Troubleshooting
Overtravel (OT)
(Travelling outside
of the zone speci-
fied by the host
device)
The position is dis-
placed (without an
alarm being out-
put).
Servomotor is
overheating.
Symptom
The FG is fluctuating due
to influence from machin-
ery (such as welders) in
the vicinity of the Servomo-
tor.
The Servo Driver pulse
count is incorrect due to
noise.
There is interference due
to the encoder being sub-
jected to excessive vibra-
tion and shock.
Encoder is defective.
Servo Driver is defective.
The coupling between the
machine and the Servomo-
tor is faulty.
Noise is carried because
the input signal line specifi-
cations are incorrect.
Encoder is defective.
(Pulses are not changing.)
The ambient temperature
is too high.
The Servomotor's surface
is dirty.
There is an overload.
