Delta Electronics ASDA-AB manual Control Modes of Operation

Chapter 6 Control Modes of Operation

6.1Control Modes of Operation

The Delta ASDA-AB series 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.
	Internal Position Control	Pr	Position control for the servo motor is achieved via by 8
			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 steps of changing mode:

(1)Switching the servo drive to Servo Off status. Turning SON signal of Digit input to be off can complete this action.

(2)Using parameter P1-01. (Refer to chapter 7).

(3)After the setting is completed, cut the power off and restart the drive again.
