3 DESIGN
Refer to section 3.2
Refer to section 3.2.1
Refer to section 3.2.2
Refer to section 3.3
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.
External circuit design
Power supply circuit design
Safety circuit design
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.
Layout design within control panel
Layout design based on the design environment such as temperatures
and vibrations in consideration of heat generated from modules and
handling of module installation.
!
CAUTION
Provide appropriate circuits external to the Motion CPU 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 CPU
failure.
Install the Motion controller, servo amplifier, servomotor, and regenerative resistor on inflammable
material. Direct installation on flammable material or near flammable material may 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 installed 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.
