Transferring and Saving Data Section 5-1
4. There is a limit on the number of times you can read something using the
flash memory. Set this so that up to 100,000 data saving operations can be
performed.
5-1-3 Data that Can be Saved and/or Transferred
All the following data used by the PCU can be read, written, and saved to the
flash memory. The timing with which transferred data is enabled varies
according to the type of data. For details on the enable timing of the axis
parameters, refer to
4-4 Axis Parameter Area . Data other axis parameters
(e.g., positioning sequences and positions) will be enabled immediately after it
is transferred.
Note The following types of data can be saved together in the flash memory.
• Axis parameters (see note)
• Positioning sequences
• Speeds
• Positions
• Acceleration times
• Deceleration times
• Dwell times
• Zones
Note When the power is turned ON or when the PCU is restarted, a choice is avail-
able by using the axis parameter designation setting in the DM Area common
parameters (refer to
4-3 Common Parameter Area ) between sending the axis
parameters automatically from the DM Area to the PCU or using the axis
parameters saved in the PCU.
5-1-4 Data Addresses
Each data item has its own address in the PCU, and this address is used to
identify the write destination and read source when data is transferred. One
word (16 bits) is used to designate each address. It is not possible to transfer
data extending across axis parameters and data for the X, Y, Z and U axes.
Note When transferring an item of data, transfer the data for all the words allocated
to that item. For details of the word configurations for data, refer to
SECTION
4 Data Areas .
