Additional Manual
General
This manual described the method of parameter setting when the rotary scale which
has no rotary data (the number of rotation) is used, such as Heidenhain rotary scale
RCN723 or Futaba rotary scale FRR902L3DB.
We have improved our software, and removed the problems when a rotary scale
without rotary data was used, by some parameters settings.
And it is required to set some servo parameters in order to use Heidenhain encoder
RCN223, 723 and 220. In the case of using such a scale, please set servo
parameters with referring to “Method of using Heidenhain rotary scale RCN223, 723
and 220”.
