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
General Inspection	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.
Inspection before	„ Ensure that all wiring terminals are correctly insulated.
	„ 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

applied))	„ Ensure to reset some parameters when the servo drive is off (Please refer to
	Chapter 7). 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
