<Target position change request flag>
1: Target position change request
• Do not turn ON the target position change request in
the following cases.
1) An operating pattern "continuous path control" is
used.
2) A control system other than ABS1, and INC1 is
used.
3) During deceleration stop.
4) When speed change 0 flag (
Md.31 Status: b10) is
ON.
5) During speed control mode
6) During torque control mode
7) During continuous operation to torque control
mode
• When the target position change address is outside
the software stroke limit range, correct the target
position change address. (Refer to Section 13.5.5)

• Set the torque initial value selection invalid to
command torque.
