1. To prevent electric shock, please confirm the following:
Operate the power switches with dry hand to prevent an electric shock.
Before wiring or inspection, switch power off and wait for more than 10 minutes. Then,
confirm if the power indicator is off or the voltage is safe with voltage meter. Otherwise, you
may get an electric shock.
Connect the servo drive and motor to ground.
Do not attempt to wire the servo drive and motor until they have been installed. Otherwise,
you may get an electric shock.
The cables should not be damaged, stressed, loaded, or pinched. Otherwise, you may get
an electric shock.
2. To prevent fire, note the following:
Install the servo drive, motor and regenerative brake resistor in a clean and dry location
free from corrosive and inflammable gases or liquids. Otherwise a fire may be caused.
Don‟t try to operate the servo drive or motor which has become faulty. Otherwise, a large
current flow may cause a fire.
Do not connect a commercial power supply to the U, V, W terminals of drive. Otherwise a
fire may be caused and the servo drive will be damaged.
When an external regenerative brake resistor is used, check the specification
recommended. Otherwise, a regenerative brake transistor fault or the like may overheat
the regenerative brake resistor, causing a fire.
3. To prevent injury, note the following:
The proper voltage specified in this manual should be applied to each terminal, Otherwise,
a burst, damage, etc. may occur.
Ensure that polarity (＋,－) is correct. Otherwise, a burst, damage, etc. may occur.
Ensure that all screws, connectors and wire terminations are fixed on the power supply,
servo drive and motor to prevent from a burst, damage, or personal injury.
Don‟t touch either the drive heat sink or the motor during operation because they may
become hot and cause personnel burnt.
Don‟t approach or touch any rotating parts (e.g. shaft) to prevent from serious injury.
