Chapter 9 Major Positioning Control
9.1.4 Confirming the current value
Values showing the current value
The following two types of addresses are used as values to show the position in
the Simple Motion module.
These addresses ("current feed value" and "machine feed value") are stored in the
monitor data area, and used in monitoring the current value display, etc.
Current feed value
This is the value stored in "
Md.20
Current feed value
".
This value has an address established with a "machine OPR" as a
reference, but the address can be changed by changing the current
value to a new value.
Machine feed value
This is the value stored in "
Md.21
Machine feed value
".
This value always has an address established with a "machine OPR"
as a reference. The address cannot be changed, even if the current
value is changed to a new value.
The "current feed value" and "machine feed value" are used in monitoring the
current value display, etc.
