For Safe Operations
1. Prevention of electric shocks
1. Prevention of electric shocks
DANGER
Never open the front case or terminal covers of the servo amplifier while the power is ON or the
unit is running, as this may lead to electric shocks.
Never run the unit with the front case or terminal cover of the servo amplifier removed. The high
voltage terminal and charged sections will be exposed and may lead to electric shocks.
Never open the front case or terminal cover of the servo amplifier at times other than wiring work
or periodic inspections even if the power is OFF. The insides of the position board and servo
amplifier are charged and may lead to electric shocks.
amplifier are charged and may lead to electric shocks.
Completely turn off the externally supplied power used in the system before mounting or
removing the position board, performing wiring work, or inspections. Failing to do so may lead to
electric shocks.
removing the position board, performing wiring work, or inspections. Failing to do so may lead to
electric shocks.
When performing wiring work or inspections, turn the power OFF, wait at least ten minutes, and
then check the voltage with a tester, etc. Failing to do so may lead to electric shocks.
Be sure to ground the controller incorporating the position board, servo amplifier and servo
motor. (Ground resistance : 100 or less) Do not ground commonly with other devices.
The wiring work and inspections must be done by a qualified technician.
Wire the units after installing the position board, servo amplifier and servo motor. Failing to do so
Wire the units after installing the position board, servo amplifier and servo motor. Failing to do so
may lead to electric shocks or damage.
Never operate the switches with wet hands, as this may lead to electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this
Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this
may lead to electric shocks.
Do not touch the position board, servo amplifier or servo motor terminal blocks while the power is
ON, as this may lead to electric shocks.
Do not touch the built-in power supply, built-in grounding or signal wires of the position board
and servo amplifier, as this may lead to electric shocks.
2. For fire prevention
CAUTION
Install the position board, servo amplifier, servo motor and regenerative resistor on incombustible.
Installing them directly or close to combustibles will lead to fire.
If a fault occurs in the position board or servo amplifier, shut the power OFF at the servo
amplifier’s power source. If a large current continues to flow, fire may occur.
When using a regenerative resistor, shut the power OFF with an error signal. The regenerative
resistor may abnormally overheat due to a fault in the regenerative transistor, etc., and may lead
to fire.
to fire.
Always take heat measures such as flame proofing for the inside of the control panel where the
servo amplifier or regenerative resistor is installed and for the wires used. Failing to do so may
lead to fire.

Do not damage, apply excessive stress, place heavy things on or sandwich the cables, as this
may lead to fire.
