Description
4 Encoder Pulse
Inputs the resolution of encoder provided in the line.
Setting Range
Calculation of encoder pulse number (5.00 to 600.00 P/mm)
Encoder Pulse
* 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 25.00 P/mm or more.)
5 Fly. Obj. Wait (Flying Object Wait)
Waiting period for marking corresponding to the line speed for flying object marking.
Setting Range
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
If the error occurs during the marking to flying object, adjust the following settings.
ERROR
CODE
The marking is performed after the work is
E620
moved to outside of marking field.
The marking is performed before the work is
E621
entered into the marking field.
The marking is not finished until the work is
E622
passed through the marking field.
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.
