11.5 Current Value Change Function
11.5 Current Value Change Function
The "current value change function" changes the value set in " Current feed value" to a specified value.
Use this function when operation cannot be started due to a current feed value outside the stroke range, or to change
the current value.
(1) Control detail
As a new address is set in " New current value" and "1" is written in " Current value change request",
" Current feed value" changes to the value set in " New current value".
" Actual current value" is equal to " Current feed value - Accumulated pulses in the deviation
counter". When the accumulated pulse amount in the deviation counter is 0, " Current feed value" is equal
to " Actual current value".
(2) Precautions for control
• If "1" is set in " Current value change request" when BUSY signal (X14) is on, the error "Current value
change error" (error code: 110) occurs and the current value is not changed.
• If the current value is changed to a value outside the stroke limit range, an error does not occur.
(3) Data setting and the execution condition of the function
The following table lists the data to be set and the condition to execute the current value change function.
