Troubleshooting
Deviation
counter over-
flow
Servomotor will
not rotate even
when command
pulses are input.
Servomotor power or
encoder line is wired incor-
rectly.
Rewire correctly.
Locked mechanically
Repair if the Servomotor shaft
is locked
Control panel error
Replace the Servo Driver.
Occurs when
rotating at high
speed
Servomotor power or
encoder line is miswired.
Rewire correctly.
Occurs when long
command pulses
are sent
Gain adjustment is insuffi-
cient.
Adjust the gain.
Acceleration and decelera-
tion is too violent.
Lengthen acceleration and
deceleration time.
Use position command filter
(Pn207.0, Pn204, and Pn208).
Load is too large.
Lighten the load.
Reselect the Servomotor.
Pn505 (deviation counter
overflow level) setting is too
large.
Reset the parameter correctly.
Resolution setting switch
(switches 4 and 5) setting is
too low.
Reset the switches correctly.
Pn202 and Pn203 (elec-
tronic gear ratio) setting is
too large.
Reset the parameters correctly.
Parameter
Unit transmis-
sion error 1
Occurs when
power supply is
turned ON.
Faulty Connector contact.
Plug the Connector in securely.
Internal element malfunc-
tion.
Turn OFF the power supply,
then ON again.
Internal element is faulty.
Replace the Servo Driver.
Replace the Parameter Unit.
