11.6 Parameters That Are Automatically Updated
Some of the parameters stored in SERVOPACK RAM may be overwritten automatically under certain conditions or as
a result of self-configuration. This includes MP2000-series Machine Controller setting parameters and fixed parame-
ters, as well as fixed value SERVOPACK parameters. Some SERVOPACK parameters are also written to setting
parameters automatically during self-configuration. The parameters that are updated automatically under specific con-
ditions are listed in the following tables.
Refer to
Chapter 4 Motion Parameters
for details on Machine Controller parameters. Refer to your SERVOPACK
manual for details on SERVOPACK parameters.
11.6.1 Parameters Updated when a MECHATROLINK Connection Is Established (1)
(User Constants Self-writing Function Enabled)
The Machine Controller parameter settings in the left table below are automatically written to the SERVOPACK
parameters given in the right table below when a connection is established between the Machine Controller and the
SERVOPACK. This occurs after power is turned ON or alarms are cleared following a communication interruption.
The parameters are written only when User Constants Self-writing Function is enabled when bit A of fixed parameter 1
in the Machine Controller is set to 0.
* 1. Updated when using MECHATROLINK-II (10 Mbps, 32 bytes).
* 2. When Pn833.0 is set to 0, Pn80B will be updated. When Pn833.0 is set to 1, Pn836 will be updated.
* 3. When Pn833.0 is set to 0, Pn80E will be updated. When Pn833.0 is set to 1, Pn83C will be updated.
