Control 3.8kW Servo motor with arduino

Hello guys,

I am having some trouble understanding this and getting it to work.

I have this servo motor:

https://www.aliexpress.com/item/3-8KW-CNC-AC-Servo-Motor-Driver-Kit-130ST-M15025-15Nm-2500rpm-220VAC-AASD-50A-220V/32870780686.html

Which comes with this drive (The drive we have is for the AASD-50A and the manual lunked below is for the AASD-30A, but they are basically the same):

I am a just graduated mechanical engineer, so my understanding of these kind of diagrams and communications is basically zero, I wanted to know if you guys could help, me figure out how should I connect the drive to my arduino, or if I'll need to use higher voltages to see how can i set some arduino-drived relays to control it. I dont need to control the position of my servomotor, I just need it to run in one direction for a certain amount of time and then invert the direction (Which I planned on doing with code and using two buttons).

Until now, after reading a bit of the techical manual, I can see the following and assume this:
On page 25 of the techical manual I see it says speed-torque control wiring diagram, which I guess is what I want to use just to control speed and torque as Im not interested in position. It says analog value goes into pin 25 (Do I send an analog value out from my arduino to set speed and torque? How should the signal be sent?) and +-10V to pin 13 (What does this voltage control? Can I send it directly through a relay and command my arduino to control the relay?)

I would really really appreciate some help understanding this,

Regards,

Adriano

p.s. English is not my first language so exuse me if I have something badly written

edit: All the powering done in CN1 and connections on CN3 are done, Im having trouble with the communication between the arduino and CN2 which is the I/O (I think thats what its called)

Are expecting us to believe a graduate mechanical engineer is unable to understand a pictorial diagram of how to wire up your device? Sorry, I cannot conceive of such a university mechanical engineering program.

Firstly most Arduinos don't produce analog out (analogWrite is PWM, not analog, usually).
Secondly industrial control systems use higher voltages than 5V, so some interfacing circuitry will
be needed to level shift to a +/-10V analog signal, for instance, or to read a 4--20mA current loop.

Servomotors are complex beasts with a multitude of modes and ways to control them, you have
to read the manual carefully and figure out the modes and inputs needed and how to configure
the controller for your needs.

If it has a serial port that might allow much easier control with serial commands?

[ and while testing assume the motor could do anything - disconnect any dangerous
or delicate load from the shaft!! Never operate it loose on the bench, it must be securely
mounted before power is applied, its quite capable of jumping and spinning itself
violently if accidentally triggered to high acceleration, these motors are way more
lively than a 4kW induction motor, for instance ]

Hi Mark,

Thanks for your reply, I'll try to make it work with that
