[Current value changing]
When the current value is changed by a new current value command from 2000 to 1000, the current value will
change to 1000, but the machine feed value will stay the same at 2000.
• When the machine feed value is set at the limit, the machine feed value of 5000 (current feed value: 4000)
becomes the upper stroke limit.
• When the current feed value is set at the 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 moveable range becomes an absolute
range referenced on the OP. When "current feed value" is set, the moveable range is the relative range from the "current
feed value".
(2) Software stroke limit check details
*1 Check whether the "[Md.20] Current feed value" or "[Md.21] Machine feed value" is set in "[Pr.14] Software stroke limit
selection".

value".
