Runs or stops programs. This command cannot be issued in setting
lev el 1.
• Remote/Local (number of writings: 100000 operations)
Selects remote operation or local operation.
• RAM Write mode (number of writings: 100000 operat ions)
In the RAM mode, the local SP (set point and set points 0 to 3) are
saved to RAM, and in the backup mode, the local SP is saved to EE-
PROM.
• RAM data Save
When this command is issued, set points are saved to EEPROM.
