question when using chinese servo drives with original motors

Hi guys

I have a chinese servo drive and also have a bunch of yasakawa servo drives which I am trying to get working with my original heidenhain servos. I have a incremental encoder which is supposed to be compatible from the chinese servo drive company, installed on my motor and I want to know if I need to align the encoder to the motor poles to get good commutation. I am a little out of my depth and hoping that someone here can shed some light on my problem.

regards

Andrew

Yes they will need to be aligned. But the procedure for doing so, varies from drive to drive, and manufacturer to manufacturer. Plus I doubt the procedure will be covered in the pathetic documentation that comes with most Chinese products.

Also many servo drives are only ever intended to be used with the motors they were designed for, and don't offer any means for accommodating other commutation schemes.

Hi
i try the same with Chinese driver and encoder and fanuc motors
the problem in my case was different voltage
the fanuc work with 155 volt the Chinese with 220 volt
as for the aligning procedure it is easy
you have to set some parameters and then it is automatic procedure
hope this is helpful

Its good to hear someone else has tried the chinese servo drives.

have you actually managed to get some working with your motors?

I also have a cnc lathe with a fanuc controller so might go down the same path after the mill retrofit.

I think we should compare notes and might be able to help each other out.

In my case the fanuc motors are working with 155 volts and the Chinese
with 220 volts so there are incompatible
There 2 other options one with Mesa bldc and another one with Argon driver
The cost of Argon 4 pieces for my cnc it was around 3000 euros higher than
new Chinese servo set
So i replace the fanuc motors also with Chinese ones

I'm successfully running six China AC servo motors (110ST-M06030 1.8 kW and 80ST-M02430 0.75 kW models) using the China AASD drives typically sold with those motors. The documentation is full of mystery, but the products are well made and perform as promised. You can configure them to run in position mode with step/dir inputs, or speed mode with 0-10V analog input. There's also a 0-10V torque mode that I haven't tried. The trick to interfacing them is that they work off 12-24VDC PLC levels, not TTL, so you need a level shifter to work with TTL parallel port or other signal sources.

The AASD is configurable to a range of motor currents, so they might work with some non-China 3-phase AC servo motors.
