5 OPERATION CONTROL PROGRAMS
(10) When the target position change of address method to the axis of control unit
[degree] is executed, operation is as follows.
• The positioning to new address is executed in the current direction.
• Set "0 to 35999999 10
the outside of range is set, a minor error (error code: 260) will occur and
deceleration stop is executed.
(11) Operation for the movement amount to new target position is less than
deceleration distance required to deceleration stop from speed during control by
execution of CHGP instruction is as follows.
• A minor error (error code: 261) will occur and deceleration stop is executed at
execution of CHGP instruction.
• The difference between movement amount to the deceleration stop and
movement amount to new target position is overrun.
• The positioning complete signal (M2401+20n) does not turn ON.

(12) When the negative speed change is executed after execution of CHGP
instruction, a deceleration is executed to speed 0. Then, it returns to position at
target position change (CHGP instruction accept), and stops (waits) there.
