Confirmed with Teknic that I need the enable pin set up for this because it is disabled by default on startup. The software enable in the MSP software ignored hardware input when being used.

so then Outputs 1-4 (relays) and DB25 pins 1, 14, 16, 17 are always linked together? It seems to be this way, testing with a voltage tester. I wired up the enable and direction pins to the DB25 breakout, but the behavior is the opposite of what I'd expect: The Teknic motor is coming up enabled by de...

I need to send 5-24V signals to the Direction and Enable pins on a Teknic Clearpath motor. Looking at the wizard, the only thing I can find that looks right is VFDDirection and VFDEnable. I don't have a VFD but this seems like the functional equivalent. If I assign VFDEnable to an output in the wiza...

I have an email in to Teknic support, but I'm hoping someone here might know. I'm sure I'm missing something simple. Motor is CPM-MCPV-2311S-ELN and I'm controlling it from an Acorn. This is the spindle for my micro-lathe. Acorn outputs 0-10V, but the motor requires PWM input. I am running the 0-10V...

Ok, I got this working. It was, um, operator error. Basically, after bench testing I made up some DB9 connectors that will live underneath the slant bed for the lathe (it's a small Sherline lathe) so that I can easily remove it if I ever need to. I screwed up the wiring in one end of the DB9 connect...

Here's a report, if that helps.

Ahh. Thanks. Ok so I swapped the ALM +/- wires and now it's coming up with the correct lights on PLC diags and on the board. One problem solved. The home switches were already wired correctly, I shouldn't have included it in the list of things connected to +24V in OP, as that was incorrect. However,...

Green indicates that the circuit is closed. So if the driver's Alarm signal is set to normally closed, the indicator should be green until an alarm is triggered. So, why is the PLC diagnostic showing it as red, regardless of the setting for the alarm output on the driver (NC or NO)? Also, the behavi...

First, I'm running 5.08 still - I will be upgrading to the 5.1 beta soon, but I just want to get the basics working first. I tested the X and Z stepper motors for my lathe individually on the bench and they worked fine. That was about a month ago. I now have everything wired up in the machine, but I...

Yes. They say the only way to do it is with the voltage->PWM converter, either the one they sell or another. But others have wired it directly into the Acorn's DB25 connector, with success. Since I have a voltage to PWM converter board that meets Teknic's specs I'll probably cram that into the box a...
