Wiring
■
Connection to robot controller 1.
The controller parameters are preset at the factory before shipping to match the robot model. Check the specified robot
and controller combination, and connect them in the correct combination.
Since the software detects abnormal operation such as motor overloads, the controller parameters must be set correctly
to match the motor type used in the robot connected to the controller.
Wiring safety points 2.
w
WARNING
Always shut off all phases of the power supply externally before starting installation or wiring work. Failure to do
this may cause electrical shock or product damage.
c
CAUTION
• Make sure that no foreign matter such as cutting chips or wire scraps get into the robot controller. Malfunction,
breakdown or fire may result if these penetrate inside.
• Do not apply excessive impacts or loads to the connectors when making cable connections. This might bend
the connector pins or damage the internal PC board.
• When using ferrite cores for noise elimination, be sure to fit them onto the power cable as close to the robot
controller and/or the robot as possible, to prevent malfunction caused by noise.
Wiring method 3.
w
WARNING
Securely install the connectors into the robot controller and, when wiring the connectors, make the crimp,
press-contact or solder connections correctly using the tool specified by the connector manufacturer.
c
CAUTION
When disconnecting the cable from the robot controller, detach by gripping the connector itself and not by
tugging on the cable. Loosen the screws on the connector (if fastened with the screws), and then disconnect the
cable. Trying to detach by pulling on the cable itself may damage the connector or cables, and poor cable
contact will cause the controller or robot to malfunction.
Precautions for cable routing and installation 4.
c
CAUTION
• Always store the cables connected to the robot controller in a conduit or clamp them securely in place. If the
cables are not stored in a conduit or properly clamped, excessive play or movement or mistakenly pulling on
the cable may damage the connector or cables, and poor cable contact will cause the controller or robot to
malfunction.
• Do not modify the cables and do not place any heavy objects on them. Handle them carefully to avoid
damage. Damaged cables may cause malfunction or electrical shock.
• If the cables connected to the robot controller may possibly become damaged, then protect them with a
cover, etc.
• Check that the control lines and communication cables are routed at a gap sufficiently away from main power
supply circuits and power lines, etc. Bundling them together with power lines or close to power lines may
cause faulty operation due to noise.
Protective measures against electrical shock 5.
w
WARNING
Be sure to ground the ground terminals of the robot and controller. Poor grounding may cause electrical shock.
