Setting details
Set the synchronous encoder
axis type to be used.
• Set the unit of the synchronous
encoder axis.
• Set the position unit within the
-9
range from 1 to 10 [control
unit].
• Set the speed unit within the
-9
range from 1 to 10 [control
unit/s or control unit/min].
Set the numerator to convert the
unit from the encoder pulse of the
synchronous encoder axis into
the synchronous encoder axis
unit.
Set the denominator to convert
the unit from the encoder pulse of
the synchronous encoder axis
into the synchronous encoder
axis unit.
Set the length per cycle of the
synchronous encoder axis.
Set the time to smooth for the
input value.
Set the time to advance or delay
the phase.
Set the time constant to affect the
phase compensation.
Set this parameter to restrict the
input travel value to one direction.
