request flag ([Md.31] Status: b3) must be turned OFF).

return and an error will occur by a cleared amount.
• When unlimited length feed is executed by speed control and the machine feed value overflows or underflows once, the
fast home position return cannot be executed normally.
• The home position return complete flag ([Md.31] Status: b4) is not turned ON.
