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.
