1.1 Safety precautions
This section describes the important items that users must observe, such as product confirmation,
storage, transportation, installation, wiring, operation, inspection, and dispoal. Please follow the
steps required by this manual for trial operation.
✎After the power is turned off for more than 5 minutes and the power indicator is off, use a
multimeter to confirm that the voltage across the high-voltage capacitor has dropped to a safe
voltage, and then proceed with the disassembly and assembly of the drive, otherwise the residual
voltage may cause electric shock.
✎Please never touch the inside of the servo drive, otherwise it may cause electric shock.
✎Please insulate the connection part of the power terminal, otherwise it may cause electric
shock.
✎The grounding terminal of the servo drive must be grounded, otherwise it may cause electric
shock.
✎Please install the servo drive, servo motor, and external braking resistor on non-combustible
materials, otherwise it may cause a fire.
✎Be sure to connect an electromagnetic contactor and a non-fuse circuit breaker between the
power supply and the main circuit power supply of the servo drive. Otherwise, when the
equipment fails, it may cause fire because it cannot cut off the large current.
✎In the servo drive and servo motor, please do not mix with oil, grease and other flammable
foreign objects and screws, metal pieces and other conductive foreign objects, otherwise it may
cause a fire.
✎When the servo motor is connected to the machine, if an operation error occurs, it will not
only cause damage to the machine, but also sometimes cause personal safety accidents.
✎Do not damage or pull the cable forcefully, do not subject the cable to excessive force, or place
heavy objects underneath, otherwise electric shock may occur, causing the product to stop
operating or burn out.
✎Do not use the brake of the brake motor for normal braking, otherwise it may cause a
malfunction.
✎Except for the designated operator, please do not set up, disassemble and repair the
equipment, otherwise it may cause electric shock or injury.
✎Do not remove the cover, cables, connectors and optional accessories while the power is on,
otherwise it may cause electric shock.
✎Please install a stop device on the machine side to ensure safety.
✎Please take measures to ensure that your personal safety will not be endangered when
restarting, otherwise it may cause injury.
✎Do not modify this product, otherwise it may cause personal injury or mechanical damage.
