Wiring
■
1. Connection to robot controller
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.
2. Wiring safety points
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.
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.
3. Wiring method
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.
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.
4. Precautions for cable routing and installation
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.
5. Protective measures against electrical shock
WARNING
BE SURE TO GROUND THE CONTROLLER USING THE GROUND TERMINAL ON THE POWER TERMINAL BLOCK. POOR
GROUNDING MAY CAUSE ELECTRICAL SHOCK.
