Chapter 5 Trial Run And Tuning Procedure; Inspection Without Load - Delta Electronics ASDA-AB Series User Manual

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.
5.1

Inspection 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.
 In 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).
 Caution: 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
 Inspect the servo drive and servo motor to insure they were not damaged.
 To avoid an electric shock, be sure to connect the ground terminal of servo drive to

applied)
 Never put inflammable objects on servo drive or close to the external regenerative
 Make sure control switch is OFF.
 If the electromagnetic brake is being used, ensure that it is correctly wired.
 If required, use an appropriate electrical filter to eliminate noise to the servo drive.
 Ensure that the external applied voltage to the drive is correct and matched to the
