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 home position
return" as a reference, but the address can be changed by changing the
current value to a new value.
The "current feed value" and "machine feed value" are used in monitoring the current value display, etc.
