7. Use only Kawasaki approved parts during replacement.
8. When replacing printed boards, do not fail to turn OFF control power. To replace
power block, MC unit, or AVR, wait at least seven minutes after control power OFF
before removing connectors. Then confirm that output voltage from the DC power
source and the P-N voltage are 0V.
9. During operation, both technician and supervisor must always watch out for abnormal
motion and possible pinch points in and around the robot.
10. Semiconductors are often used in printed boards. Note that these semiconductors are
sensitive to static electricity, be sure to discharge any electrostatic on the body before
handling the printed boards.
11. Directly touching the parts containing semiconductors may cause electrostatic discharge
damage. When handling printed boards, do not touch the semiconductors directly but
hold the periphery of the printed boards. If parts must be touched directly, confirm that
electrostatic on the body has been discharged.
12. Putting printed boards directly onto the controller, etc. may cause electrostatic discharge
damage. Be sure to put them on an electrostatic-proof mat board or sheet, or enclose
printed boards in an electrostatic-proof bag.
13. Avoid removing printed boards at control power ON, or turning the control power ON
without any printed boards mounted.
14. Take a record of all data settings currently on controller, printed boards, etc. so the
system can be restored to its normal operating condition.
15. To prevent displacement of the robot, take a record of the robot’s pose before starting the
replacement procedure.
16. Be sure to connect connectors and cables correctly. When using connectors equipped
with locks, do not fail to lock after insertion. Do not touch connector pins.
17. Immediately after robot movement, the heat sink, the regenerative resistor, etc. may be
very hot. Do not touch the power block unit directly, there is a danger of burn.
