*1 For the overload characteristics, refer to 3-2 Overload Characteristics (Electronic Thermal Function) on page 3-25.
*2 Always provide a temperature fuse or other protective measure when setting the External Regeneration Resistor Setting
(3017 hex) to 2. Otherwise, the Regeneration Resistor will not be protected, generate excessive heat, and be burned out.
G5 Series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type
Cause
For details, refer to Troubleshooting Errors Related to EtherCAT Communications on page
12-20.
Electronic gear ratio exceeded the allowable
range.
The set value of the External Feedback
Pulse Type Selection (3323 hex) differs from
the external encoder type that is actually
connected for serial communications.
The function that was set does not support
the communications cycle.
• The electronic gear object ratio was not
1:1 when the communications cycle was
set to 250/500 s.
• Homing mode (hm) was set in Modes of
operation (6060 hex) when the
communications cycle was set to 250 or
500 s.
• A mapping exceeding 20 bytes was set in
an RxPDO when the communications
cycle was set to 250 s.
• The number of bytes (objects) mapped to
RxPDO is 0.
• 11 or more objects were mapped to
RxPDO.
• 12 or more objects were mapped to
TxPDO.
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.
12 Troubleshooting and Maintenance
Measures
Check the object settings. The electronic
gear ratio must be set between 1/1000 and
1000.
Set object 3323 hex to conform with the
external encoder type that is actually
connected.
• Check the communications cycle settings
or the electronic gear object.
• Check the communications cycle settings
or control mode settings.
• Check the communications cycle settings
or the mode of operation.
• Check the communications cycle settings
or the number of bytes of mapping.
• Check the number of bytes of mapping or
the parameters for the control mode
settings.
• Check the number of mapped objects.
• Check the mapped objects.
• Turn OFF the power once, and turn it ON
again.
• If the error is displayed even after the
power is turned ON again, the system may
be faulty. Stop using the system, and
replace the motor and/or the Servo Drive.
Return the Servo Drive to the dealer that it
was purchased from and ask for
investigation and repair.
