16. INDEXER POSITIONING OPERATION
Note 1. Configure a sequence that changes the next station selection (RYnA to RYnE and RY(n 2)3 to RY(n 2)5) and speed
selection (RY(n 2)C to RY(n 2)E) earlier, considering the delay time of CC-Link communication.
2. When the selected station number exceeds the value that is dividing number set in the parameter No.PC46 minus one, the next
station warning (A97) occurs.
3. The start (RYn1) is invalid even if it is turned on during operation. When executing another operation, turn on RYn1 after the
movement completion (RXnC) turns on.
4. Change of the servo motor speed and acceleration/deceleration time constant by the speed selection 1 (RY(n 2)C) to speed
selection 3 (RY(n 2)E) becomes effective when the start (RYn1) turns on. Even if the speed selection 1 (RY(n 2)C) to speed
selection 3 (RY(n 2)E) are changed during servo motor rotation, they do not become effective.
5. The following shows the operation to be executed.
6. Delay time from when RXn1 turns on until the torque limit value changes to the parameter No.PC35 value can be set in the
parameter No.PD26.
7. After power-on, if the current position is with the in-position range of each station, the in position (RXn1) turns on.
(2) When using the remote register
Select the station number using the next station (RWwn 4) remote register and execute positioning. For
the speed data during operation, select the point table number using the point table No./Speed command
data (RWwn 6) remote register, or directly set the servo motor speed.
