NSK EDD Megatorque Motor - RS-232 C Communication Positioning

6. Operation
— 6-31 —
6.3.5. RS-232C Communication Positioning Operation
 Positioning may be executed directly via RS-232C communication.
 The commands and parameters related to the positioning operations are listed in “Table 6-5: Positioning
command and parameter” and the commands and parameters unique to RS-232C communication
positioning are listed in “Table 6-12: Command and parameter related to the RS-232C communication
positioning” below. Refer to “9. Details of Command and Parameter” for details.
 Refer to “8.9. RS-232C Communication” for the detail of the way of communication.

Caution : Please note that there is the limit for the number of times of overwriting
commands and parameters to the memory.
 The Driver Unit has an EEPROM for the data backup. The EEPROM has the
limitation on the number of times for writing and deleting data. (Approximately 100
000 times) Therefore, we recommend setting the command WM to prohibit writing
to the EEPROM when the internal parameters are frequently changed from the
master controller during operation. However, setting of the command WM is not
necessary for commands and parameters that do not require the backup.
 Parameters that are categorized as “parameter” in “9. Details of Command and
Parameter” will be backed up on the EEPROM.
