8.2 Control Mode Selection8.2 Control Mode SelectionThe control modes supported by the SGDH SERVOPACK are described below.Parameter Control Mode ReferenceSectionPn000 n.0(Factorysetting)Speed Control (Analog voltage speed reference)Controls servomotor speed by means of an analog voltage speed reference. Usein the following instances.• To control speed• For position control using the encoder feedback division output from theSERVOPACK to form a position loop in the host controller.8.5n.1n.2n.3n.4•••n.BPosition Control (Pulse train position reference)Controls the position of the servomotor by means of a pulse train position reference.Controls the position with the number of input pulses, and controls the speedwith the input pulse frequency. Use when positioning is required.Torque Control (Analog voltage speed reference)Controls the servomotor’s output torque by means of an analog voltage torquereference. Use to output the required amount of torque for operations such aspressing.Speed Control (Contact input speed control)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 the SERVOPACK. Threeoperating speeds can be set in the SERVOPACK. (In this case, an analog referenceis not necessary.)These are switching modes for using the four control methods described abovein combination. Select the control method switching mode that best suits theapplication.8.68.78.88.1088-17
