it manually.Can not find why my abb runing only 50HZ when masso shows 24000rpm (400Hz).
regarding your Tekcel, what made you want to change its controller, if you don't mind me asking?
And did you retain the Tekcel TT10 drive cards to use with the Masso?
Our router is an ancient Esab, that was retrofitted with Texcel k-series controller and drives 20 years ago.
I've repaird and nurtured it aloing, and often thought about changing controllers (when it plays up) but I usually get it going again.
I'd be interested in any Tekcel electronic parts you have that you don't need any more - just as a sort-of insurance for mine!
PS Like you, we manually get the spindle (a 3hp Perske) up to speed, I don't let the PC or controller do it.
