6.9 Tracing Data

The data trace function allows a host controller to read I/O information and operating data col-
lected in the Servo Driver's memory via the DeviceNet.
By implementing trace settings, data is collected in the Servo Driver's memory. Then, by imple-
menting trace data reading, the collected data can be read from a host controller by means of
Explicit Messages.
The following table provides an outline of the data trace function.

Note 1. It takes approximately one minute from the beginning of the tracing until the end.
2. Trace parameters are not saved when the Unit is reset. When the power is turned OFF, the
