5.2 Settings According to Host Controller
This section describes the procedure for connecting a Sigma II Series servo to a host con-
troller, including the procedure for setting related parameters.
5.2.1
Speed Reference
Input the speed reference using the input signal Speed Reference Input. Since this
signal has various uses, set the optimum reference input for the system created.
ð Input V-REF CN1-5
ð Input SG CN1-6
The above inputs are used for speed control (analog reference). (Pn000.1 = 0, 4, 7,
9, or A).
Always wire for normal speed control.
Refer to 7.1.7 Operation in Monitor Mode.
to the input voltage between V-REF and SG.
