POINT
(1) Execute the parameter initialization when the positioning control do not
execute (PLC READY signal [Y0] OFF). An "error code 1903" will occur if it is
executed at the PLC READY signal [Y0] ON.
(2) A writing to the flash ROM is up to 100,000 times. If writing exceeds 100,000
times, the writing may be become impossible, and an "error code 1901" will
occur.
(3) Be sure to turn the system power supply ON/OFF or reset the PLC CPU after
the parameter initialization.
(4) The number of the flash ROM write with the sequence program after the single
system power supply ON or single PLC CPU reset is limited to up to 25.
Writing of the 26th times will cause an "error code 1902".
(5) The number of parameter initialization after the system power supply ON can
be monitored in "
(6) The parameter initialization can be executed, after the system's power supply
ON and the PLC READY signal [Y0] ON. If the parameter initialization is
executed without turning ON the PLC READY signal [Y0] after the system's
power supply ON, a "warning code 10001" will occur and the parameter
initialization cannot be executed.
