Item Content
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 the ground
terminal of control panel.
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 Ensure that all wiring terminals are correctly insulated.
operation Ensure that all wiring is correct or damage and or malfunction may result.
(Control power is Visually check to ensure that there are not any unused screws, metal strips, or any conductive or
not applied) inflammable materials inside the drive.
Never put inflammable objects on servo drive or close to the external regenerative resistor.
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 controller.
Ensure that the cables are not damaged, stressed excessively or loaded heavily. When the motor
is running, pay close attention on the connection of the cables and notice that if they are damaged,
frayed or over extended.
Check for abnormal vibrations and sounds during operation. If the servo motor is vibrating or there
are unusual noises while the motor is running, please contact the dealer or manufacturer for
assistance.
Inspection during
Ensure that all user-defined parameters are set correctly. Since the characteristics of various
operation machines are different, in order to avoid accident or cause damage, do not adjust the parameter
(Control power is abnormally and ensure the parameter setting is not an excessive value.
applied) Ensure to reset some parameters when the servo drive is off (Please refer to Chapter 8 of the user
manual). Otherwise, it may result in malfunction.
If there is no contact sound or there be any unusual noises when the relay of the servo drive is
operating, please contact your distributor for assistance or contact with Delta.
Check for abnormal conditions of the power indicators and LED display. If there is any abnormal
condition of the power indicators and LED display, please contact your distributor for assistance or
contact with Delta.
