4) ‘PT ACK’and ‘PT End’Output
‘PT ACK’ and ‘PT End’ signals are available only when the motion is executed by
position table. When PT ACK signal is set to ON and PT End signal is set to OFF, all
motion loops are finished. Then PT ACK signal becomes OFF and PT End signal becomes ON.
If the ‘Wait time’ value in PT item is not 0, the defined time is needed to PT End
signal becomes ON.
