Chapter 1 Safety reminder
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 disposal. 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.
