2.2 Synchronous Encoder Axis
Setting details
• Set the synchronous encoder axis
type to be used.
Fetch cycle: At power supply ON
• Set the unit of the synchronous
encoder axis.
• Set the position unit within the range
from  1 to 10 -9
[control unit].
• Set the speed unit within the range
from  1 to 10 -9
[control unit/s or
control unit/min].
Fetch cycle: At power supply ON
• Set the numerator to convert the unit
from the encoder pulse of the
synchronous encoder axis into the
synchronous encoder axis unit.
Fetch cycle: At power supply ON
• Set the denominator to convert the
unit from the encoder pulse of the
synchronous encoder axis into the
synchronous encoder axis unit.
Fetch cycle: At power supply ON
• Set the length per cycle of the
synchronous encoder axis.
Fetch cycle: At power supply ON
• Set the time to smooth for the input
value.
Fetch cycle: At power supply ON
• Set the time to advance or delay the
phase.
Fetch cycle: Operation cycle
• Set the time constant to affect the
phase compensation.
Fetch cycle: At power supply ON
• Set this parameter to restrict the input
movement amount to one direction.
Fetch cycle: At power supply ON
• Set the resolution of the synchronous
encoder when the synchronous
encoder axis type is set to
synchronous encoder via CPU.
• If 0 or less is set, the input value of
synchronous encoder via CPU is
processed as 32-bit counter.
Fetch cycle: At power supply ON
