There's a throwback Thursday for you !
This is a "1336 Classic", before the 1336 Plus or the 1336 Plus II. It didn't have a modular "Human Interface Module", just a keypad that interfaced with the main control board.
Saving the parameters into a HIM module's flash memory to do a "HIM Copycat" was a feature of later drives.
Unless you can take off the Main Control Board and figure out what voltage to connect to J1, J6, or J7 plugs to power it up without the power structure of the drive, I think this is going to have to be a reverse-engineering project for you, examining the start/stop and reference logic, the load on the motor, and the operational needs of the driven load. I worked on the 1336 extensively but don't have notes about how to power up the main control board on a bench.
