Troubleshooting
ò The procedures in the section are intended only for technicians who have received
proper training and certification from the manufacturer.
Do not attempt to perform procedures for which you are not qualified.
Whenever you encounter a malfunction, try to pinpoint its source by exchanging the
suspected faulty component—for example, servo control card, control box, robot arm,
PC, cables—with an identical component from a working system.
Do not open the control box. There are no user-serviceable parts inside. Do not attempt
repairs for which you are not qualified. Contact your agent or an authorized technician
for repairs.
The following chart provides guidelines for identifying and rectifying problems which
you may encounter. Refer also to the Controller-PC User’s Manual for additional
troubleshooting instructions and information.
1. Controller functioning, but the robot cannot be activated.
•
Make sure an obstacle is not blocking the robot.
•
Make sure none of the axes has reached its mechanical limits.
•
Make sure the controller’s green MOTORS LED is lit.
•
Make sure the controller is in the Control Off state. Then activate the Control On
state from the PC or TP.
•
Make sure the robot cable is properly connected to the controller.
2. Robot does not find Home position in one or all of the axes.
•
Make sure the homing command was properly issued.
•
Make sure the robot cable is properly connected to the controller.
•
Make sure system homing parameters are properly set.
Make sure system homing parameters have not been erased.
•
Check the microswitch for this axis. Prepare and run a simple program to test the
microswitch (on axis 2 for example), as follows:
Set Variable LIMIT_SWITCH = 2
If Limit switch LIMIT_SWITCH jump to TURN_ON
turn off output LIMIT_SWITCH
Jump to END
TURN_ON:
turn on output LIMIT_SWITCH
END:
