I am trying to build a Clough 42 ELS on my Eisen 1340GHE lathe, using a Teknic SDSK 23 servo motor.
I installed the motor to the lead screw and auto-tuned it and now it spins smoothly under power (meaning through the ClearPath MSP tuning software), but I cannot wire it properly to the ELS Board.
The Clearpath is set to 1800 pulses per rev (able to do 6400 but the ELS config upper limit is 2000, through a "sanity check"). I can enable/disable the servo motor by powering on/off the ELS board. The motor does not spin however in response to the encoder signal. The Omron encoder I am using does 2000 p/r so I set in the config for 8000. I can wiggle it by hand and it does "see" the rpms, but the servo does not turn:
Wiring
The Clearpath wiring from the manual is:
The ELS outputs from the Clough github wiki is:
Basically the Clearpath Enable (+), Dir (+) and Step (+) are all connected together and I feed them from the ELS PCB (+). The Step (-), Dir(-) and Enable (-) are all individually wired. I left the alarm outputs unconnected (is that a problem, perhaps?).
Can anyone suggest a wiring fix? Hopefully the Teknic support engineers or anyone else with experience will see this and comment. Grateful thanks to all.
