Memory Configuration and Role
6.1.1
Memory configuration
Store parameters and data necessary for control in the buffer memory (BFM) and flash memory inside the
20SSC-H using FX Configurator-FP (setting/monitoring tool)
*1
or a sequence program.
1) Buffer memory (BFM)
The PLC can access the buffer memory (BFM) directly, using sequence programs.
The 20SSC-H uses positioning parameters and data in this area to execute positioning control.
2) Flash memory
The flash memory saves parameters and table information necessary for positioning control.
Store necessary data in advance for the mechanical equipment and applications.
Servo parameters stored in the flash memory or buffer memory are transferred to the servo amplifier in
accordance with the setting of positioning parameters. The servo amplifier will perform control using the
transferred servo parameters. (In the 20SSC-H whose version is earlier than Ver.1.10, servo parameters
stored in the flash memory are transferred to the sevo amplifier.)

For the parameter setting, refer to Section 7.1
*1.
FX Configurator-FP Ver. 1.30 or later can set parameters and data via the FA transparent function of
the GOT1000 Series (only the GT15 and GT11 Series).
