Model FX2N-10PG Pulse Output Block
3) When inch is used for setting
The following pulses are output for the positioning operation of travel 100 [ × 10
operation speed of 6 [inch/min].
Pulses generated = Travel stroke
Pulse frequency = Operation speed
*3 Units are matched for each calculation. 1inch = 10
• b5, b4 Magnification of position data
The position data which will be written into the zero point address (BFM#10, #9), target
address Ι (BFM#14, #13), target address ΙΙ (BFM#18, #17) and current address (BFM#25,
#24) can be magnified.
Setting of BFM#36 b5, b4
b5,b4 = 0, 0
b5,b4 = 0, 1
b5,b4 = 1, 0
b5,b4 = 1, 1
Example
When the content of the target address Ι (BFM#14, #13) is 123 and BFM#36 b5, b4 is set at
1, 1, the practical address (or travel stroke) becomes as follows.
