1.5 Safety Instructions
Installation
DO NOT subject the product to water, corrosive or flammable gases, or combustibles.
DO NOT use the motor in a place subject to excessive vibration or shock.
Never connect the motor directly to the AC power supply.
DO NOT use cables soaked in water or oil.
DO NOT extrude or pull off the cable, or damage the cables as electrical shocks or damage may result
DO NOT block the heat dissipating holes. Prevent any metal filings from dropping into the drive during
installation.
DO NOT switch the power supply on and off repeatedly.
DO NOT touch the rotating shaft when the motor is running.
DO NOT strike the motor when during indtallation as the motor shaft or encoder may be damaged.
To prevent accidents, the initial trial run for the servo motor should be conducted under a no-load condition
(separate the motor from its couplings and belts).
Starting system operation without first matching the correct parameters may result in servo drive or motor
damage, or damage to the mechanical system.
DO NOT touch the drive heat sink, motor, or the regeneration resistor during operation as they may be very hot.
DO NOT hold the motor by the cable during transportation or installation.
Wiring
DO NOT connect any power supply to the U, V, or W terminals.
Install the encoder cable in a separate conduit from the motor power cable to avoid signal noise.
Use multi-stranded twisted-pair wires or multi-core shielded-pair wires for signal and encoder cables.
A
hazardous voltage charge may still remain in the drive even after the power has been removed - Do not touch
the terminals when the charge led is still lit.
Please observe the specified voltage(s).
Make sure both the drive and the motor connect to a class 3 ground.
Please ensure the grounding wires are securely connected before power up.
1.6 Guideline for Parts Replacement
1.6.1 Parts Replacement
Use the table below for a reference. Parts replacement cycle varies depending on the actual operating
conditions. Defective parts should be replaced or repaired when any error has occurred.
Prohibited
Disassembling for inspection and repair should be carried out
only by authorized dealers or service company.
Ambient conditions: 30°C (annual average), load factor of 80% or lower, operating time of
20 hours or less per day.
