general Servo motor wiring question

[damunk]

Morning guys.

When you buy those cheap servo motors/drives from Korea they come with manual including wiring diagrams. Having hard time understanding them.

They show diagrams for switching input value, output value, wiring for pwm, pulse etc. Almost all of those diagrams have a resistor and diode setup.

Are they just showing those diagrams for reference. i,e are those the wiring WITHIN the servo drive?

Or are they showing you how YOU are suppose to wire the connections going into the CN1 connection pin/plug? If so there's abit more work to it than I thought.


regards.

The resistors and diodes are internal in the device.

Then why would they even want to show that in all most all asia servo manuals.
Is it incase the driver fails and you need to fix your self?

[Jim Dawson]

Many manuals show that, not just the Asian ones. It allows the user to understand the circuit to be able to design non-standard input circuits.
