PARAMETERS
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.
z List of calibration parameters
[Special monitor selection No.]
Refer to page 117 for details of the monitor description.
∗1 The data format is 6 digits (E2) when the following conditions are met: Pr. 37 = "0.01 to 9998," Pr. 144 = "2 to 10," and the instruction code HFF = "01."
(Refer to page 115 for Pr. 37 and Pr. 144.)
∗2 Input terminal monitor details (when the terminal is ON: 1, when the terminal is OFF: 0, —: undetermined value)
∗3 Output terminal monitor details (when the terminal is ON: 1, when the terminal is OFF: 0, —: undetermined value)
∗4 The monitored values are retained even if an drive unit fault occurs. Resetting will clear the retained values.
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 an drive unit reset or
all clear is performed.
