13 COMMON FUNCTIONS
(Procedure)
1) Power OFF the servo amplifier.
2) Set the key switch of the PLC CPU to STOP.
3) Power the PLC system OFF once, then ON again. If "FALT" is displayed when
the system is powered ON again, the hardware is faulty.
4) Then, correct the contents of the flash ROM.
Perform the parameter initialization function* to initialize the set data
(parameters, positioning data, start block data, condition data) saved in the
flash ROM to the factory settings. After parameter initialization, switch power
OFF once, then ON again.
5) Set the data, such as the parameters, positioning data, start block data and
condition data, to the buffer memory, and turn ON the PLC READY signal
(Y1D). At this time, make sure that the AD75 READY signal (X0) turns OFF. If
it does not turn OFF, any of the parameter settings is in error. Turn OFF the
PLC READY signal (Y1D), refer to the error code ( Md.33 Axis error No.), and
correct the parameter. Turn ON the PLC READY signal (Y1D) again, and
make sure that the AD75 READY signal (X0) turns OFF.
6) Turn OFF the PLC READY signal (Y1D) and execute write to flash ROM. (It
need not be executed when save to flash ROM is not necessary.)
* The parameter initialization function initializes all data saved in the flash ROM
to the factory settings. When it is not desired to initialize data other than the
parameters, back them up using the file register, etc., and then initialize the
parameters.
