Delta Electronics ASDA-AB manual Trial Run and Tuning Procedure, Inspection without Load

Chapter 5 Trial Run and Tuning Procedure

This chapter, which is divided into two parts, describes trial run for servo drive and motor. One part is to introduce the trial run without load, and the other part is to introduce trial run with load. Ensure to complete the trial run without load first before performing the trial run with load.

5.1Inspection without Load

In order to prevent accidents and avoid damaging the servo drive and mechanical system, the trial run should be performed under no load condition (no load connected, including disconnecting all couplings and belts). Do not run servo motor while it is connected to load or mechanical system because the unassembled parts on motor shaft may easily disassemble during running and it may damage mechanical system or even result in personnel injury. After removing the load or mechanical system from the servo motor, if the servo motor can runs normally following up the normal operation procedure (when trial run without load is completed), then the users can connect to the load and mechanical system to run the servo motor.

¾In order to prevent accidents, the initial trial run for servo motor should be conducted under no load conditions

(separate the motor from its couplings and belts).

¾Caution: Please perform trial run without load first and then perform trial run with load connected. After the servo motor is running normally and regularly without load, then run servo motor with load connected. Ensure to perform trial run in this order to prevent unnecessary danger.

After power in connected to AC servo drive, the charge LED will light and it indicates that AC servo drive is ready. Please check the followings before trial run:

Item		Content
	z	Inspect the servo drive and servo motor to insure they were not damaged.
	z	To avoid an electric shock, be sure to connect the ground terminal of servo drive to
		the ground terminal of control panel.
	z	Before making any connection, wait 10 minutes for capacitors to discharge after
		the power is disconnected, alternatively, use an appropriate discharge device to
		discharge.
Inspection before	z	Ensure that all wiring terminals are correctly insulated.
	z	Ensure that all wiring is correct or damage and or malfunction may result.
operation	z	Visually check to ensure that there are not any unused screws, metal strips, or any
(Control power is not
applied)		conductive or inflammable materials inside the drive.
	z	Never put inflammable objects on servo drive or close to the external regenerative
		resistor.
	z	Make sure control switch is OFF.
	z	If the electromagnetic brake is being used, ensure that it is correctly wired.
	z	If required, use an appropriate electrical filter to eliminate noise to the servo drive.
	z	Ensure that the external applied voltage to the drive is correct and matched to the
		controller.
