Resolution of
synchronous encoder
via device
• Set the resolution of the
synchronous encoder when the
synchronous encoder axis type
is set to synchronous encoder
via device.
• If 0 is set, the input value of
synchronous encoder via device
is processed as 32-bit counter.

(1) [Pr.320] Synchronous encoder axis type
Set the synchronous encoder type to be generated of the input value for the
synchronous encoder axis.
• 0: Invalid ..............................................Synchronous encoder axis is invalid.
• 1 to 12: Synchronous encoder Pn ......Generate the input value based on the
synchronous encoder input of P1 to P12
assigned with the system setting.
• 201: Via device....................................Generate the input value with the value
set in the [Cd.325] Input value for
synchronous encoder via device
(10n, 10n) as the
encoder value.
(2) [Pr.321] Synchronous encoder axis unit setting
Set the position and speed unit of the synchronous encoder axis. Refer to
Section 5.3.1 for details.
(3) [Pr.322] Synchronous encoder axis unit conversion: Numerator,
[Pr.323] Synchronous encoder axis unit conversion: Denominator
The input travel value of synchronous encoder is configured in encoder pulse
units. The units can be arbitrarily converted through unit conversation with setting
[Pr.322] Synchronous encoder axis unit conversion: Numerator and [Pr.323]
Synchronous encoder axis unit conversion: Denominator.
Set [Pr.322] Synchronous encoder axis unit conversion: Numerator and [Pr.323]
Synchronous encoder axis unit conversion: Denominator according to the
controlled machine.

The travel value in pulses set in [Pr.323] Synchronous encoder axis unit
conversion: Denominator is set in [Pr.322] Synchronous encoder axis unit
conversion: Numerator in synchronous encoder axis position units (Refer to
Section 5.3.1).
The input travel value can be reversed by the setting negative values.
Set [Pr.323] Synchronous encoder axis unit conversion: Denominator" based on
encoder pulse units from the synchronous encoder.
Set a value within the range from 1 to 2147483647.
