5-3-3 Timing Chart for Reading Data
Reading data is possible even during axis operation.
It is not possible to write and read data at the same time.
The following diagram is a timing chart for reading data from a 4-axis PCU.

64 Hex (100)
After the data reading operation has been completed, the Data Transferring Flag
(word n+8, bit 14) is turned from ON to OFF. If an error occurs during data trans-
fer, the Error Flag (word n+8, bit 12) will be turned ON and the error code will be
output to n+10 in the operating memory area. Check this error code to determine
the cause of the error and correct it.
