Saving Data Section 5-6
• Axis parameters
• Positioning sequences
• Speeds
• Acceleration and deceleration times
• Dwell times
• Zones
Note The data for the number of axes for the particular PCU being used is all saved
at once.
Parameters and other data that have been saved to flash memory are read to
the PCU’s internal memory when the PCU is powered up or restarted. If the
parameters or other data are corrupted at that time, a parameter destruction
error (error code 0001) or data destruction error (error code 0002) will be gen-
erated and the PCU will be started up using the initial values (i.e., the factory
settings) or the parameters and data that had been saved prior to the last
save to flash memory.
If parameters or data are lost, no operation other than data transfer or data
saved can be received. After transferring the data, save the data and turn the
power OFF and then ON again, or restart the PCU.
5-6-2 Data Saving Procedure
Data can be saved using either the SAVE DATA Bit in the operating memory
area or using CX-Position. For details of saving data using CX-Position, refer
to the CX-Position Operation Manual (W433).
