Code Meaning Remedy
171 Communication check sum error of
Servo CPU. 1) Eliminate external noise source and execute VERINIT com-
mand. (Refer to the section 2.6 in the functions volume.)
2) If this error frequently occurs, replace or repair the MPU
board. (Refer to the section 7.3 in the maintenance vol-
ume.)
172 Instructive motor torque is abnormal. Check disconnection of the motor power line in manipulator and
controller. (Refer to the manipulator manual and “2.3 Diagram
of cable connections” in the maintenance volume of this man-
ual.)
173 Robot is in low power state. Motor
output power is limited.

•
When the red LED on the front of
the AC servo driver is off.
1) External noise source exists.
•
When the red LED on the front of
the AC servo driver is lit.
2) Weight of the end effector and
work piece exceeds rated pay-
load.
3) Motion duty of manipulator is too
much.
4) Mechanical load is added on axis.
5) Tension of the timing belt is not
proper.
6) The cooling fan is not function-
ing.
7) The filter is clogged.
8) Ambient temperature around con-
troller is over 40
°
C.
9) The motor power line is shorted
or grounded.
10) Other than the above.
1) Eliminate external noise source and execute VERINIT com-
mand. (Refer to the section 2.6 in the functions volume.)
If no external noise source exists, replace MPU board.
(Refer to the section 7.3 in the maintenance volume.)
2) Check actual weight, and set proper WEIGHT. (Refer to
the section “Load weight and the WEIGHT setting” of ma-
nipulator manual.)
3) Reduce operation speed of robot. (Refer to ACCEL,
SPEED and WEIGHT command of the reference manual.)
4) Check each axis motion moving by the hand. Verify appro-
priate lubrication or replace reduction gear. (Refer to the
manipulator manual.)
5) Check the tension of timing belt. Tighten or replace if neces-
sary. (Refer to the section “Replacing the timing belt” of
manipulator manual.)
6) Inspect the cooling fan. Replace it if necessary. (Refer to
the section 12.2 of the maintenance volume.)
7) Clean the filter of cooling fan. (Refer to the section 12.1 of
the maintenance volume.)
8) Cool the place where the controller is.
9) Check disconnection of the motor power line in manipulator
and controller. (Refer to the manipulator manual and “2.3
Diagram of cable connection” in the maintenance volume of
this manual.)
10) Replace the AC servo driver. (Refer to the section 6.3 of
the maintenance volume.)
