5 DATA USED FOR POSITIONING CONTROL
5.1.7 Types and roles of monitor data
The monitor data area in the buffer memory stores data relating to the operating state
of the positioning system, which are monitored as required while the positioning
system is operating.
The following data are available for monitoring.
of the positioning system, which are monitored as required while the positioning
system is operating.
The following data are available for monitoring.
System monitoring:
Monitoring of the QD75 configuration and operation history (through the system
monitor data Md.1 through, Md.19 Md.50 through Md.52
monitor data Md.1 through, Md.19 Md.50 through Md.52
1
)
1: Md.50 through Md.52 are for the QD75P N/QD75D N only.
Axis operation monitoring:
Monitoring of the current position and speed, and other data related to the
movements of axes (through the axis monitor data Md.20 through Md.48 2)
movements of axes (through the axis monitor data Md.20 through Md.48 2)
2:
The axis monitor data are refreshed every 0.9ms (QD75P N/QD75D N) or
1.8ms (QD75P /QD75D ). Note that " Md.21 Machine feed value",
" Md.22 Feedrate", " Md.28 Axis feedrate" and " Md.30 External
input/output signal" of QD75P /QD75D are refreshed every 56.8ms. Also,
" Md.23 Valid M code", is updated when the "M code ON signal [X4, X5, X6,
X7]" turns ON.
