*1
For the minimum allowable value, refer to 4-5-2 Servo Drive Regeneration Absorption Capacity on page 4-49.
*2
For the available combinations of External Regeneration Resistors and resistance values, refer to 4-5-4 Connecting an
External Regeneration Resistor on page 4-51.
*3
For the overload characteristics, refer to 3-2 Overload Characteristics (Electronic Thermal Function) on page 3-25.
*4
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.
*5
When Motor Velocity Demand Value After Filtering is forced to “0” during an immediate stop due to a halt or
positive/negative drive prohibition input, the speed deviation immediately increases The speed deviation also increases
when the Motor Velocity Demand Value After Filtering starts. Therefore, provide enough margin when making the
settings.
*6
This operation is performed for safety and is not an error.
*7
The initialization of position data occurs at any of the following four timings.
After the control power was turned ON, after a Config operation, after FFT was executed, and after a trial run was
executed.

4 hex Function
Setting Error
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 µs.
•
Homing mode (hm) was set in Modes
of operation (6060 hex) when the
communications cycle was set to 250
or 500 µs.
•
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 Modes of operation.
•
More than 20 bytes were mapped for
RxPDO when the communications
period was set to 250 µs.
•
Check the communications cycle
settings or the number of bytes of
mapping.
•
The number of bytes (objects) mapped
to RxPDO is 0.
•
Check the number of bytes of mapping
or the parameters for the control mode
settings.
•
More than 10 objects were mapped for
RxPDO.
•
Check the number of mapped objects.
•
More than 11 objects were mapped for
TxPDO.
•
Check the mapped objects.
99 hex
0 hex Other Errors
•
An error was reset when safety input 1
or 2 was not normal (one of the input
photocouplers is not ON).
*9
•
Reset the error when safety inputs 1 and
2 are normal (both input photocouplers
are ON).
*10
•
The control circuit malfunctioned due to
excess noise or some other problem.
•
Turn OFF the power once, and turn it
ON again.
•
The self-diagnosis function of the
Servo Drive was activated, and an error
occurred in the Servo Drive.
•
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 Servomotor and/or the
Servo Drive. Return the Servo Drive to
the dealer that it was purchased from
and ask for investigation and repair.
