Cause of error
• If the problem continues
to occur frequently after
the encoder power is
turned ON again, replace
the Servomotor.
• Replace the Servo
Driver.
• Correct the encoder's
peripheral wiring (sepa-
rating the encoder and
power lines, grounding,
etc.).
• If the problem occurs fre-
quently, replace the Ser-
vomotor.
• Replace the Servo
Driver.
• Set the Servomotor to
rotate at less than
200 r/min when the
encoder power is turned
ON.
• Replace the Servomotor.
• Replace the Servo

• Replace the Servomotor.
• Replace the Servo

• Replace the Servomotor.
• Replace the Servo

• Lower the Servomotor's
ambient temperature to
40 ° C or less.
• Operate the Servomotor
with a load that is no
more than the rated load.
• Replace the Servomotor.
• Replace the Servo
Driver.
• Replace the Servo
Driver.
