Model FX2N-10PG Pulse Output Block
• Detection timing
Level detection : Effective while each bit is ON or OFF.
Edge detection : The change of OFF or ON is detected to start the operation.
• Priority sequence of start flag and stop flag
In each operation mode, the STOP command during operation is always valid, and is prior
to forward jog, reverse jog and start.
When the STOP command is ON, FX
command is turned ON, the remaining-distance operation or next positioning operation is
started. (Selection with BFM36 b15)
However, If forward jog (BFM#26 b4)/reverse jog (BFM#26 b5) is ON during jog operation,
the jog operation will be restarted when the STOP command is turned OFF.
• ON/OFF process of each flag
If ON or OFF is written into each flag, the state will be held until the power supply of FX
10PG is turned off.
Level detection is executed/stopped by writing ON/OFF.
Moreover, for edge detection, be sure to produce such a sequence program as each bit is
turned OFF after the assigned operation is executed by turning ON each bit.
(Unless each bit is turned OFF, the operation of 2nd time or following will be impossible.)
• Forward limit (b2) and reverse limit (b3)
When the forward/reverse limit (BFM#26 b2, b3) is turned ON, deceleration and stop will be
applied, and it will not be possible to travel in the direction of the limit switch which is turned
ON.
To drive away from the limit switch, use jog commands or a manual pulse generator in the
required direction.
