Reliance SS-90 MI402 identification help

Hi guys am a bit new here. I have a total of three Reliance motion control inc. ss-90 servo motors with model no:MI402.
One of the following motors has this listed on the tag.

Part no: EC690HTR014
Serial:H000510
Date code:3494
Stall torque: 6.9NM
MAX RPM: 4000rpm

There is a second label by reliance with the following info
Volts rms l-l: 240 /3 phase
HP: 3.3
Freq: 0-267
Amps rms const at stall: 9.0
Amps rms peak at stall: 20
Class: b

Two of these servos have ‘AccuTrue’ planetary gearheads by micron and the other has an electric cylinder by Indusrial devices corp out of novato, Ca.

I read that Reliance was bought out by Rockwell in late 94 (not long after these were made assuming date code is in the week/year standard) and saw motors like mine under the name electro craft. I couldnt find any specific data on mine. Does anyone know where to find a data sheet or if it got rebranded under a different name?

I got these for free because they were going to be thrown out otherwise but truth be told i have no idea what to do with them.
