4.2 Settings According to Host Controller
This section describes the procedure for connecting a Σ - ΙΙ Series Servo to a host controller,
including the procedure for setting related parameters.
4.2.1 Speed Reference
Input the speed reference using the following input signal speed reference input. Since this
signal has various uses, set the optimum reference input for the system created.
The above inputs are used for speed control (analog reference). (Pn000.1 = 0, 4, 7, 9, or A)
Always wire for normal speed control.
The motor speed is controlled in proportion to the input voltage between V-REF and SG.
