1.2 PRELIMINARY TROUBLESHOOTING
Prior to following error code troubleshooting procedures, ensure preliminary trouble-
shooting steps are completed.
1. Ensure proper 460 VAC three-phase power is available at the input and output side
of the controller main disconnect (circuit breaker F1).
2. Ensure circuit breakers F2, F3, F4, and F5 are not tripped.
3. Ensure proper +5 VDC, +12 VDC, -12 VDC and +24 VDC are available from the
AVR power supply.
4. Observe the state of LEDs and refer to the appropriate section of the D Series
Controller Electrical Maintenance Manual for conditions indicated by the LEDs. If
these conditions are not normal, correct the cause of abnormal LED indications.
5. Check for loose connection at circuits boards and cable connections.
6. Ensure all circuit boards are properly seated in the card rack (where applicable).
7. Ensure the F1 and F2 fuses on the 1KP board are not open.

TROUBLESHOOTING
1.2.1.1 CONTROLLER POWER CANNOT BE SET TO ON
This failure occurs when the controller does not power-up when the controller main
disconnect is set to ON.
Failure 1: When the controller main disconnect is set to ON, circuit breaker F1 is tripped
immediately.
Main causes include:
1. The AC power line is short-circuited in the controller, and circuit breaker F1 detects
overcurrent and is tripped.
2. Defective F1 circuit breaker.
⇒ Interrupt the 460 VAC to the main disconnect (circuit breaker F1) set the controller
main disconnect to ON. Using an ohm meter check for a short circuit between these
points:
R and S, S and T, T and R, R and FG, S and FG, T and FG (FG=frame ground)
If a short circuit is detected replace components as necessary (wiring, transformer
T1, circuit breaker F1, etc.).
Failure 2: When the main disconnect is set to ON, the control power lamp does not
illuminate (circuit breaker F1 does not trip).
This failure occurs when the controller does not activate properly because of an abnor-
mality in the primary power supplied to the controller or in the power supply circuit in the
controller.
Main causes include:
1. The primary power voltage supplied to the controller is not within specifications, the
primary power cable is disconnected or damaged, or the primary power is not
supplied.
2. Power is not supplied to the 1KQ/1NR board, or the 1KQ/1NR board is defective.
3. Power is not supplied to the AVR power supply.
4. Power is not supplied to the control power lamp due to a defective AVR power
supply, 1KX/1NR board, 1LS/1NS board or control power lamp.
5. Disconnected or short-circuited wiring in the controller.

control power lamp is illuminated.
Failure 1: The control power lamp is illuminated and the teach pendant is inoperable
(the back light is not illuminated).
DC power is supplied to the controller, but power is not supplied to the teach pendant to
illuminate the display or back light.
Main causes include:
1. +12 VDC is not supplied to the teach pendant.
2. Defective LCD panel, circuit board, or other internal teach pendant components.
3. Disconnected or short-circuited teach pendant cable.
⇒ Ensure the teach pendant cable is properly connected to the controller.
⇒ Replace the teach pendant.
⇒ Replace the teach pendant cable.
Failure 2: The back light is illuminated, but the screen is not displayed.
When the teach pendant back light is illuminated this indicates power is supplied to the
teach pendant. If the teach pendant is operating normally the initial screen is displayed
regardless of the 1KA board condition.
Main causes include:
1. Defective LCD panel, circuit board, or other internal teach pendant components.
⇒ Replace the teach pendant.
Failure 3: The teach pendant screen is displayed and the back light is illuminated, but
key input and AS Language commands are not possible.
This condition occurs when key input and AS Language commands do not reach the

ERROR CODE D1007
Regenerative time over [XX].
This error occurs when current is sent to regenerative resistors for six or more consecu-
tive seconds.
When the robot decelerates, the motors enter the power generation state to absorb the
inertia energy from the arm. When the P-N power voltage exceeds the rated value (390
VDC), the current is split from the power block to the regenerative resistor. When the
voltage drops to a safe level (365 VDC) the resistor is removed from the circuit.

2.1
GENERAL SAFETY PRECAUTIONS ON REPLACEMENT
This section describes the precautions to be taken when replacing parts due to trouble, etc.
This information is presented here for use as general precautions. In addition to these,
adhere the safety measures required for each replacement procedure.
CAUTION
！
Parts replacement duties are limited to personnel who have
completed special training and education for the installed
robot or for an equivalent model.
1. Read and understand thoroughly all manuals, specifications and related documents
provided by Kawasaki before operation.
2. Before entering the safety fence (safeguarded space), make sure all necessary safety
measures are prepared and functioning well.
3. Before starting replacement work, shut OFF control power up to the main power source.
Display signs indicating clearly “POWER CUT-OFF IN PROGRESS” or
“REPLACEMENT IN PROGRESS”, and lock out/tag out the main power switch to
prevent personnel from accidentally turning ON the power.
4. Before starting replacement work, secure enough space around the robot so there is no
danger of interference with peripheral systems. Set the peripheral systems in a fixed
status so they will not make any sudden motion.
5. Disable automatic operation functions when entering the safety fence. If the robot
makes any abnormal motion, press EMERGENCY STOP switch immediately, and
evacuate on a planned path of retreat.
6. In addition to the EMERGENCY STOP switch held by the technician, install another
E-STOP switch for the supervisor outside the safety fence, in a place where the robot’s
entire motion range can be monitored. If the robot moves abnormally during
observation of the replacement, the E-STOP switch should be accessible and easy for the
supervisor to press. After an E-Stop, reset and restart robot operations from outside the
fence. Moreover, monitoring duties are limited to personnel who are trained and
qualified.

s
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.

18. Printed boards and power blocks are designed differently for each robot model. Be sure
to replace the correct type.
19. When air or water is supplied, shut OFF the supply source and purge any remaining
pressure from the lines before starting any replacement procedure.
20. Use lighting of 1500 lux or more to avoid mistakes when reading data or replacing
defective parts.
21. After completion of replacement, confirm that the controller functions with no
abnormality.
2.2
REPLACEMENT PROCEDURE FOR PARTS IN CARD RACK
In the card rack of D3x controller, the 1KP board (power sequence board), 1KB board (arm
control board), 1KA board (user I/F board), optional board, and the AVR are housed from the
left as shown below. For D7x controller, the 1NR board (brake control board) is housed in
the leftmost of the card rack.

2.2.1 1KA BOARD (USER I/F BOARD)
1. This is the user I/F board used for storing taught pose data, user program data, etc. in
memory. Before replacing the board, be sure to save all data to storage media such as
PCCARD, FDD, etc. For more details about data saving procedures, refer to the
Operation Manual, a separate volume.
2. After completion of data saving, turn OFF the control power.
3. Press the red button on the ejector of the 1KA board to release the lock, and pull out the
1KA from the card rack by extending the ejector up and down.
4. When replacing only the 1KA, disassemble daughter boards, 1KK, 1KN/1QN and
1KJ/1QJ, by removing their connecting screws to the 1KA and then the daughter boards.
5. Confirm that settings for SW1 and SW2 on the new 1KA are the same as before board
replacement. For the daughter boards disassembled in step 4, reassemble them to the
new 1KA.
6. Insert the new 1KA to the card rack and set it in the mother board.
7. Turn ON the SW2-8 on the 1KA.
8. Turn ON the control power. When the initialization prompt is displayed on the teach
pendant display, select “999: Initialization of all data”.
9. When the confirmation query for initialization is displayed, select “1: YES”.
10. After completion of initialization, load all data saved before board replacement to the
1KA. For more details about data loading procedure, refer to the Operation Manual, a
separate volume.
11. Turn OFF the SW2-8 on the 1KA.

REPLACEMENT PROCEDURE FOR BATTERIES
This section describes the replacement procedure for the battery provided to backup data.
2.8.1 BATTERY ON 1KA BOARD
As backup power supply for SRAM and RTC (Real Time Clock), the 1KA board is equipped
with a lithium battery and an emergency super capacitor for use during battery replacement.
When on-board battery is removed, fully charged super capacitor can provide backup power
for only 15 minutes. Therefore, battery should be replaced immediately once the control
power is cut OFF.
CAUTION
！
To prevent data erasion, be sure to save program data
as soon as it is completed.
1. Before replacing the battery, confirm that the new battery has +3.6V or more voltage.
2. Turn OFF the control power.
3. Remove the battery connector of the 1KA and pull out the battery from the holder. When
it is hard to work on, pull out the 1KA. For more details about pulling out the board,
refer to 2.2.1 1KA Board (User I/F Board).
4. After installing the new battery to the holder, connect the battery connector. If the 1KA
was pulled out, put it back to the original place.

CAUTION
！
1. Battery life is about year and a half (assuming control power is OFF
continuously), but longevity differs depending on ambient temperature, etc.
2. The encoder assembly contains a super capacitor that maintains memory
power for approximately 30 minutes. In order to maintain encoder data
when replacing the 1FG batteries or disconnecting the encoder from the
1FG board, the batteries must be replaced or the encoder reconnected
within the 30 minutes period. (Take note that if the super capacitor is not
fully charged, encoder data may not be maintained for the full 30 minutes.)
