Notes

It is important that the slave servo be capable of matching the master

servos response.

If:

And:

Then:

too great of a difference exists between the slave

and master servo’s response (i.e., greatly different

loads or very different motors)

the slave servo’s best possible response

(under load) is slower than the master

servo’s response

the slave servo never matches the response of the

master servo no matter how much the slave servo’s

gain is modified

slave servo’s response is faster (under

load) than the master servo’s response

the slave servo gain can be modified to slow down

the slave servos response and make it match the

master servo’s response

When designing your split axis, try to match servo motors and motor loads

as closely as possible. If this is not possible, make sure that the servo with

the slowest response (under normal operating load) is configured as the

master servo.

This parameter is a global parameter. The value set here applies to all axes.

For Dual Processing controls, this is a per process parameter. The value set

here applies to all of the axes assigned to that process.
