Timing of Saving Parameters
When the parameters are saved depends on the parameter numbers, as described in the fol-
lowing table.

Resetting the Module
The following operations will be performed when the Module is reset.
• All parameters are saved in non-volatile memory.
• The parameters that require turning the power supply OFF and ON again are enabled.
Refer to the following section for a detailed operating procedure.

These parameters are saved immediately in nonvolatile memory in the SERVOPACK
as soon as they are written.

to Pn6
The settings of some parameters, however, require that you turn the power supply
OFF and ON again or reset the Module to enable changes to the parameter settings.
These parameters are saved in nonvolatile memory in the SERVOPACK at the follow-
ing times.
• When the Module is reset
• When the parameters are saved in flash memory from the SigmaWin+
• When positioning operations are preformed by changing the Start Trajectory bit to 1
after changing the parameters. (About 10 seconds is required to write the parame-
ters.)
Parameters that are not saved immediately in nonvolatile memory are stored in RAM in the
SERVOPACK. To save all parameters in nonvolatile memory after completing parameter adjust-
ments, reset the Module. If the power supply is turned OFF before the Module is reset, any
changes that have been made to the parameters that are not saved automatically will be lost.
