9.5.7 Data to be used with simple cam function

CAUTION
(1) Memory configuration of cam control data and cam data
The cam control data and the cam data used for the simple cam are stored in Flash-ROM inside the
servo amplifier. When the power is turned on, the cam data and the cam control data are copied from
the Flash-ROM to the RAM inside the servo amplifier, and then cam control will be executed.
Writing
MR Configurator2
Reading
Temporary
writing
Note. When the power is turned on, the cam data and the cam control data are copied from the Flash-ROM to the RAM.
Use MR Configurator2 to write the cam data and cam control data.
Be sure to write the cam data and the cam control data in servo-off state.
Two writing methods are available.
Writing method
Write the cam control data and the cam data to the RAM of the servo amplifier. After writing, the cam control
data and the cam data will be reflected.
Temporary writing
The written data will be disabled after the power turns off.
Use this when creating and adjusting the cam control data and the cam data.
Write the cam control data and the cam data to the Flash-ROM. The data will be enabled when the power is
cycled after writing.
Writing
After cycling the power, control is performed based on the written data.
Conduct this after the cam control data and the cam data are finalized.
The number of write times to the Flash-ROM where the cam control data and cam
data are stored is limited to 10000. If the total number of write times exceeds
10000, the servo amplifier may malfunction when the Flash-ROM reaches the end
of its useful life. If data needs to be changed very frequently, use the temporal
writing function and write the data to the RAM, not to the Flash-ROM.
POINT
When [AL. F5.2 Cam data miswriting warning] occurs during cam data writing,
set [Pr. PT34] to "5010" to initialize the cam data.
