Data to be used with simple cam function
Memory configuration of cam control data and cam data
• When [AL. F5.2 Cam data miswriting warning] occurs during cam data writing, set [Pr. PT34] to "5010" to
initialize the 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.
*1 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.
CAUTION
• Note that the number of write times to the Flash-ROM where the cam control data and cam data are stored is limited to approximately 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.
Writing method
Description
Temporary writing
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.
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.
Writing
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.
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.
