Chapter 5 Trial Run And Tuning Procedure; Inspection Without Load - Delta ASDA-A2 Series User Manual

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.

5.1 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:
1. Inspection before operation (Control power is not applied)
 Inspect the servo drive and servo motor to insure they were not damaged.
 Ensure that all wiring terminals are correctly insulated.
 Ensure that all wiring is correct or damage and or malfunction may result.
 Visually check to ensure that there are not any unused screws, metal strips, or any
conductive or inflammable materials inside the drive.
 Make sure control switch is OFF.
 Never put inflammable objects on servo drive or close to the external regenerative
resistor.
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.
