between the clearances and the dimensions, the dimensions shall prevail.

Basic Inspection

After power in connected to the AC servo drive, the charge LED will be lit which indicates that the AC servo drive is ready.
Item Content
Periodically inspect the screws of the servo drive, motor shaft, terminal block and the connection to mechanical system.
Tighten screws as necessary as they may loosen due to vibration and varying temperatures.
Ensure that oil, water, metallic particles or any foreign objects do not fall inside the servo drive, motor, control panel or

ventilation slots and holes. As these will cause damage.
Ensure the correct installation and the control panel. It should be free from airborne dust, harmful gases or liquids.
Ensure that all wiring instructions and recommendations are followed; otherwise damage to the drive and or motor may result.
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.
Ensure that all wiring terminals are correctly insulated.
Inspection before
Ensure that all wiring is correct or damage and or malfunction may result.

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.
Ensure that all user-defined parameters are set correctly. Since the characteristics of various machines are different, in order

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.
