OMNUC G5-Series AC Servo Drives Users Manual (Built-in MECHATROLINK-II communications type)
Cause
Electronic gear ratio exceeded the
allowable range.
External encoder ratio exceeded the
allowable range.
The set value of the External
Feedback Pulse Type Selection
(Pn323) differs from the external
encoder type that is actually
connected for serial communications.
Electronic gear ratio exceeded the
allowable range.
The Servomotor does not match the
Servo Drive.
• An error signal was detected due to
excess noise or some other
problem.
• An alarm was cleared when safety
input 1 or 2 was not in a normal
state (one of the input
photocouplers is not ON).
• The control circuit malfunctioned
due to excess noise or some other
problem.
• The self-diagnosis function of the
Servo Drive was activated, and an
error occurred in the Servo Drive.
11-4 Troubleshooting
Measures
Check the Parameter settings. The
electronic gear ratio must be set
between 1/1000 and 1000.
Check the Parameter settings. The
external encoder ratio must be set
between 1/40 and 160.
Set object Pn323 to conform with the
external encoder type that is actually
connected.
Replace the Servomotor with a
Servomotor that matches the Servo
Drive.
• Turn OFF the power once, and turn
it ON again.
• If the alarm is displayed even after
the power is turned ON again, the
system may be faulty. Stop using
the system, and replace the
Servomotor and/or the Servo
Drive.
• Return the Servo Drive to the
dealer that it was purchased from
and ask for investigation and
repair.
• Clear the alarm when both safety
input 1 and 2 are in a normal state
(the both input photocouplers are
ON).
• Turn OFF the power once, and turn
it ON again.
• If the alarm is displayed even after
the power is turned ON again, the
system may be faulty. Stop using
the system, and replace the
Servomotor and/or the Servo
Drive.
• Return the Servo Drive to the
dealer that it was purchased from
and ask for investigation and
repair.
