Communication operation and setting
Example) When reading the C3 (Pr.902) and C6 (Pr.904) settings from the drive unit of station 0
To read/write C3 (Pr.902) and C6 (Pr.904) after drive unit reset or parameter clear, execute from 1) again.
List of calibration parameters
[Special monitor selection No.]
Refer to page 156 for details of the monitor description.
When "0.01 to 9998" is set in Pr.37 and "01" in instruction code HFF, the data format is 6 digits (E2).
Input terminal monitor details (when the terminal is ON: 1, when the terminal is OFF: 0, : undetermined value)
Output terminal monitor details (when the terminal is ON: 1, when the terminal is OFF: 0, : undetermined value)
REMARKS
Set 65520 (HFFF0) as a parameter value "8888" and 65535 (HFFFF) as "9999".
For the instruction codes HFF, HEC and HF3, their values are held once written but cleared to zero when a drive unit reset or all
clear is performed.
