1.5Control Modes of Servo Drive

The Delta Servo can be programmed to provide six single and five dual modes of operation.

Their operation and description is listed in the following table.

	Mode	Code	Description
	External Position Control	Pt	Position control for the servo motor is achieved via an
			external pulse command.
			Position control for the servo motor is achieved via by 8
	Internal Position Control	Pr	commands stored within the servo controller. Execution of
			the 8 positions is via Digital Input (DI) signals.
			Speed control for the servo motor can be achieved via
			parameters set within the controller or from an external
	Speed Control	S	analog -10 ~ +10 VDC command. Control of the internal
			speed parameters is via the Digital Inputs (DI). (A maximum
			of three speeds can be stored internally).
Single			Speed control for the servo motor is only achieved via
Mode	Internal Speed Control	Sz	parameters set within the controller. Control of the internal
			speed parameters is via the Digital Inputs (DI). (A maximum
			of three speeds can be stored internally).
			Torque control for the servo motor can be achieved via
			parameters set within the controller or from an external
	Torque Control	T	analog -10 ~ +10 VDC command. Control of the internal
			torque parameters is via the Digital Inputs (DI). (A
			maximum of three torque levels can be stored internally).
		Tz	Torque control for the servo motor is only achieved via
	Internal Torque Control		parameters set within the controller. Control of the internal
			torque parameters is via the Digital Inputs (DI). (A
			maximum of three torque levels can be stored internally).
		Pt-S	Either Pt or S control mode can be selected via the Digital
			Inputs (DI)
		Pt-T	Either Pt or T control mode can be selected via the Digital
			Inputs (DI)
	Dual Mode	Pr-S	Either Pr or S control mode can be selected via the Digital
			Inputs (DI)
		Pr-T	Either Pr or T control mode can be selected via the Digital
			Inputs (DI)
		S-T	Either S or T control mode can be selected via the Digital
			Inputs (DI)

The above control modes can be accessed and changed via by parameter P1-01. If the control mode is changed, switch the drive off and on after the new control mode has been entered. The new control mode will only be valid after drive off/on action. Please see safety precautions on page iii (switching drive off/on multiple times).
