Handmade rotary axis for 6400+s4. Question....

[an69]

Hello to all!

We want to retrofit our robot model (ABB IRB6400 M98 controller S4) external rotation axis.
Question: What engine should we use?

1) Servo motor with brake and encoder.
2) Relatively simple stepper motor.

Maybe you now what is the difference between the servo motor and a stepper motor or is it the same thing?

hi Andrey,

i'm in sort of a same situation, in fact ABB offers an external axis card + an additional SMB for the external axis, which is sort of the "official" route for integrating externals axis. if you want your rotary table to move simultaniously, that's probably the way to do. If you're fine with an indexed table, you can probably do it with programming the IO's...

Hi we can help you with an solution with both stepper or servo motor control, you can control the motor directly from robot IO, pulses the motor driver can control motors up to 1.5kW . See more at www.robotservice.se
The easiest is to use stepmotor, but be careful to use overpowered motor that is not stall. But the best solution is to use servo motor were you control the motor exactly and now the position, if something stuc you know it.
