Description
4 Encoder Signal
Enable this function when using the encoder. The setting parameter for the line speed is disappeared from the
screen and the parameter for encoder pulse number appears instead when pressing the box.
When the encoder
is not used : Performs marking to flying object by applying the calculated line speed already input.
When the encoder
is used : Performs marking to flying object by applying the calculated line speed which is derived
from the pulse sent from the encoder input to the input terminal.
5 Encoder Pulse
Inputs the resolution of encoder provided in the line.
Setting Range 5.00 to 600.00P/mm
Calculation of encoder pulse number (5.00 to 600.00P/mm)
Encoder Pulse =
Pulse number of one
rotation of encoder
÷
Line distance advanced during
one rotation of encoder
× 4 or 2 *
* When using A and B phase: 4
When using either A or B phase: 2
Reference
• Up to 100kHz per one phase is possible to be input to the encoder input on the input terminal block.
• Use only “A” phase (ENC(A)) of the input terminal block input and connect “B” phase (ENC(B)) to input common if
either of these encoders is used.
• If the setting value for the encoder pulse is too small, the marking quality might be deteriorate. (Depending on the
marking condition, the recommendation setting value for the encoder pulse is 25.00P/mm or more.)
6 Fly. Obj. Wait (Flying Object Wait)
Waiting period for marking corresponding to the line speed for flying object marking.
Setting Range 0.00 to 500.00ms
Adjust the waiting time of the marking for flying object so that the width of the character string is as shorten as
possible shown below when performing the test marking remaining the setting of the marking for flying object.
Too Narrow Proper Too Wide
If the error occurs during the marking to flying object, adjust the following settings.

Reference
• There might be the case that the marking is impossible even though adjusting the waiting time of the marking of the
flying object if there are a lot of marking data.
• When the pulse output from the encoder and actual motion of the line is not matched, the marking may not performed
properly.
