16.3.2 Troubleshooting Warnings
The causes of and corrections for the warnings are given in the following table. Contact your
Yaskawa representative if you cannot solve a problem with the correction given in the table.
93Bh Overheat Warning
The input voltage (temperature) for the overheat protection input (TH) sig-
nal exceeded the setting of Pn61C (261Ch) (Overheat Warning Level).
942h
Speed Ripple Com-
pensation Information
Disagreement
The speed ripple compensation information stored in the encoder does
not agree with the speed ripple compensation information stored in the
SERVOPACK.
971h Undervoltage
This warning occurs before an A.410 alarm (Undervoltage) occurs. If the
warning is ignored and operation is continued, an alarm may occur.
9A0h Overtravel Overtravel was detected while the servo was ON.
9b0h
Preventative Mainte-
nance Warning
One of the consumable parts has reached the end of its service life.

Possible Cause Confirmation Correction Reference
900h:
Position Deviation
Overflow
The Servomotor
U, V, and W wiring
is not correct. Check the wiring of the
Servomotor’s Main Cir-
cuit Cables.
Make sure that there are no
faulty connections in the
wiring for the Servomotor
and encoder.
–
A SERVOPACK
gain is too low. Check the SERVO-
PACK gains.
Increase the servo gain,
e.g., by using autotuning
without a host reference.
page 9-23
The acceleration
of the position ref-
erence is too high.
Reduce the reference
acceleration and try
operating the SERVO-
PACK.
Reduce the acceleration of
the position reference using
an EtherCAT command.
–
The excessive
position deviation
alarm level (Pn520
(2520h)
×
Pn51E
(251Eh)/100) is
too low for the
operating condi-
tions.
Check excessive posi-
tion deviation alarm
level (Pn520 (2520h)
×
Pn51E (251Eh)/100) to
see if it is set to an
appropriate value.
Optimize the settings of
Pn520 (2520h) and Pn51E
(251Eh).

A failure occurred
in the SERVO-
PACK.
–
Turn the power supply to
the SERVOPACK OFF and
ON again. If an alarm still
occurs, the SERVOPACK
may be faulty. Replace the
SERVOPACK.
