Preface and Precautions
Please pay attention to all the information about safety in this book.
If you do not follow the warnings, you may cause death or serious injury, so please pay attention. The company will not be responsible for any damage
or equipment damage caused by your company or your company's customers who fail to comply with the contents of this book.
In order to prevent electric shock
Do not perform inspection or wiring work while the power is on. Be sure to turn off the power to all machines before wiring or repair work. Even if the
power is turned off, there is residual voltage in the capacitor inside the drive. To prevent electric shock, at least wait for the time specified on the
warning label on the front panel of the unit. After the indicators are all off, remove the front cover and terminal cover, measure the input supply voltage
and the main circuit DC voltage, and confirm that it is below the safe voltage.
For mechanical safety
After the wiring operation and parameter setting are completed, be sure to carry out trial operation to confirm that the machine can operate safely,
otherwise it may cause injury or equipment damage.
Be sure to confirm the setting value of the parameters for the virtual input/output function before the drive is tested.
The virtual input/output function is to make the virtual connection of the input and output terminals inside the drive. Therefore, even if there is no wiring
on the input and output terminals, the operation of the drive may be different from the factory setting. If it is neglected, the accidental operation of the
drive may cause personal accidents.
Before turning on the drive power supply, make sure there are no people around the drive, motor, and machine. Also, check that the cover, coupling,
shaft key, and machine of the drive are properly protected.
Some systems may suddenly move the machine when the main circuit is energized, posing a risk of death or serious injury.
The drive's external terminal control is used. The function of the drive's input and output terminals will be different from the factory settings. Therefore,
the operation of the drive may be different from the factory settings described in the instruction manual. Before the drive is tested, please use the
external terminal control to confirm the input and output signals and internal sequence of the drive.
It is forbidden to modify the drive.
If your company or your company's customers have modified the product, the company will not be responsible.
Non-electrical construction professionals should not perform wiring, installation, maintenance, inspection, component replacement or repair work.
Do not remove the cover of the drive or touch the printed circuit board while the power is on.
Do not mistake the voltage of the main circuit power supply. Before powering on, please confirm whether the rated voltage of the drive is consistent
with the power supply voltage.
Please follow the local standards and set the bypass protection circuit. Improper wiring may result in fire or personal accident.
NOTE
In order to prevent injuries
Do not carry the drive with the front cover or terminal cover of the drive. In addition, please confirm that the screws are properly tightened before
handling.
