2.2.3 Caution
• Change the setting of A510 after turning OFF the positioning preparation signal (input terminal function 178/179)
and run signal (input terminal functions 2/3, 4/5).
• Positioning control and the PID function cannot be used at the same time.
When A510=1, the normal PID function is disabled.
• When the run signal is turned OFF during positioning control, positioning control is stopped, and the motor is
decelerated and stopped in the deceleration time set in A511.
• When the positioning preparation signal is turned OFF during positioning control, E-46 trip occurs.
• To switch from positioning control to speed control, turn OFF the run signal during positioning control and turn
OFF the positioning preparation signal after the inverter stops.
• When all the multi-step point signals (input terminal functions 10/11, 12/13, 14/15)are turned OFF during
positioning control, rewrite the target position to the detection position at that time. Do not turn OFF all the multi-
step point signals when positioning is not completed. When it is completed, servo lock is continued in the current
position.
• If the current position becomes out of the range of - (A520, A521) to (A518, A519) during positioning control, the
position limit excess signal (output terminal function 214/215) is turned ON.
When A522=0, positioning control can be continued as it is, however, E-47 trip occurs when A522=1. Use this
function to prevent the machine from exceeding the range of movement.
• When movement in the same direction is repeated with the relative position command, clear the current position
as necessary so that the current position should not be out of the range of -(A520, A521) to (A518, A519).
For how to clear the current position, refer to 2.4.
• This function is available with the following speed feedback detection.
- PG feedback option (VEC008Z)
- resolver option (VEC010Z)
- S4, and S5 terminal (V114 or later)*
* Stop position control shortly after positioning is completed.
Do not use servo lock operation (continue to run at 0Hz).
