I think I have everything figured out for the spindle motor except I can't get the BoB relays to come on for forward and reverse signals to send out to the VFD. I am using the OB for step and direction to go to the BoB.
First of all, what ports and pins of the ESS actually send out these controls? I cannot find this anywhere. It seems like you need to know ports and pins to set it up or something.
I assume I need to set something up with the Spindle Fwd and Spindle Rev in the Output signals, but I am not sure what settings to make here.
The documentation for the ESS says this, but gives you no specifics on how to set it up:
"You may also assign the relays for Spindle On, Spindle Fwd and Spindle Rev as desired at this point."
You can also find this info, but it tells you nothing about setting them up other than when they come on:
Spindle related outputs.
Spindle Step or PWM: This will take the commanded spindle speed in RPM and convert it to an output signal with a duty cycle between 0% and 100%, which your spindle speed control module will convert into an analog voltage (typically 0v to 10 V DC). This analog voltages is used by your VFD to run your spindle at the commanded RPM.
Spindle Motor Dir: This output retains the current spindle direction even when the spindle stops. It only switches state when a direction change is ordered (which prevents spindle direction glitching).
Spindle On: This output is active when the spindle is active
Spindle Fwd: This output is active when the spindle is running forwards (CW)
Spindle Rev: This output is active when the spindle is running in reverse (CCW)
See attached pic for the settings I am talking about.
Do I need to set anything for Spindle - Unused? Why is this even there if it is unused?
Do I need to set anything for Spindle Motor Dir?
Do I need to use the Spindle On?
I assume my issue is that I do need to set something for Spindle Fwd and Spindle Rev, but I am not sure what. I assume to enable them and I guess pick ESS for Mach Mapping?? What do I pick for pin mappings?
