Sigma II User’s Manual Chapter 5: Parameter Settings and Functions5 - 145.2 Settings According to Host ControllerThis section describes the procedure for connecting a Sigma II Series servo to a hostcontroller, including the procedure for setting related parameters.5.2.1 Speed ReferenceInput the speed reference using the input signal Speed Reference Input. Since thissignal 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.Refer to 7.1.7 Operation in Monitor Mode. The motor speed is controlled in propor-tion to the input voltage between V-REF and SG. Setting ExamplesPn300 = 600: This setting means that 6V is equivalent to the rated motor speed.Parameter Pn300 can be used to change the voltage input range.Input V-REF CN1-5 Speed Reference Input Speed ControlInput SG CN1-6 Signal Ground Speed ControlSpeed ReferenceInput Rotation Direction Motor Speed SGMAHServomotor+6V Forward rotation Rated motor speed 3000rpm+1V Forward rotation (1/6) rated motor speed 500rpm-3V Reverse rotation (1/2) rated motor speed 1500rpmTorquereferenceSpeedreferenceCN1-9CN1-10CN1-5CN1-6SGV-REFSGT-REFServo amplifierTorque reference input(analog voltage input)Speed reference input(analog voltage input)P represents twisted pair wires.PPInput voltage (V)-4-8-124 8 12Factory settingRated motor speedRated motor speedThe slope is set in Pn300.
