Chevalier FCL-2480 Hickory Leadshine EL7 Build

[Lloyddunn]

Im new to this forum and to the centroid world. So here is what im working with.
Chevalier FCL-2480 Lathe with Hickory controller, panel mount hmi, jog panel, wireless mpg, yaskawa 616G5 spindle drive, Leadshine EL7 drives and 1800w servo motors.

Im finished with the installation of the hardware, cnc12 software and now working through the test phase for
el7 drives and motors. Where im at now is on the TB323 page 10 where it explains how to clear err153. I have followed the instructions for resetting parameter 0.15 to 9 and as soon as i do it returns to 1 without clearing the err. i have also tried to save the parameters and cycle power with no change. My question is what could i be doing wrong as err153 is the only fault i have and the readout of x and z position shows on the cnc12 and will change when i manually turn the motor shafts. thanks for any advice in advance

Here is the google photos link with the same pictures as already pictured.

Hello and welcome to the forums! That looks like a well done cabinet layout.

Parameter 0.15 will automatically change back to a value of 1 after setting it to 9.

I have a guess as to why Er153 is not clearing. Do you recall if you installed any batteries in the boxes on the encoder cables? If not, could you please pop one open and see if there is a battery inside?

[Lloyddunn]

Yes batteries are installed in the cables. This is a new installation so I honestly didn’t check the voltage on the batteries I can check voltage to make sure they are up to par.

[centroid467]

Alright, thank you for checking. If you do look at the voltage, you should see around 3.6V across batteries that are new or have plenty of life left.


Assuming the batteries are good, then I think we are at the point of checking things that otherwise would be assumed good. I can't think of many other reasons for this to happen without suspecting something is incorrect.

A short list of things you can check is as follows:

* Encoder is not absolute. Since we sold you the motors and drives, it is likely that you have the correct type. ELM2 motors all come with the 23 bit optical multiturn absolute encoder. Not likely culprit here. You can verify you have the right model numbers - your motors should be ELM2H-1800LD130F-H.

* Battery voltage not reaching encoder. Disconnect the encoder cable from the motor and drive then measure across pins 6 and 7 on the motor connector. You should see roughly the same voltage you saw across the battery. The voltmeter should read positive voltage with the red lead on pin 6 and the black on pin 7.

* Connectors may be dirty or have conductive debris. Not very likely considering new installation but anything can happen. On the motor connectors, you can blast it out with clean compressed air then electrical contact cleaner. Drive connectors, I would blow out with breath and then use contact cleaner.

Looks like you were right one of the batteries was not properly connected! Thanks for the help!

[centroid467]

Glad I could help!

Please let us know how the rest of the build goes!

I have a question regarding the spindle gear selection logic for my lathe with a hickory controller. I have read about using macros for this but there is also a section I’ve read about using the existing plc logic that is standard with my hickory for gear shifting along with changes in macros. Could you explain the process of setting this up for a spindle that has an encoder directly coupled with the chuck? That being said I can shift between low-med-hi and I don’t have gear ratios to compensate for in the parameters just the fact that I have 3 ranges of speed to automatically switch between in a program. I have 3 outputs for air sol to shift with 3 input switches to show what gear it’s in. Any help would be appreciated as I’m new to centroid plc language.

[centroid467]

I'm not positive this requires PLC changes beyond assigning inputs and outputs to set up. You'll also need to set some parameters.

So, you have switches that can tell the Hickory which range the spindle is in and you have solenoids to control the shifting.

It sounds like you should figure out the gear ratios. Do you happen to know the min and max speeds in each range?

Are you using the Wizard for setup or directly modifying the PLC?

[Lloyddunn]

As far as min and max settings I’m using a vfd for the spindle so I can run each gear down to 0 and the max for each gear is 398,1240,3680RPM. My encoder is directly coupled to the chuck so I’m not sure if there is a need for gear ratios unless it’s used to select when to shift gears. My wizard came standard with inputs for my low,med,and high inputs but has no selection for outputs to assign to my valves. Let me know if you need any additional info.
