3 DESIGN
Layout design based on the design environment such as
temperatures and vibrations in consideration of heat generated
from modules and handling of module installation.
Power supply circuit design
Safety circuit design
Layout design within control panel
Design the power supply circuit which supplies power to such
system components as the Motion controller, I/O equipment and
servo amplifiers, etc., taking into consideration the protective
coordination and noise suppression techniques.
Design the operation-ready circuit which stops the system at
occurrence of any alarm such as a Motion controller or servo
amplifier alarm or the emergency stop, the circuit which avoids
a malfunction while power is unstable at power-on, and the
electromagnetic brake circuit for servomotors.

External circuit design
CAUTION
Provide appropriate circuits external to the Motion controller to prevent cases where danger may
result from abnormal operation of the overall system in the event of an external power supply fault
or Motion controller failure.
Mount the Motion controller, servo amplifier, servomotor and regenerative resistor on
incombustible. Mounting them directly or close to combustibles will lead to fire.
If a fault occurs in the Motion controller 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.
Always take heat measures such as flame proofing for the inside of the control panel where the
servo amplifier or regenerative resistor is mounted and for the wires used. Failing to do so may
lead to fire.
Do not apply a voltage other than that specified in the instruction manual on any terminal. Doing
so may lead to destruction or damage.
Do not mistake the polarity ( + / - ), as this may lead to destruction or damage.
