■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 home position. When "current feed value" is set, the moveable range is the
relative range from the "current feed value".
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".
*2 Moveable range from the "[Pr.12] Software stroke limit upper limit value" to the "[Pr.13] Software stroke limit lower limit value".
Check details Processing when an
error occurs
1) An error shall occur 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".)
An "axis error" will occur
(error code: 1993H,
1995H, 1A18H, 1A1AH)
2) An error shall occur if the command address is outside the software stroke limit range. (Check "[Da.6] Positioning address/
movement amount".)
