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
-9
1 to 10
[control unit].
• Set the speed unit within the range from 1
-9
to 10
[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
