Jogging/teaching timing
T1: 40 msec or more; time after the current-position write input is turned ON until writing of the current position
is completed. If an alarm generate, the writing time may become longer due to alarm registration.
 When the operation mode (MODE) input is turned ON, the mode status (MODES) output will turn ON and the
teaching mode permitting PIO teaching will become effective.
Once the controller switches to the teaching mode, the start (CSRT) signal will change to the current-position
write (PWRT) signal, while the position complete (PEND) signal will change to the write complete (WEND)
signal.
The teaching mode will not become effective unless the operation mode (MODE) input is turned ON while the
actuator is stopped.
 To confirm that the teaching mode is effective, check if the current operation mode (MODES) output is ON.
 If the Jog+ input or Jog- input turns ON, the actuator will turn ON. Turning both inputs OFF will stop the
actuator.
While the actuator is moving, the moving (MOVE) signal turns ON.
If both the JOG+ move input and JOG- move input turn ON simultaneously, however, the actuator will stop.
In this case, turn OFF both signals and then resume the jogging operation.
 The manual operation switching (JISL) input is ON during inching and OFF during jogging.
The inching distance is set by parameter No. 48, while the jog speed is set by parameter No. 26.
 If the current-position write (PWRT) input has remained ON for 20 msec or longer, the current actuator
position will be written to the selected command position number.
When writing is completed, the write complete (WEND) output will turn ON.
When the current-position write (PWRT) input is subsequently turned OFF, the write complete (WEND)
output will turn OFF.
(Note) If the current-position write (PWRT) signal turns OFF before the write complete (WEND) signal turns ON,
the write complete (WEND) signal will not turn ON. Always turn the current-position write (PWRT) signal
OFF after confirming that the write complete (WEND) signal has turned ON.
If a signal to be written is input from the PLC while the position table screen is open on the PC or teaching
pendant, the position data display will not be refreshed. Perform one of the following operations to check the
retrieved position data:
PC ----------------------- Click the
button.
Teaching pendant --- Open the user adjustment screen and enter “4” as the adjustment number to reset the
software.
