5.1 Control Selection5-35 Operation5.1 Control SelectionThe controls supported by the SGDV SERVOPACK are described below.Control can be selected with parameter Pn000.Control SelectionPn.000.1 Control Description ReferenceSectionn.0Speed Control(Analog voltagereference)[Factory setting]Controls servomotor speed by means of an analog voltage speedreference. Use in the following instances.• To control speed• For position control using the encoder pulse output from theSERVOPACK to form a position loop in the host controller.5.3 OperatingUsing SpeedControl withAnalog Volt-age Referencen.1 Position Control(Pulse train reference)Controls the position of the machine by means of a pulse trainposition reference.Controls the position with the number of input pulses, and con-trols the speed with the input pulse frequency. Use when posi-tioning is required.5.4 OperatingUsing Posi-tion Controlwith PulseTrain Refer-encen.2Torque Control(Analog voltage refer-ence)Controls the servomotor’s output torque by means of an analogvoltage torque reference. Use to output the required amount oftorque for operations such as pressing.5.5 OperatingUsing TorqueControl withAnalog Volt-age Referencen.3Speed Control(Internal set speedselection)Uses the three input signals /P-CON (/SPD-D), /P-CL (/SPD-A),and /N-CL (/SPD-B) to control the speed as set in advance in theSERVOPACK. Three operating speeds can be set in the SER-VOPACK.When selecting this control, an analog reference is not necessary.5.6 OperatingUsing SpeedControl withan Internal SetSpeedn.4xxxn.BCombinationThese are switching modes for using the four controls describedabove in combination. Select the control switching mode thatbest suits the application.5.7 Combina-tion of ControlModes
