7.3 Operation of the Input and Output Flag Before and
After P Point Control

P point control start flag (

Ｙ

_1)

1. P point control is initiated based on the parameters written to the positioning unit.
2. Control is not initiated during the time that the pulse output busy flag (X_0) is ON. (it has already been
initiated).
3. Control is reset when the power supply is turned OFF.

Set value change confirmation flag

（

X_A

）

1. This goes ON with the next scan after P point control has been initiated.
2. It remains ON until the next F151shared memory write instruction is executed, and the new parameter
  is written to the shared memory, and then goes OFF after the parameters have been written to the
unit.
3. This is reset when the power supply is turned OFF.
-This is used for P point control, and the user must be careful that it does not overlap other control
  programs. (Refer to *section 7.4.)

Pulse output busy flag

（

X_O

）

1. This goes ON with the next scan after P point control has been initiated, and goes OFF when the
    pulse output is completed.
2. Operation cannot be shifted to any other operation while this signal is ON. (except for a forced stop
    and a deceleration and stop)
3. This is reset when the power supply is turned OFF.
-This flag is shared among E point control, P point control, JOG operation, JOG positioning operation
  and home return. (except a pulser input enabled operation)

Pulse output done flag

（

X_1

）

1. This goes ON when the pulse output is completed, and is maintained until the next E point control, P

point control, JOG operation, JOG positioning operation, home return, or pulser input enabled status
is initiated.

2. This is reset when the power supply is turned OFF.
-This flag is shared among E point control, P point control, JOG operation, JOG positioning operation
and pulser input enabled operation.
