Current value change
When the current value is changed from 2000 to 1000, the current feed value changes to 1000, but the machine feed value
remains 2000.
• When the machine feed value is set as a limit, the machine feed value of 5000 (current feed value: 4000) becomes the
upper stroke limit.
• When the current feed value is set as a limit, the current feed value of 5000 (machine feed value: 6000) becomes the upper
stroke limit.
When Machine feed value is set in [Pr.14] Software stroke limit selection, the movable range becomes an
absolute range based on the OP. When Current feed value is set, the movable range becomes a relative
range from Current feed value.
Details of the software stroke limit check
*1 Select either [Md.20] Current feed value or [Md.21] Machine feed value in [Pr.14] Software stroke limit selection.
*2 Movable range from [Pr.12] Software stroke limit upper limit value to [Pr.13] Software stroke limit lower limit value
Check detail Processing when an error occurs
(1) An error occurs if the current value
*1
is outside the software stroke limit range
*2
.
(Check [Md.20] Current feed value or [Md.21] Machine feed value.)
Software stroke limit (+) (Error code: 1993H) or Software
stroke limit (-) (Error code: 1995H) occurs.
(2) An error occurs if the command address is outside the software stroke limit range.
(Check [Da.6] Positioning address/movement amount.) Software stroke limit (+) (Error code: 1A18H) or Software
stroke limit (-) (Error code: 1A1AH) occurs.
