4 Axis ethercat Lichuan stepper drive on LinuxCNC. This is the open-loop version without encoder feedback. Ethercat stepper drive model number: OL57E-4A Output 4x 5A Input: DC24V-50V V1.3.0

The manual lists one other servo drive model: CL57E-4A which is the closed loop version. Below is some information I got from the manual and labels. Being Chinese translated to English, hopefully I got the details straight.
